should comment that the Fluke tester will only give a max reading of 500MOhm when on 500V test - it could well be higher. It's a feature I like and dislike about the flukes - a quick way of seeing the test voltage (a new install should peg the tester), but does have a few issues with calculations for IR on large systems (remember its the installation not the circuit that has to be above 1MOhm or 20MOhm) And I agree, its a very pretty CU.
If you’ve got double switched lighting circuits you’ll need to test more than once, part of the circuit won’t be tested on the first test (strappers between switches) as the switch will be open on one conductor and closed on the other. So test, check results then operate the switch in the other position and test again ti catch the other conductor. Hope I’ve worded that clearly 😂
2 way lighting switches should be operated one at a time according to GN3.
nice and informative , the cu is also showing very level👍

Do you guys have a video, where you do the sequence of tests, with global ir etc.. this would help me massively, currently in year 3 doing testing
Noted 👍🏻
I thought you leave circuit breakers on when doing IR? Genuine question mint video as always
He is testing circuits separately as he cannot do an all in one IR test due to the presence of RCD devices
Off topic : are SY glands different to SWA glands
Yes SY glands have 2 slits in it for the braiding to sit in
If smoke alarms are wired in should they be disconnected?
Yes
Sorry if i sound thick i didn't get the strappers bit.

@noskills9577 thank you that makes sense.
Thax boss
Thanks for watching and commenting 👍🏻
Cool.
