Testing of Circuit Breaker
1. Verify that the circuit breaker can be turned on by moving the defeater lever downward and moving the disconnect handle to the ON position.
2. If the circuit breaker does not turn on, loosen the (2) screws and adjust the toggle adjustment plates toward the line terminals until the circuit
breaker turns on when the disconnect handle is in the ON position. Tighten the (2) toggle adjustment plate screws to 25 - 30 lb-in.
3. If the circuit breaker still can not be turned on unhook the spring, remove hitch pin and separate threaded rod and handle link. Turn threaded rod
one full turn counterclockwise. Reattach threaded rod and handle link, hitch pin and spring. Repeat Step 1 and if necessary Step 2.
4. Verify that the circuit breaker can be turned off by moving the disconnect handle to the OFF position.
5. If the circuit breaker can not be turned off, loosen the (2) screws and adjust the toggle adjustment plates toward the load terminals until the
circuit breaker turns off when the disconnect handle is in the OFF position. Tighten the (2) toggle adjustment plate screws to 25 - 30 lb-in.
6. If the circuit breaker still can not be turned off and if no adjustment of the threaded rod was made in Step 3 then unhook the spring, separate
threaded rod and handle link and remove hitch pin. Turn threaded rod one full turn clockwise. Reattach threaded rod and handle link, hitch pin
and spring. Repeat Step 4 and if necessary Step 5.
7. Verify that the circuit breaker can be reset after manually tripping when circuit breaker is in the ON position.
8. Manually trip the circuit breaker while in the ON position, then move the disconnect handle to the Off-Reset position.
9. If the circuit breaker does not reset, loosen the (2) screws and adjust the toggle adjustment plates in small increments toward the load terminals.
Note: Repeat this procedure until the circuit breaker can be reset.
Note: Do not adjust the toggle adjustment plate too far: this will prevent the disconnect handle from moving to the full OFF-Reset position.
10.Tighten the (2) adjustment plate screws to 25 - 30 lb-in.
11.Verify that the circuit breaker can still be turned on following the above steps.
Note: Twisting of the bail mechanism is acceptable when the handle is in the full ON and full OFF position.
