Insulation Resistance 

You just make more confusion.. You tell to do something and you don't do it.. From 0:55 to 2:15 what are you testing?? And why do you tell to disconnect the phase from the main and it is still connected? What are you measuring outside? Where that cables came from?

Turn it ooorrrrf

Thankyou sir

Thanks Bernie. Brilliant presentation.

If you are not dIsconnecting dimmers and sensor's, in the entire installation test. Are you still 500 volt mega testing the cables then. Or just regular ohm resistance testing the cables? Thanks

Who wired that board? Looks like a rats nest!!!

Holy shit, this isnt a joke, he's wearing non conductive yellow slip-ons over his non conductive shoes😂😂😂
