Technical Information
HIGH-ABUSE WIRING DEVICES — UL LISTED HOSPITAL GRADE
Why was it developed?
Hospital Grade Listed devices were developed to provide maximum safety in high-abuse applications where constant strenuous use of the device is common. These highest reliability devices are built to protect against possible human negligence and keep the devices safe and functional.
What are the applications for Hospital Grade, High Abuse Devices?
3PVHIVTFPDDVSTOPUKVTUJOIPTQJUBMTCVUFWFSZQMBDFXIFSFQFPQMFDBOUPSXPOUCFDBVUJPVTXJUIEFWJDFTyUIFDMFBOJOHQFSTPOXIPZBOLTUIFnPPSXBYFSQMVHEPXOUIFIBMM
the mechanic who pulls the drill plug from the wall, or the child who removes the electric lawnmower plug from 40 feet away! In addition, Leviton realized that devices in rough
use situations are often exposed to many corrosive liquids, such as cleaning fluids, rug shampoos, chlorinated water, sprays, salt air and chemical fumes. Our corrosion resistant
devices permit use in environments where these conditions are common.
Demanding Tests for UL Hospital Grade Listing
Leviton has designed a line of wiring devices that withstand impact, wear, crushing, and corrosive environments that would destroy ordinary heavy-duty devices. Leviton’s
comprehensive line of Hospital Grade and Industrial Grade plugs, connectors and receptacles include devices that have passed a series of demanding UL Hospital Grade tests.
This assures the end-user of top performance in the harshest industrial environments. Here are examples of how Leviton devices meet or exceed the requirements of the most
rigorous testing!
Receptacles
Abrupt Removal of Plug Test
Plugs and Connectors
500 lb. Crush Test
A steel-bodied test plug with brass blades
is inserted into the receptacle. A 10-pound
weight dropped from at least 24 inches
yanks the plug out of the receptacle. This
test is done eight times with the receptacle
rotated into different positions to create the
greatest stress on its face and contact. After
this, the grounding contact must retain a
four ounce, 0.184” diameter grounding pin,
with the receptacle face down, for one minute.
“There shall be no breakage of the receptacle
that interferes with the receptacle function or
the integrity of the enclosure. The receptacle
shall maintain the grounding path integrity
through the receptacle.”
A wired plug or connector is placed between
two steel plates and subjected to a force
which is steadily increased to 500 pounds.
“There shall be no breakage, deformation
or other effect that may interfere with the
function of the device.” Leviton knows that
in real industrial environments, plugs and
connectors are crushed by forces exceeding
500 lbs. Leviton performs the crush test with
force of 2500 lbs. to ensure that our devices
withstand the really heavy hits on the job.
Ground Pin Test
The grounding contact of the receptacle is
conditioned by 20 insertions with a 0.204”
diameter oversized pin. “After conditioning,
a 0.184” diameter pin shall be inserted in
the grounding contact and shall be capable
of supporting at least four ounces for
one minute.”
Impact Test
A wired plug or connector is subjected to
impact from a 10 lb. weight dropped from
a height of 18 inches. “There shall be no
breakage, deformation or other effect
that may interfere with the function of the
device.” Plugs and connectors are subjected
to severe impacts in industrial settings.
Therefore, Leviton exceeds the UL requirement by dropping the weight from a height
of 36 inches.
Cord Pull Test
Power Blade Retention Test
A test plug with oversized blades of .075” is
inserted into the current-carrying opening of
the connector for 20 conditioning cycles.
After the conditioning cycles, “the contact
shall be capable of supporting for one minute
11⁄2 lbs., secured to a single .055” thick solid
steel blade without holes.”
The cord must remain securely fastened after
straight pulls of 30 pounds, and rotating pulls
(in a 3-inch circle) of 10 pounds for two hours.
“Displacement of conductors, insulation, and
outer jacket of the flexible cord AWG 18 SVT
shall not exceed 1/32 inch. There shall be no
cuts, rips, or tears in cord insulation.” Heavyduty cord stress is typical abuse for industrial
plugs and connectors. Leviton increases the
weight in the straight cord pull test to 175 lbs.
with AWG 14 ST and in the rotating pull test to
20 lbs., ensuring positive strain relief under
industrial conditions.
Mechanical Drop Test
A sample wired plug or connector is
suspended horizontally by its attached cord
and released so that it impacts a hard wood
surface 45 inches below the point of
suspension — repeated for 1300 cycles.
“There shall be no breakage, deformation or
other damage which would interfere with the
functioning of the device.”

