attaching a safety latch to the door interface panel, the safety latch configured to be attachable to the door interface panel and having a slot structured to receive a tab of the second handle operator.

4. The method of claim 3 , wherein the handle of the second handle operator comprises a defeater mechanism configured to disengage the tab from the safety latch while the circuit breaker is energized.

5. A circuit breaker replacement kit for a motor control center, the circuit breaker replacement kit comprising:

a standoff having

a first plurality of mounting holes corresponding to existing holes on a bucket of the motor control center, and

a second plurality of holes corresponding to holes on a replacement circuit breaker;

a door interface panel having a third plurality of holes corresponding to existing holes on a door of the motor control center, the door interface panel having an opening formed therein having a size and shape corresponding to a handle of a replacement handle operator associated with the replacement circuit breaker; and

a safety latch configured to be attachable to the door interface panel and having a slot structured to receive a tab of the replacement handle operator;

wherein the door and the bucket are configured to accommodate an existing circuit breaker having a rotational handle mechanism; and

wherein the handle of the replacement handle operator is not a rotational handle mechanism.

6. The circuit breaker replacement kit of claim 5 , wherein the standoff has a depth that results in a front face of the handle operator being substantially flush with the door when the standoff is installed in the bucket and the circuit breaker and handle operator are attached to the standoff.

7. The circuit breaker replacement kit of claim 5 , wherein the opening of the door interface panel has a rectangular shape.

8. The motor control center of claim 5 , wherein the tab is configured to slide into the slot of the safety latch in an on position, wherein the circuit breaker is energized.

9. The motor control center of claim 5 , wherein the tab is configured to slide out of the slot of the safety latch in an off position, wherein the circuit breaker is de-energized.

10. The motor control center of claim 5 , wherein the handle of the replacement handle operator comprises a defeater mechanism configured to disengage the tab from the safety latch while the circuit breaker is energized.

11. The circuit breaker replacement kit of claim 5 , wherein the standoff includes a side panel and a rear flange, wherein at least one of tile first plurality of holes is disposed in the side panel and at least one of the first plurality of holes is disposed in the rear flange.

12. The circuit breaker replacement kit of claim 11 , wherein the standoff includes a front panel, wherein the second plurality of holes are formed in the front panel.

13. A motor control center comprising:

a replacement circuit breaker;

a replacement handle operator attached to the replacement circuit breaker;

a door;

a bucket;

a standoff having a first plurality of mounting holes corresponding to holes on the bucket, the standoff being attached to the bucket via the first plurality of holes, and a second plurality of holes corresponding to holes on the replacement circuit breaker, the standoff being attached to the replacement circuit breaker via the second plurality of holes;

a door interface panel having a third plurality of holes corresponding to holes on the door, the door interface panel being attached to the door via the third plurality of holes, wherein tile door interface panel has an opening formed therein having a size and shape corresponding a handle of the replacement handle operator; and

a safety latch configured to be attachable to the door interface panel and having a slot structured to receive a tab of the replacement handle operator;

wherein the door and the bucket are configured to accommodate an existing circuit breaker having a rotational handle mechanism; and

wherein the handle of the replacement handle operator does not have a rotational handle mechanism.

14. The motor control center of claim 13 , wherein the standoff has a depth that results in a front face of the handle operator being substantially flush with the door when the standoff is installed in the bucket and the circuit breaker and handle operator are attached to the standoff.
