    I would like to get a better understanding of what the specific IR test results could indicate. I'm talking more about the below 1MΩ area. I'm talking about.. wet plaster, flooding (sitting in water), degraded insulation etc etc, I realise it wouldn't give the answer but it may help in narrowing...

    RCD tripping times at 1x and 5x

    I understand that when carrying out RCD testing an RCD should trip within 300ms at 1x and 40ms at 5x but is it common that on occasions for the RCD to trip quicker at 1x than 5x. I never had it occur personally. I am just looking at some old certs and on some circuits the RCD is tripping...

    Wondering the results.

    Came across this today, a 4mm cable terminated, but some of the strands had been cut in order for the cable to be terminated. Oddly, it was feeding a light.

    Trust your test results??

    Last week I investigated a 3036 fuse blowing on a radial - different IR on each end, no continuity on the CPC. So I left the circuit isolated. I pondered as to whether the ultra low IR was related to a new water main being installed about 3 months earlier! So I went in again today and found that...

    IR testing results on MWC

    Interested to know what other people do about IR testing results on a MWC. If your additions contain new fixed wiring then you test that and record those results, obviously.