SWITCHES
DIMMERS
Types of Switches
A common misconception about box-mounted dimmers is that they are simply
variable resistors (rheostats) that absorb power to dim the lights. In fact, a rheostat would be too bulky, inefficient and heat producing to ever be practical as a
wall-mounted dimmer. In the 1950’s, the advent of solid state technology and a
type of semi-conductor called the TRIAC fostered the development of full-range
dimmers and fan speed controls that were versatile, efficient and compact enough
to fit in a standard wallbox.
Leviton has always taken an active role in the development of lighting control
technologies. Leviton introduced the Trimatron™ Rotary Dimmer that was only
half as deep as conventional dimmers, allowing easier installation and wiring in a
crowded wallbox. Today, Leviton offers innovative all-digital lighting controls that
feature scene lighting and multi-location control capabilities for sophisticated
residential and commercial installations. Leviton’s complete line of controls for
incandescent, low-voltage and fluorescent lighting includes Decora® and architectural specification grade devices, as well as traditional rotary devices. There is also
a wide selection of Fan Speed Controls
Switches used in branch circuit wiring are rated in two general categories: AC ONLY
and AC/DC. Originally, the electrical power furnished to residences and businesses
by utility companies was Direct Current or DC. Because DC current was always
flowing at full value, the making or breaking of a circuit created a rather strong
arc during switch operation. For this reason, the contacts had to be widely gapped
and the operation had to be “quick make, quick break” to avoid excessive pitting
or welding of the contact points. Alternating current operates between zero and
full power 120 times per second. Because of the oscillating characteristic of AC
power, the arc from an AC circuit is self-extinguishing on the “break” of the current.
This means a slower breaking action is possible on an AC switch, as opposed to
the breaking action required of a switch made for use with continuous full-power
DC. The pulsating nature of AC can, however, cause a “chattering” or very fast
series of “makes” and “breaks” if the circuit is closed too quickly. For this reason an
AC ONLY switch works with a somewhat slower “fast make” and “break” than an
AC/DC switch. Because the make and break actions of an AC/DC switch must be
fast, it can be rather noisy, and must use contact metals capable of enduring such
comparatively violent action while still offering acceptable electrical conductivity.
An alloy of copper is most often used. Silver and its oxides are better conductors
than copper and its oxides. Silver is much softer than copper and therefore cannot
be used in the AC/DC switch. However, silver can be used in the AC ONLY switch
because of its gentler “fast make” characteristic, especially when silver is alloyed
with cadmium oxide, a good conductor that’s quite hard.
Switch Ratings
AC ONLY switches are often called AC Quiet switches because they can be made
to operate very quietly, unlike AC/DC switches. AC ONLY switches are rated at
their full current value for lighting, including tungsten filament, quartz metalhalide, and fluorescent; and 80% current value or full horsepower rating value for
motor (inductive) loads. AC/DC switches used for incandescent lighting should
have a “T” rating (tungsten-filament rating). The “T” rating assures end-users of
the longevity of the switch through the surge currents of a “make” action across
a tungsten filament. Such capacity is already inherent in the design of AC Quiet
switches. AC/DC switches are rated at only 50% of their current capacity for motor loads. A 20 amp AC/DC switch could be used to control a 10 amp motor load,
while a 20 amp AC Quiet switch can operate a 16 amp motor load.
In the past, MERCURY switches were available that operated by making and breaking contact within a hermetically sealed capsule containing a pool of mercury.
MERCURY switches were actually silent in operation. However, due to health
concerns about mercury, these switches are no longer manufactured and sold.
MERCURY switches may still be in service in some installations.
Horsepower Ratings
Switches marked with Horsepower (HP) Ratings are suitable for controlling the
motor loads of the HP ratings shown on the switch, as well as loads with a lower
HP rating. To qualify for an HP rating, a switch is tested at six times the full motor
load current corresponding the HP rating marked on the switch. For DC motor load
controllers, the test is made at 10 times the full motor load current corresponding
to the DC HP rating marked on the switch. The test is conducted on six samples
and consists of 50 On-Off operations at the load. For a 3/4 HP rating at 120/240
VAC, two sets of six samples each are tested in addition to the regular overload
endurance, heating and insulation tests. The test circuit characteristics are:
Closed Circuit Volts

Note: The current at 240 VAC is 1/2 that at 120 VAC.
All switches must be in good operating condition after the tests have been completed. There must be no
excessive arcing, welding or burning of the contacts nor arc-over to ground (the switch frames are grounded
during the Stalled Rotor Test).

RECEPTACLES
Types of Receptacles
Receptacles generally are made to accommodate either of two types of plugs.
Straight-Blade plugs are pushed in and pulled straight out. Locking plugs are
pushed in and rotated slightly in a clockwise direction to a position were they
cannot be pulled straight out. They must be rotated counterclockwise back to
the insertion position in order to be withdrawn. This locking action is intended to
prevent accidental disconnection of the circuit by pulling the plug straight out
unintentionally.
Grounding
Originally, residential electrical circuitry was “2-pole, 2-wire” and did not have an
equipment grounding means at the receptacle. The only grounding point was at the
service entrance, where the neutral (white) conductor was grounded. The receptacle slot for the neutral wire, according to NEMA configuration 1-15R, must be longer
than the slot for the phase or hot wire (typically black or red). This enables certain
items of equipment, like TV sets and home appliances, to have their external metal
parts or casing grounded through the white neutral connection. Such equipment
uses a polarized plug where the neutral plug blade is wider than the hot plug blade,
ensuring that it mates properly with the NEMA 1-15R configuration receptacle.
Receptacles designed for 2-pole, 2-wire circuits do not have mounting straps that
are connected to a grounding terminal. Leviton still offers 2-pole, 2-wire receptacles
for replacement use only in existing non-grounding systems.
Experience proved that a single grounding point through the neutral conductor was
not sufficiently safe. Conditions could occur where fault currents and differences
in potential lead to shocks, overheating, equipment burnout and fire. Therefore,
the 2-pole, 3-wire circuit was developed. A third conductor, called the grounding
conductor, does not carry current during normal circuit operation. It is connected to
the neutral bus bar at the service entrance and runs along with the current-carrying
neutral and hot conductors. The grounding conductor is connected only to outlet
boxes, chassis and other non-current carrying components that may carry current
in case of damage or defects in the wiring system. It is sometimes referred to as the
“equipment grounding conductor.”
The grounding contacts on the 2-pole, 3-wire receptacles are most commonly
shaped like a “U”, which is how the term “U-ground” evolved. The grounding contacts on these receptacles are securely fastened to the mounting strap. In Leviton
receptacles, the grounding contacts are permanently riveted to the mounting strap,
and in most Leviton Hospital Grade and Industrial Grade receptacles they are an
integral part of the strap. Many Leviton receptacles offer dual ground connection
options to help ensure that the receptacle is properly connected to the grounding
system: An integral green grounding screw for direct connection to the green or
bare grounding wire, and a patented Groundamatic® self-grounding clip riveted to
the strap to provide automatic ground connection when the receptacle is mounted
in a properly grounded metal wallbox.

