Earth Fault Loop Impedance (Zs) - Testing 16 Amp Industrial Socket Outlets Both Single and 3 Phase Electrician Matt is carrying out an earth fault loop impedance testing (sometimes called the Zs test) on a 16 amp single phase and a 16 amp 3 phase industrial socket outlet (sometimes call a commando socket). This video Matt shows how to carry out the tests as well as the plugs and leads Matt has made up to make this test easier but your thoughts on if it’s safer are VERY welcome... As always prepa

Total Earth Fault Loop Impedance Zs = Ze R1 R2 for TN-S and TN-C-S Earthing Arrangements How to calculate or measure total earth fault loop impedance for an installation connected to a TN-S and TN-C-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

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

Earth Fault Loop Impedance Zs 100% or 80% Values On Site With Matt. Calculations Using BS 7671 Matt take at look at both the Wiring Regulation BS 7671 and the On-Site Guide to show how both the 100% value and the 80% for a circuits maximum earth fault loop impedance is calculated. Great effort Matt with no kit to produce a video to help your learners in these difficult times 👍. Videos are training aids for City and Guilds (C and G) and EAL courses Level 1, 2, 3 plus AM2 and AM2S. Videos are tra

🛑 STOP Tripping the RCD - Earth Fault Loop Impedance Test EAL Awards City & Guilds SparkSafe In this video Marcus explains why we set our MFT tester to 3 lead low and not 2 lead high 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 impedance...
