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

3 Phase External Earth Fault Loop Impedance Test Live testing for external earth fault loop impedance on a 3 phase supply. This test is demonstrated on a live 3 phase distribution board and will help with AM2 and AM2S exams. As always preparing for your end skills test AM2, AM2S or AM2E requires time testing at college and on-site experience of testing electrical circuits. NOTE - Your end point assessment AM2 and AM2S will require you to have the main switch locked off, sign in place and key In

Total Earth Fault Loop Impedance How to calculate or measure total earth fault loop impedance for an installation connected to a TN-S earthing arrangements. In this video I show drawings to aid with City and Guilds and EAL electrical exams at level 1, 2 and 3. The total earth fault loop impedance Zs of a circuit is made up for the impedance of the supply authorities cable Ze and the circuit impedance of the line conductor R1 and the circuit protective conductor (CPC) impedance R2. So total earth

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. Videos are training aids for City and Guilds (C and G) and EAL courses Level 1, 2 and 3.
