    Two test leads, one port

    Hoping someone might be able to help. I’ve seen an ‘adaptor’ that allows 2 test leads to run from one port of an MFT (doing IR test). But, can’t find anywhere to buy it. Anyone know where I could get one from?

    OK, Stop laughing at the back! SO, I'm house hunting and, ignoring the number of beautifully decorated houses with shite electrics - I also want to be aware of any damp issues. This led me to try using the trusty Megger with sharp probes to test for damp. This appears to work, or at-least is...

    Annual emergency light test

    I replaced the emergency lights in a small block of flats about 6 months ago, but the last time I did a 3 hour emergency light test was a year ago. Common sense says that I don't need to test the new emergency lights until they are a year old, but any clarification appreciated?

    Okay may be a thick question but I have an RCD tripping on 5 x test 180 at 40ms. Pass or fail? GN3 says must not exceed 40ms BBB says within 40ms My tester says computer says no.

    Commercial Multiple Earth Electrodes Test Results

    I need to clarify something that's rattling around in my head. I was taught when testing lightning protection systems that the maximum permissible combined electrode readings shouldn't be over 10 ohms. So we would test all the electrodes individually then work out resistance in parallel. We...

    When testing a circuit protected by RCBO, do you test at the DB or furtherst point

    Hi, I just have a few questions in regards to testing an RCBO circuit Is there a requirement to test at either the furthest point or the DB or is it down to the testers discretion. Do the test results differ? What tests on a circuit will trip the RCBO when you are away from the DB. Is it...
