External Earth Fault Loop Impedance Ze Test - How to Remove Parallel Earth Paths - Live Testing

Earth Fault Loop Impedance Test - 3 Lead Low or 2 Lead High - Test Explained In this video Marcus explains what happens when we would set our MFT tester to 3 lead low, 2 lead high and even 2 lead low in order to carryout an earth fault loop impedance on a circuit that has RCD protection. So we can carryout a earth fault loop impedance test it is important to select the correct setting on an MFT tester but do you understand why we often select 3 lead low setting when testing for earth fault loop

Don’t Tip the RCD When Preforming Earth Fault Loop Impedance Test In this short video we look at carrying out both the 2 and 3 lead Earth fault loop impedance test and explain why one doesn’t trip the RCD.
