15.4Short Circuits

Normally, the overcurrent protective device on the circuit will prevent any electrical damage except at the actual point of short-circuit. A thorough inspection of the entire system after any large fault current should be made to ensure that there has been no mechanical damage to conductors, insulation, or equipment.

In addition, the individual overcurrent protective device or devices which performed the short-circuit interruption must be inspected for possible arcing damage to contacts, arc chutes and/or insulation.

15.5Circuit Breakers

Refer to General Electric Document GEH---6271, Installation Instructions for PowerBreakII Circuit Breakers/DrawOut 800 ---4000 Ampere Frames, for recommended circuit breaker maintenance.
