Hazardous procedures
In addition to other procedures described in

personnel must adhere to the following:
1. Always work only on de-energized
equipment. Always de-energize a circuit
breaker or ground and test device and
remove it from the switchgear before
performing any tests, maintenance or
repair.
2. Always perform maintenance on the
circuit breaker or ground and test device
after the spring-charged mechanisms

certain that the indicator flags read

mechanism perform its function without
forcing or defeating the device.
