Resetting the Button-Type Circuit Breaker
Your button-type circuit breakers may look slightly different from the
images shown in this section, but the reset procedure remains the same.
To reset the button-type breakers:
1. Locate the breaker whose ON button is up, indicating the breaker has
tripped.
2. Examine your Dominion PX device and the connected equipment to
remove or resolve the cause that results in the overload or short
circuit.
This step is required, or you cannot proceed with the next
step.
3. Press the ON button until it is completely down.
Resetting the Handle-Type Circuit Breaker
Your handle-type circuit breakers may look slightly different from the
images shown in this section, but the reset procedure remains the same.
To reset the handle-type breakers:
1. Lift the hinged cover over the breaker.
2. Check if the colorful rectangle or triangle below the operating handle is
GREEN, indicating the breaker has tripped.