Technical Information
Isolated-Ground Receptacles
Although the conventional grounding system provides safety for personnel and equipment, it may be a source of electrical
interference that can cause problems in modern electronic equipment. Because the conventional grounding network runs
through an entire facility, it can unintentionally function as a pick-up of transient electrical signals or “noise.” These transient
signals will then be introduced to equipment through the ground connection. Microprocessor-based equipment, including
computers, cash registers, medical equipment and audio/video equipment, may malfunction as a result of this noise. IsolatedGrounding Receptacles can help eliminate problems caused by electrical interference in a conventional ground system. The
ground contacts on Isolated-Ground Receptacles are electrically isolated from the mounting strap and therefore they are
isolated from the conventional ground system. The green ground screw is connected to a pure ground path that is separate
from a facility’s grounding network. The isolated ground network is relatively free of electrical noise because it is not a
facility-wide grounding path and it’s connected to ground at a single point.
ISOLATED-GROUNDING
RECEPTACLES
Mounting Straps
There are basically two kinds of mounting straps for receptacles. The “through” type passes between the receptacle body and cover.
The “wrap-around” type acts as a cradle for the receptacle, surrounding its side, ends and bottom surfaces.
Power Contact Design
The “contact” does more than make contact with the plug blade — it must grip the plug blade for maximum electrical conductivity and mechanical strength. Leviton
receptacles feature double-wipe contacts that grip both sides of each blade, including the U-ground contacts that are often single-wipe in receptacles made by other
manufacturers. Leviton Hospital Grade and Industrial Grade receptacles feature triple-wipe contacts for added strength and durability in high-abuse applications. Leviton
contacts are made of the copper alloys that offer maximum strength and electrical conductivity.

GROUND FAULT CIRCUIT INTERRUPTERS (GFCIs)
The Need for Ground Fault Protection
UL 2006 Code Requirements (Effective July 28, 2006)
Circuit breakers and fuses protect equipment and building structures from overheating and fire caused by short circuits and high-current overloads. However, the current level needed to trip a breaker is many times greater than the amount of current
needed to deliver a powerful, and possibly lethal electrical shock. For example, the
hot conductor in an electrical device can become exposed through a break in its
insulation, and it may end up touching the device’s metal enclosure. The leakage
current that now flows through the metal enclosure will be conducted to ground
through any available path — including the body of a human being that happens
to touch the faulty device. This condition is called a Ground Fault, and the current
flowing through the person to ground can be life threatening, though there is usually
nowhere near enough current to trip a circuit breaker.

protection based on a failure to pass their internal test
How a GFCI Works
Note that the National Electrical Code strongly recommends monthly testing of all GFCIs.
Leviton SmartlockPro® GFCI with Lockout Action
The TEST and RESET functions on Leviton’s SmartlockPro® GFCI work together so
that a tripped GFCI cannot be reset if the GFCI circuit is no longer providing ground
fault protection. The RESET button is blocked if GFCI protection has been compromised, eliminating the possibility of end-users incorrectly assuming that a reset GFCI
is providing ground fault protection when it actually is not.
When there is a ground fault condition, all of the current flowing through the “hot”
conductor is not returning through the neutral conductor. A Ground Fault Circuit
Interrupter (GFCI) monitors the difference in current flow between hot and neutral
conductors. If the GFCI senses even a very tiny difference in current flow between
the conductors (a ground fault), it interrupts the flow of electrical current through
the device by opening its internal double-pole contacts. According to UL Standard
943 Class A, the GFCI must trip when there is a ground fault of 5 milliamps (±1mA).
The GFCI must also trip within approximately 25 milliseconds. GFCI receptacles are
rated for 15 or 20 amp circuits. They are used in place of standard box-mounted duplex receptacles. GFCI receptacles can also be feed-through wired to provide ground
fault protection to feed-through wired receptacles downstream.

