every youtube channel my tutors have recommended have had absolutely insufferable grating voices for the narration, and a monotone explanation that is impossible for any autistic person to listen to. thank you two sooooooooo much for actually speaking like normal human beings in your vids so i can actually process the words you're saying

I'm not a electrician but mess with electronics, these videos always show how to test for fault finding and I've learned alot from watching these great videos on YouTube.
Thanks for all you trademarks who show your skills to others because I've learned watching someone showing there trade rather than reading a trade

Great help and refresh thanks, especially with my lvl3 live/dead testing and fault finding assessment tomorrow (having been waiting, and out of the loop, since April).

If it is lighting and as you say split the circuit mid point and the leg coming from the board is clear i connect back up then youv got lighting to some of the property while you find the fault on the other leg, usefull if its getting dark at least theyl be light coming in same on a Ring main lets say split mid way whichever leg is clear bang back in the breaker at the board temporarily gets half the sockets on 👍 great videos these

As an adult learner anything on fault finding is a great help. Coincidentally, I've been watching JW's videos on "borrowed neutrals" so a future video on how to find one using IR would be great. Thanks again for the video.
