INTRODUCTION
This installation instruction is for General Electric SCH cable operating mechanisms. These mechanisms are for circuit breakers
mounted in Hoffman disconnect enclosures.
INSTALLATION STEPS
Step 1
Install operating plate (item1) and plate gasket (item 2) on the inside of the enclosure, behind the rectangular opening provided.
Gasket side with PSA should be attached to the adapter plate. Secure in place with four screws (item 3) and four nylon washers
(item 14).
Step 2
Assemble the General Electric SCH operating handle and cable adapter to the mounting plate which was installed in the enclosure
in step 1. Omit cap screw and lockwasher which fits into bottom hole of G.E. operating andle. Also omit G.E. stiffening bracket
which is not required.
Step 3
Install the slide arm (item 4) over the interlock part of the G.E. operating handle as shown. Note the the notch in the slide arm
is positioned toward the door opening. Place the smaller diameter end of the shoulder collar (item 5) through the oval slot in
the slide arm. Install long cap screw (item 6) with lockwasher (item 7) through shoulder collar into the bottom mounting hole
of the G.E. operating handle and tighten. The slide arm should move up and down smoothly. Install G.E. interlock blade per G.E.
instructions.
Step 4
Attach the bottom of the slide arm (item 4) to the offset arm of the lock release mechanism. Use two flat washer (item 8), two
lockwashers (item 9), and two hex nuts (item 10). Do not tighten until parts are adjusted (see step 5B).
Step 5
The handle safety lock release mechanism is adjustable.
(A) Check the adjustment of the factory installed roller bracket on enclosures with disconnect on right flange. The door
latch should hit against the latch stop portion of the roller bracket when the door is closed and latched. Adjust up or down
if necessary. The attached mechanism will then provide the necessary up−down motion required to operate the release
mechanism.
(B) Adjust the length of the slide arm assembly. With proper adjustment of the slide arm, the safety lock (on G.E. handle
operator) should release just before the master door is fully latched. Lengthen slide arm if safety lock releases too soon.
Shorten slide arm if safety lock releases too late.
Step 6
Attach the door catch (item 11), provided by Hoffman, to the tapped spacer on the door using the bottom set of mounting
holes. Use two screws (item 12) and lockwashers (item 13). The door catch prevents the door from being opened when the G.E.
operating handle is in the “ON” position.
Step 7
Drill and tap holes in panel per General Electric instructions. See General Electric instructions for locating holes within range of
cable length being used.
Step 8
Install panel in enclosure.
Step 9
Mount circuit breaker and cable operating mechanism on panel using General Electric instructions and parts.
