Student trading aid for testing for external earth fault loop impedance Ze and PFC tests. Please note this test is carried out live under controlled conditions and all relevant safety precautions are in place. Includes a full demonstration on how to carry out an external earth fault loop impedance, PFC, PEFC and PSCC tests of a domestic single phase installation in the real world.
Please note the incoming protective device (fuse either 60, 80 or 100 amps) has a maximum PFC of between 16 and 33kA depending on its type.
