Things You Should Know
What are power surges and spikes?
Surges and spikes are temporary and instantaneous events
that increase “normal” electrical line voltage, and can cause
serious damage to sensitive equipment.
Conventional fuses and breakers do not guard against
surges.
What causes surges and spikes?
Lightning - a direct hit is usually catastrophic.
Proximity Strikes - lightning strikes several miles away
causing large voltage spikes along transmission lines.
Brownouts / Blackouts - under-voltage or sag that’s
immediately followed by an unusually high voltage transient.
If your lights flicker or dim, it’s usually an indication that a
brownout occurred.
Utility Grid Switching - utility companies switching
transmission lines from one supply system to another.
Inductive Loads - the switching on and off of electric motors
inside or outside a facility (for example air conditioners or
heavy machinery).
The effects of surges and spikes are the three D’s:
Degradation - gradual deterioration of internal circuitry from
repeated power surges.
Destruction - resulting in expensive equipment replacement
costs.
Downtime - the most costly effect - can result in lost
productivity or lost customers.
The payback for investing in quality surge protection is:
Reduced downtime
Extended equipment life
Increased Customer Satisfaction
What equipment should be protected against
power surges?
Surges can be present on any metallic conductor, including
utility power lines, telephone lines, computer data lines, and
CCTV/CATV cable feeds. Therefore surge protection
should be installed on all circuits within a system.

Network Surge Protection Basics
IP/PoE Networks
To keep surges from entering your building and your network, you must provide a layer of protection. This head-end
protection point is the only way to reduce the risk associated with metallic conductors connecting external devices to
internal network components. In addition, externally mounted devices should be protected from surges that are
introduced on the same metallic conductors.
It is also recommended to install an Uninterruptible Power Supply (UPS). A UPS provides consistent backup power
during inconsistent power quality issues. Not only will it protect your hardware investment, it prevents data loss.
Failure to install surge protective devices (SPD’s) and UPS systems places all internal network connected equipment
at risk.

Rules for Proper Grounding
The use of a grounding bar is strongly recommended as a means of terminating SPD ground wires to existing electrical
grounding leads. This will ensure a solid mechanical connection of all grounding wires.
The use of twist-on wire connectors (“wire nuts”) is not recommended for termination of SPD ground wires to existing
electrical leads. Twist-on wire connectors may become loose and/or corroded over time, can cause increased ground
resistance, and can also unnecessarily extend the length of the grounding conductor. This would degrade the
performance of the SPD due to the lack of a short, low impedance ground path.
When installing multiple Surge Protective Devices (SPD's) and terminating to a common ground, a dedicated ground
wire running from each individual SPD to a common grounding bus bar is strongly recommended. “Daisy-chaining”
multiple SPD ground wires together via the SPD grounding terminals, or by using twist-on wire connectors is not
recommended as this increases the resistance and extends the length of the ground path.
