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.
