Yes. It is possible to trace a fault without disconnecting the battery ground monitor. To do this first take a measurement of the fault current out of the transmitter. Do this by placing the receiver CT around the appropriate output cable of the transmitter. Note the real fault current, as read on the receiver. This will be on the top display. Now place the CT around the earth connection of the ground fault monitor. Note the real current, as shown on the receivers top display. The difference between these 2 values will be the current being drawn by the real fault. Search for this current in the circuits in the panel. Be sure to use the sync cable for all of these measurements. This will ensure you are seeing only real fault current and not stray leakage current. NOTE: When you cannot isolate the earth connection from battery ground fault monitor it is recommended not to use the alarm feature of the receiver. Instead view the actual readings on the receiver.
