Circuit Breaker Replacement

Any existing circuit breaker may be field-replaced with an identical circuit breaker or with a
breaker that has a different current rating or time delay. However, a breaker with a higher
current rating may only be used as a replacement if the total current draw of the affected bus
will not exceed 100 Amps. A circuit breaker mounting position that does not have an existing
breaker (blank) cannot be used for installation of a replacement breaker. Use the following
procedure to replace an existing circuit breaker with a new breaker: 

1. Turn-off or disconnect the power from the power bus (either A or B) that supplies current

to the circuit breaker to be replaced. 

2. Insert a flat-bladed screwdriver into the slot 

above

 the circuit breaker as shown in

Figure 18

. 

3. Push down and forward on the upper circuit breaker lock tab until the 

top

 of the circuit

breaker is released from the panel. 

4. Hold the top edge of the circuit breaker to keep the circuit breaker from snapping back into

the panel when the screwdriver is withdrawn from the slot. 

5. Insert a flat-bladed screwdriver into the slot 

below

 the circuit breaker. 

6. Push down and forward on the lower circuit breaker lock tab until the bottom of the circuit

breaker is released from the panel. 

7. Pull the circuit breaker forward and out of the panel to expose the wiring connections on

the rear side of the circuit breaker. 

Note: 

Previous versions of the Select Series Circuit Breaker Panel were not equipped with

field-replaceable circuit breakers. If the panel does not have slots above the circuit
breakers as shown in 

Figure 18

, then it does not have field-replacable circuit breakers and

this procedure does not apply. 

Danger: 

During normal operation, the terminal connections on the circuit breakers are

electrically energized. Failure to disconnect the power from the power bus that supplies current
to the circuit breaker being replaced may cause severe personal injury to the installer and/or
equipment damage.
