Tighten Detent Screws
B. Secure the cable (16) to the frame assembly (4) by placing
it between the cable retainer clip (26) and the shim (27),
secure with two #10-32 x 3/8 in. screws and lockwashers.
NOTE: Detent (28) in cable retainer must align with the
groove (29) in the cable’s metal fitting (Figure 7).
Securing Operating Cable to Circuit Breaker
NOTE: Before attaching the cable to the circuit breaker,
installers must confirm that the power from the supply
source has been de-energized.
A. Move the circuit breaker handle to the ON position
B. Remove the soft plastic cap from the end of the threaded
cable rod (30) and slide the rod through the hole in the
sliding plate tab (31) of the circuit breaker operating
mechanism (22) (Figure 8).
C. Move the flange mount operating handle (2) to its maxi-
mum ON position and hold it in place.
D. Place the cable mounting threads (30) into the slot on the
fixed plate tab (32) so that the two mounting nuts (33) are
on both sides of the tab. Adjust the two mounting nuts so
that the #10-32 nut on the cable rod just touches the
sliding plate tab (31). Tighten the mounting nuts (33) to
secure the cable (Figure 8).
E. Continue holding the operating handle in the ON position
and place the spring (34) over the end of the rod. Screw
on the spring adjuster (35) and tighten until it begins to
compress the spring. Do not overtighten.
Making Cable Adjustments
A. Check that circuit breaker turns OFF and ON by moving
the operating handle (2) up for ON and down for OFF If the
breaker does not switch ON, loosen the cable mounting
nuts (29) at the fixed plate tab (28), hold the operating
handle in the maximum ON position, and move the cable
(16) toward the top of the breaker. Retighten the mount-
ing nuts (29) to secure.
B. Trip the circuit breaker by pressing the PUSH TO TRIP
button on the front of the circuit breaker.
C. Check that circuit breaker resets by moving the operating
handle (2) from ON to OFF and back to ON. If the breaker
resets, tighten the spring adjuster (31) one additional
turn. Attach the lockwasher and #10-32 locknut (32) to
the end of the cable rod, and tighten the locknut.
D. If the circuit breaker does not reset after Step B, tighten
the spring adjuster (35) one turn and repeat Step B.
Continue this procedure until the breaker does reset,
then tighten the adjuster spring one additional turn.
Secure with the lockwasher and locknut (36).
