Equipment Ground-Fault Trip Functions Testing
Test Equipment Ground-Fault Trip Function |
Paragraph 230-95 (c) of the National Electrical Code requires that all equipment ground-fault protection systems be tested when first installed.
With the trip unit powered and the circuit breaker closed, test the equipment ground-fault (MicroLogic 6.0P trip unit) trip function.
The trip unit is powered if:
-
circuit breaker is on and has more than 150 V of load voltage on two phases (circuit breaker is closed or bottom fed).
-
the Full-Function or Hand-Held Test Kit is connected and on.
-
the 24 Vdc external power supply is connected.
-
an external voltage tap is installed and voltage of more than 150 V is present on two phases.
For instructions on how to close circuit breaker, refer to the circuit breaker installation instructions shipped with the circuit breaker.
To test trip function, press the ground-fault test button (A). Circuit breaker should trip.
If circuit breaker does not trip, contact the local field office.
