    Very low IR results on oven?

    I have just been carrying out an EICR and I have got some results that I am unsure about. The property has 2 ovens on the same circuit, the circuit has a line-earth IR of 0.004Mohms when the cooker isolation switch of one of the ovens (oven 1) is closed, and 0.4Mohms when the other cooker...

    EICRs: observations and test results that dismay me

    Eh up :) I don't do EICRs - not enough experience - but the things I see on some reports done by others really dismay me. Perhaps some of my understanding needs improving, I dunno. Or perhaps the CPSes have their own set of guidelines different from the sources I use? In the examples below, I'm...

    Lucien Nunes - Results of IR tests on equipment

    Hi Lucian. I hope you see this post that I said I was going to put up in response to your information. After what you said about being surprised about such a low resistance with equipment and because I hadn't given this too much thought, I had only assumed that some equipment had very low IR I...

    Exam results - should I appeal?

    Hi, I just got my 2365 exam results and certificates in the post. I passed, with distinctions for 202, 203 and 501, and 80-90% for everything else except the practical assessment, for which I got a Pass. Perhaps I didn't deserve anything more than a straight pass, but some things are bothering...

    Tripping RCD advice

    Hi! Need to pick some brains as I am truly stumped by this one call out to a flat with nuisance tripping. On arrival tested circuits and all IR tests between LE were coming up relatively low, between 0.50-0.80 with the exception of ring main coming out as 0.01. There has recently been a leak...
