When inspecting the operating mechanism of an air circuit breaker:
- Inspect for loose, broken, worn, or missing parts (refer to the manufacturer’s schematic for any needed parts).
- Examine the moving parts for excessive wear. Ensure that operating mechanisms are functioning correctly (no binding, hanging or delayed action).
- Make sure that lubrication is done in accordance to the manufacturer’s specs.
- Ensure that mechanisms are cleaned, correctly lubricated, and that all bolts and screws are secured properly. Repair or replace as needed.
