WebThe first thing to do is to check your ground fault circuit interrupter to ensure no faults from it. To do that, you should check for the reset and trip buttons. Then push the reset button, because, in some cases, the failures could be with the switch, so check to see if it clicks and stays in place. You should also test it with a multimeter ... Web5.7 The equipment shall include a pulsing feature to assist in locating faults. The pulsing cycle shall be adjustable by the user. 5.8 The unit shall be capable of measuring the system charging current by shorting one phase directly to ground. This shall be interlocked with the fault detection system to prevent measurement during a ground fault.
