Prospective Fault Current PSCC, PEFC, PFC and External Earth Fault Loop Impedance Ze - Live Tests

In this video Marcus carries out using the 2 lead high setting on his Megger MFT tester the external earth fault loop impedance (Ze) and prospective fault current tests. These live tests are carried out from inside the consumer unit (fuse board or fuse box) and will confirm the incoming supply has a connection to Earth and that the overcurrent protective devices can withstand the possible high levels of fault current. == 🕐 Time Stamps - Cut to the action 🕕 == 00:00 - External earth fault loop impedance and PSC tests 00:16 - 2 lead high test trips the RCD 00:28 - 2 lead high setting on our Megger MFT tester 00:52 - Disconnected earthing conductor 02:01 - The whole installation is off 02:19 - Ze reading 02:24 - Maximum Ze for TN-C-S and TN-S earthing systems 02:45 - Prospective earth fault current test 03:29 - Prospective short circuit current test 04:21 - Record the highest reading Ipf Videos are training aids for City and Guilds (C and G) and EAL courses Level 1, 2, 3 plus AM2, AM2S and AM2E.
