    EICR coding twin and earth tails/riser

    Not unusual in townhouses that have been converted into flats round here to see all the meters in the basement, each feeding a switched fuse spur that then feeds 16mm T+E to each flat. Obviously that's a run of tens of metres, concealed in walls etc with no RCD protection. Guessing it was...

    EICR Coding Confusion wrt Supplementary Bonding

    Yes, it's another EICR coding question - hurrah! :blush: Inspecting a small 1 bed 70s ex-council flat that was going well. Main Bonding had been put in place in advance and most of the tests were as perfect as you could get. Seriously, if you wanted to set up a 'perfect' test rig I don't...

    Non fire rated downlights and EICR coding&

    Good evening, I am just wondering whether or not non fire rated downlights should be a coded issue (c3 as many electricians have told me) or whether this is false. From memory I believe napit code breakers made it a c3 if there was a room above. P.s I'm still learning and this just seems to...

    4293 elcb coding __________

    Been called to a job for a second opinion, Previous spark said current db set up would warrant a code 2 and therefore need a board change. Granted the elcb set up isn't great for discrimination but cant see this warranting more than a C3. But what about the elcb itself? It Tests out fine. Any...
