How to Measure External Earth Fault Loop Impedance. This video demonstrates external earth fault loop impedance testing using the MFT Pro from Test Instrument Solutions. This live test confirms the integrity of the supplier's earthing system and sets a baseline for future inspections. Before testing, we’ll cover key considerations, including identifying the earthing arrangement, disconnecting parallel earth paths, and ensuring safety protocols are in place. Watch as we perform the test step-by-s

🛑 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...