ENCLOSURE TYPE DESIGNATIONS
Enclosures serve the dual purpose of protecting personnel from incidental contact with the enclosed electrical equipment and protecting the enclosed equipment against
specified environmental conditions. Enclosures are rated for use in specific environmental conditions by NEMA, UL, CSA and the IEC. The major rating systems used are the
NEMA Type Numbers and the IEC Enclosure Classification Designation.
The IEC Enclosure Classification Designation — IP Suitability Ratings
The IP Suitability Ratings are a system for classifying the degree of protection provided by enclosures of electrical equipment. The higher the number in the rating, the
greater the degree of protection provided by the enclosure. Note that the rating will ONLY apply to properly installed equipment. The chart below defines the numerals in
the IP Code.
1. The First Numeral indicates the degree of protection for persons against access to hazardous parts inside the enclosure and/or against the ingress of solid foreign objects.
2. The Second Numeral indicates the degree of protection of equipment inside enclosures against damage from the ingress of water.

TESTING STANDARDS
About PSI Ratings
PSI is an abbreviation for pounds per square inch. With respect to water
washdowns in processing plants and industrial marinas, a PSI value should
specify the distance from the nozzle at which the value was taken. Consider
the following situation: 1,000 PSI measured 2 inches from the plug/connector
or 2 ft. from the plug/connector will deliver dramatically different forces.
Leviton Wetguard devices are tested and exceed IEC and UL watertight standards.
These independent tests have defined parameters as noted below:
IEC IP Water Penetration Test:
Water is sprayed from a distance of 3 meters and at a rate of 100 liter/minute
on a joined plug and connector using a 12.5mm diameter nozzle. The water
spray is directed at the connector/plug joint and cable entries.
Result: Wetguard Plugs and Connectors are rated to IP67 when connected.
UL NEMA Water Penetration Test:
Water is sprayed from a distance of 12 ft. and at a rate of 65 gallons/minute on a joined plug and connector using a 1 inch diameter
nozzle. The water spray is directed at the connector/plug joint and cable entries.
Result: Wetguard Plugs and Connectors are rated to NEMA 4X, 6, and 6P when connected.

NEMA AND IEC ENCLOSURE CLASSIFICATIONS
Comparing NEMA Enclosure Type Numbers and IEC Enclosure
Classification Designations (IP Suitability Rating)
IEC
IEC Publication 529, “Classification of Degrees of Protection Provided by Enclosures,”
defines the IP (Ingress Protection) Suitability Rating. The IP Suitability Rating is a
system for classifying the degree of protection provided by enclosures of electrical
equipment. The higher the number in the rating, the greater the degree of protection
provided by the enclosure. The first numeral of the code indicates the degree of protection for persons against access to hazardous parts inside the enclosure and/or
against the ingress of solid foreign objects. The second numeral indicates the degree
of protection of equipment inside enclosures against damage from the ingress of
water. The IP Suitability Rating defined by IEC 529 does not specify any degree of
protection against mechanical damage of equipment, risk of explosions, or conditions such as moisture (i.e. condensation), corrosive vapors, fungus, or vermin.
Phosphor Bronze
Phosphor Bronze, an alloy of copper and tin, is superior in strength to 70/30 brass.
The advantage of using phosphor bronze parts is that they can be thinner than
comparable parts made of standard brass without any loss in strength. For example,
Leviton uses a phosphor bronze alloy of 95% copper and 5% tin to form power contacts in some Industrial Grade receptacles. Phosphor bronze power contacts at .031”
outperform brass power contacts of a thicker gauge.
Beryllium Copper
An alloy of copper and .5% beryllium is used to form some of the components in
Leviton Industrial Grade devices. Beryllium Copper provides excellent strength, durability, electrical conductivity. It also retains its resiliency at elevated temperatures.
These properties make Beryllium Copper ideal for the contact arm in heavy-duty
switches.
Silver-Cadmium Oxide
NEMA
NEMA Standards Publication 250 defines the NEMA Enclosure Type Numbers. Unlike
the IEC Enclosure Classification Designations, NEMA Standards Publication 250 does
tests for environmental conditions such as corrosion, rust, icing, oil and coolants.
For this reason and because the tests and evaluations for other characteristics
are not identical, the IEC Enclosure Classification Designations cannot be exactly
equated with NEMA Enclosure Type Numbers. The table below provides an equivalent conversion from NEMA Enclosure Type Numbers to IEC Enclosure Classification
Designations. Note that the NEMA Types meet or exceed the test requirements for
the associated IEC Classifications. Therefore, this table cannot be used to convert
from IEC Classifications to NEMA Types.

