External Earth Fault Loop Impedance Ze Test - How to Remove Parallel Earth Paths - Live Testing In this video me and Marcus show how to carryout an external earth fault loop impedance test on a single phase installation. All stage of this live test are demonstrated as well as the importance of removing parallel earth path created by incoming metal pipework such as the water and gas. This video is designed to help learners with testing and fault finding units in City and Guilds and EAL qualificat

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
