Performing a Trip Test
Trip tests can only be performed with the Admin login to the overcurrent control. When
a Trip test is performed, the overcurrent control will send a signal to actuate the trip
solenoids in the switchgear, tripping the fault interrupters and opening the circuit.
NOTICE
Test tripping the overcurrent control will open the fault interrupter and may cause
unplanned loss of load.
The Test Trip menu contains eight trip modes:
Trip Mode: Three-Phase, Interrupter 1, All Phases
Trip Mode: Three-Phase, Interrupter 2, All Phases
Trip Mode: Single-Phase, Interrupter 1, Phase A
Trip Mode: Single-Phase, Interrupter 1, Phase B
Trip Mode: Single-Phase, Interrupter 1, Phase C
Trip Mode: Single-Phase, Interrupter 2, Phase A
Trip Mode: Single-Phase, Interrupter 2, Phase B
Trip Mode: Single-Phase, Interrupter 2, Phase C