Although pure silver is an excellent conductor (superior to copper), it cannot be used
for switch contacts. Over time, arcing caused by actuation would weld the silver contacts together. Silver-cadmium oxide, an alloy of 90% silver and 10% cadmium oxide,
is widely used by Leviton to form switch contacts. Microscopic particles of cadmium
oxide in the silver will decompose due to the heat buildup, preventing the contacts
from welding together.
Zinc-Plated Steel
In additon to being strong and durable, zinc-plated steel provides a higher degree of
corrosion resistance than standard cold-rolled steel. Leviton uses zinc-plated steel
mounting straps in many of its devices. Leviton also offers zinc-plated steel
wallplates for power receptacles, available with either a brass or aluminum finish.
Nickel-Plated Metals
Nickel-plating adds a high degree of corrosion resistance to either brass or steel. All
the metal parts in Leviton Corrosion Resistant devices (blades, contacts, terminals,
mounting straps and screws) are nickel-plated for maximum corrosion resistance. In
some cases, cupronickel screws are used, which provide a high degree of corrosion
resistance.
Leviton uses an electroless nickel-plating process. The standard plating process uses
an electrical charge to coat the metal with nickel. This can produce uneven results,
leaving some areas of the metal more coated than others. The more effective
electroless process involves submerging the metal in a chemical bath where salts
decompose and deposit nickel on the metal substrate. Every surface of the metal
is evenly coated. Leviton uses this electroless process to ensure that its Corrosion
Resistant wiring devices provide maximum performance in extremely damp and corrosive environments.
Stainless Steel
Type 430 Standard Stainless Steel
Materials Used in Wiring Devices
The following is an overview of the materials commonly used in wiring devices.
Note that specific brand names of materials used in Leviton devices are subject
to change due to a variety of factors. These changes will never compromise the
quality, performance and durability features of our wiring devices. Leviton is
committed to maintaining the positive qualities of the materials being replaced
and choosing new materials with superior qualities as they become available.
Brass
The type of brass commonly used in wiring devices is referred to as standard or
“70/30” brass. It is an alloy of 70% copper and 30% zinc that provides the strength
and conductivity needed for power and ground contacts, wiring terminals and terminal screws. It is also used for some mounting straps and wallplates.
The Olin Corporation offers a series of alloys sometimes referred to as High
Performance Brass or “Olin Brass.” Olin brass is a copper alloy consisting of more than
90% copper. It is more resilient than 70/30 brass and used by Leviton to form the
power contacts in some Industrial Grade and Hospital Grade devices.
For technical support call 800-824-3005
Type 430 stainless steel is resistant to the corrosive effects of moisture.
Leviton offers a wide selection of wallplates made from this material. Leviton’s
Raintight-While-In-Use Covers are supplied with stainless-steel mounting
screws to help ensure a long service life in wet applications. Note that Type 430
Stainless Steel does have magnetic properties that may interfere with magnetic-sensitive equipment.
Type 302/304 Non-Magnetic Stainless Steel
Type 302/304 Non-Magnetic Stainless Steel is suitable for applications where sensitive equipment may be affected by magnetic material. For example, navigational
equipment in marine applications and MRI equipment in health care environments
are susceptible to magnetic interference. In addition to being non-magnetic, Type
302/304 stainless Steel is more corrosion resistant than Type 430 stainless steel.
Types 302 and 304
differ in composition, but there is virtually no difference between them in terms of
non-magnetic and corrosion-resistant properties.

NEMA AND IEC ENCLOSURE CLASSIFICATIONS
Leviton offers a complete selection of wallplates made of Type 302/304 NonMagnetic Stainless Steel. These wallplates are ideal for any application where magnetic interference must be avoided. Leviton’s Corrosion Resistant wiring devices
feature non-magnetic stainless steel assembly screws to ensure their suitability in
marine applications. For health care applications where non-magnetic devices are
desired, Leviton’s Corrosion Resistant devices should also be used.
CO/ALR Devices
Aluminum is used for residential wiring in Europe because it is a good conductor and
considerably cheaper than copper. Houses with aluminum wiring were built in the
United States, but the practice stopped at least twenty years ago. It was
discovered that poor connections between aluminum wire and steel or brass
terminal screws led to serious fires. There are still homes with aluminum wiring, and
the National Electrical Code stipulates that only CO/ALR devices are to be used in
these applications.
Aluminum wire tends to oxidize over time, and the oxide layer does not conduct
electricity. This results in a poor connection with the wiring device terminal screws,
particularly if they are steel. The connections gradually heat up to the point where
fires are started inside the walls. For this reason, all standard wiring devices contain
the warning, “For use with copper or copper-clad wire ONLY. Do not use with aluminum wire.” The only exception to this are CO/ALR wiring devices.
Leviton offers a selection of CO/ALR devices for use with aluminum wire. In CO/
ALR devices, the terminal screws are plating with the element Indium. Indium is an
extremely soft metal that forms a gas-sealed connection with the aluminum wire,
eliminating problems caused by oxidation.
Thermosets
Thermoset components are manufactured by compression molding, where powdered material is molded by heat and pressure. Thermoset materials cannot be
remolded. The major types of thermoset materials are Phenolic, Urea and Melamine.
Phenolic is primarily used for dark colors, while Urea is used for lighter colors.
All thermoset materials provide dimensional stability when used in wiring devices.
Phenolic is also a flame-resistant material. Thermosets do not provide a high degree
of resistance to impacts, chemicals and solvents, and therefore they are not suitable for heavy-duty applications. Thermosets are not used in Leviton Industrial
Grade devices. Urea is still widely used to manufacture wallplates.
Thermoplastics
Thermoplastic components are manufactured by injection molding where pellets
of the material are heated to a liquid which can flow into a mold. Unlike thermosets, thermoplastics can be remolded. These materials are the preferred choice
for heavy-duty applications because they provide superior resistance to impacts,
chemicals
and solvents compared to thermosets. The following is a list of the major types of
thermoplastic materials, along with some well-known brand names.

