    R1&R2 and Insulation Resistance Test with fixed appliances

    Can anyone help me, I've been asked to do an inspection on a property that is on a single 32A ring, including the kitchen. The appliances are all integrated and aren't spurs. Is there a way to perform the test with these appliances in place? Thanks!

    Insulation Resistance Test with Fluke 1652

    I'm using a Fluke 1652c as my MFT. When I do the Insulation resistance tests at 500v - sometimes the result is displayed immediatley i.e >500 Megohms , other times the resistance seems to climb slowly, peaking around a figure. As this figure is generally massively in excess of the required 2...

    Insulation Resistance test ADVICE PLEASE

    I have just carried out an IR test on a cooker circuit using my FLUKE1653b tester. Got a reading of >500m ohms for the L/L test but only 5.77m ohms for the L/E test. As a result of this I split the Line and Neutral and did a Line/Earth test and got >500m ohms and a Neutral/Earth and again only...

    insulation resistance test

    How do you undertake insulation resistance test on "singles" ? Because they are not encased in a sheath like T&E how does the test equipment measure between them?

    insulation resistance test on equipment with high earth leakage

    Hi guys. This is to do with Periodic Inspections. When you are testing a circuit and forget to unplug a piece of equipment that has a high earth leakage could this be damaged doing the ins res test between live and earth. I do not know electronics but is there a connection to earth. The problem...

    Insulation Resistance Test

    Hi all, When performing an IR test, you are advised to remove all sensitive equipment, i.e. dimmers etc. My question is, do you leave the conductors open ended, do test and replace. What if you crunch it when replacing it. That makes it a waste of time doing the test in the first place. Isn't...

    insulation resistance test

    hi, just want to confirm I have got this right. If I am doing a insulation resistance test on a ring circuit and it has fixed equipment then a soft test at 250v is required and the socket switches in the on position. cheers

    Insulation Resistance Test

    Any feedback on this would be handy. If you have a property that has a lot of lamps etc.. that are too much to remove to carry out a insulation resistance test why does it work that connecting the line and neutral together and testing between the two and earth. Can someone explain.
