In this Q&A video, we explain how to calculate Earth Fault Loop Impedance (Zs) for an electrical circuit step-by-step. Learn: ✅ What Earth Fault Loop Impedance is and why it matters. ✅ The components of the fault loop and how impedance affects circuit safety. ✅ How to apply BS7671 regulations and calculate Zs using Ze and (R1 R2). ✅ Real-world examples with a 50A Type B MCB and 10 mm² cable in a 9 kW boiler circuit. This video is part of our electrical design training series in collaboration wit

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

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