*This chemical resistance code applies to general applications. Additonal testing is performed to determine resistivity to chemicals in specific environments.
Thermoplastic Enhancements
UV Stability
Glass-Reinforced Thermoplastics
Thermoplastics provide varying degrees of UV (Ultraviolet Light) stability. For example,
standard grade nylon will lose tensile strength and durability when exposed to sunlight
and weathering. Discoloring will also occur. There are additives that will increase the UV
stability of thermoplastics. UV Stabilized thermoplastics should be used when a device is
intended for extensive outdoor use. For example, Leviton uses UV- stabilized Lexan in its
Raintight-While-In-Use Cover, with excellent results.
Several types of thermoplastics are available in glass-reinforced versions,
including Rynite ®, Lexan ®, Valox ® and nylon. Glass reinforcement increases
the rigidity of the material and also raises the operating temperature.
For example, Leviton Momentary and Maintained Contact Switches feature
glass-reinforced thermoplastic construction, making these switches ideally suited
for rugged applications.

TELEPHONE WIRING DEVICES CODES AND STANDARDS
Industry Standards
At Leviton, our concern since deregulation has been the proliferation of poor quality
devices and equipment being attached to the network. These devices meet few
of the customary standards for mechanical integrity and combustibility and have
caused a number of problems for those who have installed them.
The responsibility for ensuring that no sub-standard devices are connected to the
network rests on everyone’s shoulders. In fact, the FCC recently issued a Public
Notice strongly reminding manufacturers, carriers and customers that the manufacture and installation of substandard devices and equipment will not be tolerated —
and that a substantial fine is the penalty for noncompliance. Recently, organizations
such as the Federal Communications Commission (FCC), Underwriters Laboratories
(UL), the Canadian Standards Association (CSA), and the Telecommunications
Industry Association (TIA) have been developing standards for premise wiring systems, Additionally, Article 800 of the National Electrical Code (NEC), published by
the National Fire Protection Association (NFPA), mandated “listing” of equipment
connected to telecommunications networks. Leviton has always played a role in the
standards-making process and will continue to do so. We wholeheartedly support
this new standards environment.
t5IFiFYUSBPSEJOBSZQSPDFEVSFTwBDDFQUBODFUFTUJOHBOEDBSSJFSOPUJmDBUJPOGPSXJSJOH
clause has been eliminated. The carrier is no longer required to take steps to protect
the network from harm when there is a violation of Part 68, a failure during testing
of newly installed wiring, or when harm has actually occurred. Once again, because
the carriers now have less access to the customer premise, they will also have less
responsibility in maintaining the network.
t$VTUPNFSQSPWJEFEBTXFMMBTDBSSJFSQSPWJEFEQMVHTBOEKBDLTNVTUNFFU4VCQBSU
F of part 68 when newly installed on ar after January 1, 1991. Prior to this ruling,
Part 68 could be interpreted to require that only the jack at the network interface
conform to Part 68.
Beware of the Number Game
FCC Part 68, Subpart F, specifies that contacts in the telephone jacks must have 50
micro-inches of gold over 100 micro-inches of nickel. Some manufacturers claim
.5 microns of gold plating on their jack contacts. At 39.37 micro-inches per micron,
that’s only 19.7 micro-inches — less than half of what is required to meet FCC Part 68
specifications. If jack contacts have not been plated with the right thickness or quality
of gold, corrosion at these critical points can cause signal degradation, equipment
failure, and even damage to the public telephone network. Data networks are more at
risk because even slight imperfections result in transmission error or data loss.
Reduce Risks — Specify Leviton
Industry Basics: Drawing the Line
The dividing line between public network and customer premises is called the
demarcation point. Equipment, including wiring, on the network side of the
demarcation point is the property and responsibility of the local telephone company
(telco). Equipment and wiring on the customer side is the responsibility of the
customer, who may procure equipment, materials, and service from the provider of
their choice. A subscriber network interface (SNI) often called a “demarcation jack”,
is recommended to be installed at the demarcation point. A standard registered jack
is often used at this point so that the network and the premise wiring system can
be quickly separated from each other. The location of the SNI depends on local rules
and on such factors as the number of units in the facility, access, and the type and
age of connecting hardware. The SNI may be inside the building or outside.
FCC Part 68 Requirements
The equipment standards outlined in FCC Part 68 were developed long before
divestiture to assure consumers, manufacturers and carriers that terminal
equipment and wiring could be connected without degrading the network. Part
68 describes minimum requirements for the mechanical or physical properties of
wiring devices such as the amount of gold on jack contacts, electrical performance,
dimensional integrity, material properties, and spring characteristics of contacts.
Only equipment meeting FCC Part 68 standards may be manufactured and
connected to the network. The vast changes that have occurred in the industry
because of evolving deregulation have made it necessary to modify Part 68. To
this end, FCC Wiring Docket 88-57 was issued in 1990. There have been numerous
attempts to change this docket; however, as of this writing, the following guidelines
are true:
t4JODF1BSUTQFDJmFEUIBUBMMDPOOFDUJPOTUPUIFOFUXPSLCFNBEFUISPVHI
the standard plugs and standard telephone company-provided jacks described
in Subpart F or Part 68. Now, Docket 88-57 permits customers to connect to the
carrier’s jack or wiring.
t5IFEFNBSDBUJPOQPJOUIBTCFFOSFEFmOFEUPCFOPUNPSFUIBOJODIFTGSPNUIF
protector, or when no protector is present, 12 inches from the point of entry to
the premises. In the past, the demarcation point could extend into the customer
premise hundreds of feet, if necessary, depending on the wiring application. The
new 12-inch ruling limits the carrier’s access to the customer premise.
tThe carriers are not responsible for customer wiring unless they have an agreement for
such responsibility. Because the customer can now install a jack at the network interface,
the customer is responsible for any wiring errors and malfunctions that occur.
814
There are no two ways about it. The risk to your operation and equipment is so great
that it only makes sense to insist on top-quality station products. When you specify
Leviton jacks, you’re assured maximum contact life with minimum resistance. We start
with durable phosphor-bronze contacts and plate them with a full 50 micro-inches
of lubricated hard gold over 100 micro-inches of nickel (or the electrical performance
equivalent as specified in FCC Part 68 requirements). Jack openings are built within
precise tolerances. High-quality thermoplastic rated UL 94V-0 resists distortion from
changes in temperature and humidity, physical stress, and aging. Spring contacts are
engineered to maintain positive contact pressure over the life of the device.
Telecommunications Industry Association Standards
If FCC regulations protect the telephone network from harm and UL requirements
protect the consumer from harm, who is responsible for providing performance
standards for the telecommunications industry? Recently, the FCC asked the
Telecommunications Industry Association (TIA), a sister organization of the Electronic
Industries Association (EIA), to take on this task, and they accepted the challenge. The
TIA was asked to define minimum standards for such things as how to wire a building,
what kind of wire to use, and so on. The following standards went into effect in 1991.
tPathway Standard (EIA/TIA 569-A): This standard for installing pipe and conduit
in commercial buildings is now available through TIA and the American National
Standards Institute (ANSI).
tResidential/Light Commercial Wiring (EIA/TIA 570): A draft of this standard,
which applies to premises with up to four telephone lines, has been reviewed by
ANSI and TIA committees and released.
tCommercial Wiring Standard (EIA/TIA 568-A): The Commercial Wiring Standard
applies to premises with more than four telephone lines. This draft has also been
reviewed and released by ANSI and TIA committees. At time of printing, the
standards are undergoing major revisions and are currently up for ballot.
We’re the “Standards” People
Because Leviton is an active participant in the formation of North American codes
and standards, you can be assured that our product development activities fully
support this emerging standards environment. In fact. we have prepared several
publications which describe standard practices and provide installation guidelines for
contractors. Many Leviton distributors also sponsor training programs dealing with
telecom wiring. And, of course, Leviton’s Applications Engineering Group is always
ready to assist you with any questions you may have about standards and codes,
standard practices, or any installation problem.

