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

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
