    Max continuity reading for bonding

    Good evening I was always taught the gas and water bonds should have a continuity ideally with a maximum of 0.05 ohms, is this a exact maximum or a rule of thumb and if it was higher than this what coding would we give it? I had a look through the codebreakers booklet but could not bit see an...

    PIR Continuity

    I bought a PIR for an installation the other day and I was intending to use it for a contact but as soon as power is applied the live and switched live have continuity whether the PIR is triggered or not, I’ve tested a couple of different PIRs already installed and this doesn’t seem to be the...

    Continuity line-earth

    This may seem a simple problem but I'm racking my brains here. Doing some fault finding on some contractors that supply some panel heaters. I thought I'd do a simple r1+r2 test to find out which contactor supplys the specific heater that I was working on. Problem is, all the lines on the...

    Do you test the continuity of an installations main incoming earth

    This may seem like a stupid question but when testing for continuity using the long lead method I know you test the water and gas bonds etc but do you test the incoming earthing cable. I ask this because reading guidance note 3 it talks about the earthing conductor to be tested and I am slightly...

    Ring main continuity test

    I'm not sure if this is a reasonable question or so stupid it shouldn't be asked. If the latter than I apologise and hope I don't get too much negativity back. So I want to perform the test Continuity of ring final conductors on an existing ring main. Because I'm lazy and its dark outside...

    Earth Continuity Testing

    As part of my new job, we are required to test existing DC Power Racks for Telecoms. We are told to carry out a earth continuity test, then a IR test, then a ELI test. I may be getting a little complacent the older I get, but surely Earth Continuity is slightly OTT? I mean, we're proving an...

    Question regarding signing off 32a ring circuit with broken CPC ring continuity

    I installed a kitchen ring recently. Went back to test after the builders had finished and found that the CPC is broken somewhere inaccessible, everything else tests normal. I’ve got continuity on live conductors, and even with the broken CPC, each socket is connected to the CPC and tests with...
