Cable Installation-SE, SF, SG
WARNING: Before installing any accessories, turn the
breaker off, disconnect it from all voltage sources, and
discharge the closing springs.
Use the following procedure to first install one end of the
operating cable to the interface mechanism, then the other
end to the breaker operating mechanism.
1. Slide a
7 / 16 -20 hex nut onto the end of the cable with
the #10-32 x 7 / 8 " thread. Install the nut onto the
threaded cable shank beyond the groove at the middle
of the shank. Install a
7 / 16 " lock washer onto the hex
nut. Do not tighten.
2. Place the operating handle in the OFF position. Slide
a washer, a spring, a second washer, and thread two
#10-32 hex nuts on #10-32 x 7/8” thread. Ensure the
spring is between two washers. Set the nuts to 3/8
inches (SE, and SF) and 7/16 inches for SG onto the
thread end of the cable as shown in Figure 4. Rotate
the pivot bracket into position as shown in Figure 1 &
Figure 4. Insert the end of the cable through the pivot
bracket, thread two #10-32 hex nuts and tighten until
it is snug. Insert the groove of the cable into the slot on
the base plate. Tighten the
7 / 16 " hex nut against the
cable operating mechanism base plate assembly until
it is snug.
3. Slide a 7 / 16 -20 hex nut over the cable end with the
#10-32 x 3" thread. Install the nut onto the threaded
cable shank beyond the groove at the middle of the
shank. Install a
7 / 16 " lock washer onto the hex nut.
Thread two #10-32 hex nuts approximately 2 3 / 4 ” onto
the threaded end of the cable. Rotate the pivot bracket
into position, as shown in Figure 4, and insert the end
of the cable through the pivot bracket. Insert the
groove of the cable into the slot on the base plate.
Tighten the
7 / 16 -20 hex nut against the base plate
flange until snug. With the breaker in the OFF
position, move the #10-32 hex nut up on the cable
shaft against the pivot bracket. Note the position of the
pivot bracket in Figure 4.
4. Verify that the power to the circuit breaker has been
turned off. Move the operating handle on the circuit
breaker to the ON position. Place the spring over the
cable end. Thread the spring retainer onto the end of
the cable and tighten to the installed height of 1
7 / 16 ".
Do not over tighten the retainer.
5. Move the operating handle ON and then OFF. If the
breaker does not turn ON, then, with the handle in the
OFF position, adjust the #10-32 hex nut toward the
pivot bracket until the breaker turns ON.
6. Trip the circuit breaker by pushing the TRIP button.
Move the operating handle to the OFF/RESET
position, then to ON. If the breaker reset, lock both
#10-32 hex nuts against the pivot bracket. If the
breaker does not reset, adjust the # 10-32 hex nut away
from the pivot bracket until the breaker resets.