RJ21X
Mechanical Arrangement
Circuits are provided on numbered tip and ring positions on a miniature 50-pin ribbon connector (Amphenol-type). Pins 1 (ring) and 26 (tip) are considered position 1.
Pins 2 (ring) and 27 (tip) of the ribbon connector are position 2. This pairing continues through twenty-five pairs.
Typical Usage
Many key and PBX systems specify the RJ21X, or ‘Amphenol-type’ as the network
interface device. Many of these systems also use the RJ21X as a connector for stations or telephone sets, wired from the KSU or PBX Main Distribution Frame.
Note: Sometimes an RJ11 or RJ14C can be installed in place of an RJ21X. While
many smaller systems that require only a few lines may show the RJ21X as
the ‘official’ jack required under registration, less complex jacks such as the
RJ11 or RJ14C can often be specified (perhaps in multiples). If the system
requires only a few lines but the RJ21X is specified on the registration label,
under FCC Part 68 you may specify the RJ11C, RJ14C, RJ25C, or RJ61X instead.
Many Leviton jacks can be used for the RJ21X configuration where
‘intermixing’ is permitted. Substitution of these special jacks is often both
economical and practical. Contact Leviton Network Solutions Division for information about versions to meet your requirements.

NO! Aluminum wire tends to oxidize over time, and the oxide layer does not
conduct electricity. This results in a poor connection with the wiring device terminal
screws, particularly if they are steel. The connections gradually heat up to the point
where fires are started inside the walls. For this reason, all standard wiring devices
contain the warning, “For use with copper or copper-clad wire ONLY. Do not use with
aluminum wire.” The only exception to this is CO/ALR wiring devices.

incandescent dimmer?
Because of the way all dimmers deliver power at settings other than full
brightness, the filaments inside a light bulb may vibrate when lighting is dimmed.
This filament vibration causes the hum. To silence the fixture, a slight change in
the brightness setting will usually eliminate bulb noise. The most effective way
to quiet the fixture is to replace the light bulb.
t*TJUOPSNBMGPSBEJNNFSUPGFFMXBSNXIFOJOVTF
In service, it is normal for dimmers to feel warm to the touch: it is completely
acceptable as long as the temperatures remain within the limits established by
UL and the manufacturer. Underwriters Laboratories (UL) has specified limiting
parameters for this type of heat buildup. The average dimmer operates at
approximately 140°F; UL allows a maximum temperature of 195°F. When
dimmers are ganged together, each dimmer’s load must be derated to offset
the resulting heat build-up from the presence of several units in the same wallbox.

parameters for this type of heat buildup. The average dimmer operates at
approximately 140°F; UL allows a maximum temperature of 195°F. When dimmers are ganged together, each dimmer’s load must be derated to offset the
resulting heat build-up from the presence of several units in the same wallbox.

FREQUENTLY ASKED QUESTIONS
GFCI FAQs
t8IBUJTB('$*
A GFCI is a receptacle or outlet designed to protect people from hazardous
ground faults. A ground fault occurs when electrical current travels through any
abnormal path to ground, which can be dangerous if the current travels through
a person. This can happen when any appliance plugged into an outlet becomes
damaged. Electrical current “leaking” from the faulty appliance can travel
through anyone touching it, especially in a wet environment, causing a serious
electrical shock.
t)PXEPFTB('$*XPSL
The GFCI monitors the flow of electricity from the outlet to any electrical device
plugged into it. If the GFCI detects that some current is not returning to the
receptacle, and is going out through another path, the GFCI will quickly turn off
power to the receptacle.
t8IFSFBSF('$*TSFRVJSFE
GFCIs (Ground Fault Circuit Interrupters) are required in many locations,
particularly where water and electricity may meet. The NEC (National Electrical
Code) requires GFCIs in kitchens, bathrooms, garages and outdoor locations.
t)PXNBOZSFDFQUBDMFTDBOCFJOTUBMMFEBOEQSPUFDUFEJOB
residential application on the load side of a SmartLockPro® GFCI?
There is no limit as far as the number of receptacles that can be protected from
the load side of the GFCI. Since our GFCIs are rated for 20 Amp feed-through they
are capable of protecting a whole residential 20 Amp circuit.
t8IBUEPFT$MBTT"NFBOXIFOBQQMJFEUPB('$*
Class A is an interrupter that will interrupt the circuit to the load when the
ground-fault current is 6 mA or more but not when the ground-fault current is
4 mA or less.
t8IBUJT-JOF-PBESFWFSTBM
When the line and load leads are reversed (below), the GFCI receptacle face is
now wired directly to the power coming from the panel, completely bypassing
the internal switching mechanism. The face is not GFCI protected and remains
live even after the internal switch opens. This is a potentially hazardous
condition, and the fact that the device appears to be operating properly creates
a false sense of protection for end-users. UL now requires a diagnostic indication
to alert installers that there is a line/load reversal.
t8IBUEPFT-FWJUPOT4NBSU-PDL130® GFCI protection provide?
If a SmartLockPRO® GFCI is miswired during installation (line-load reversal), it
cannot be reset, blocking delivery of power to its feed-through terminals and
face. The GFCI is completely dead and the green LED will be ON to indicate a
line-load reversal. Once the GFCI is wired properly and the unit can be reset, the
LED acts as a power indicator that remains ON as long as the GFCI is operating
correctly and providing power.
-The SmartLockPRO® GFCI features Leviton’s unique patented lockout action
as an end-of-life indication. If a SmartLockPRO® GFCI is damaged so that it
cannot respond properly to a ground fault, the GFCI prevents reset.
t$BOB('$*CFVTFEPVUEPPST
Yes, only if the GFCI meets the UL 498 requirements for weather-resistant
receptacles. Also, covers must be used with weather resistant GFCI receptacles
in damp or wet locations per Section 406.8 of the NEC code. Leviton’s W7599
and W7899 are both ideal for outdoor applications.
When the GFCI is wired correctly, power will be fed to the line side terminals,
through the internal switching mechanism to the GFCI receptacle face and any
downstream receptacles. When the internal switch opens, power is disconnected
from both the GFCI receptacle face and anything connected to load side terminals.
t$BO*VTFB('$*JOBXJSFVOHSPVOEFE
DJSDVJU Yes. Section 406.3(D)(3) of the 2008 National Electric Code permits a
non-grounding type receptacle to be replaced with a grounding type receptacle
without a grounding connection. However, the grounding receptacle must be
GFCI-protected. The diagram below shows a typical non-grounding (2-prong)
receptacle replaced with a GFCI. The GFCI must be marked, “No Equipment
Ground.” The GFCI can feed through to a grounding receptacle, which must be
marked “GFCI Protected. No Equipment Ground.” For increased electrical safety,
Leviton strongly recommends installing a GFCI in every non-grounding circuit. A
ground wire provides protection by offering a parallel path back to ground for any
fault current. Without a ground wire, fault current will try and take other paths to
ground and a GFCI will trip and cut power under these hazardous conditions.
Ground faults are more likely to occur in non-grounding circuits and a GFCI
will help protect family members from this potentially hazardous condition.

t$BO('$*T#F6TFEJO$JSDVJUTXJUIB4IBSFE/FVUSBM
Using a single neutral conductor for more than one circuit can be looked at as a
way to save money on wiring. Because a GFCI receptacle looks for a balance of
current flowing in a single hot conductor and a single neutral conductor, it will
not operate properly when more than one hot conductor is sharing a neutral
downstream from a GFCI. Current flowing in the neutral from the circuit not
protected by the GFCI will cause the GFCI to see an imbalance typically
associated with a ground fault and the GFCI will trip. A hazardous condition would
exist in the circuit not protected by the GFCI as it may appear as though the
power is off even though the hot leg is still live. In circuits wired this way, the
neutral needs to be split at or before reaching the GFCI receptacle and a
dedicated neutral must be run from the GFCI receptacle to all downstream
receptacles protected by the GFCI.
