    EICR coding check?

    I have just completed an EICR. The lighting circuit has an earth leaving the CU, then some lights have 2 core going to them (L + N) and some twin and earth, no continuity of CPC even at the ones with an earth. There are some metal light fittings that require an earth and also metal screws in...

    EICR inaccurate coding

    Another accidental landlord, quite possibly another dodgy EICR? I instructed an electrician (Essex area) to perform an EICR at the house I rent out. His report is 'unsatisfactory'. He has included a C2 rating for downlights in the bathroom. The reason given is the lights are not IP/fire rated...

    EICR on TT, Coding for TP isolators and SP RCBOs

    Hello, I'm after some coding advice / opinions regarding EICR of warehouses / offices. In others opinion would this be agreeable (helplines closed at weekends..) The units are TT. Where there is 4 pole 300mA S main switch to DBs, but single pole RCBOs or MCBs are utilised within them, C3...

    Coding question - 8.5kw shower, B32

    How would you code this? A 8kw shower (so pulling ~37A) is protected by a B32 breaker. 6mm² cable rated at 47A, ref method C (Actually, that last bit isn't true. In fact it's currently ref 101 = 27A, but an easy fix to get it to ref C, so for the sake of the discussion, let's pretend it's...

    Coding questions

    Hi. This is a gloriously messy installation I looked at this morning at a house a friend just purchased. It t became quickly clear it was more economical to rewire than rectify. I will however be putting findings in writing and there are a couple of new situations for me. So here goes: My...

    EICR Coding query

    Hi all, I have recently carried out an EICR on a big house and am struggling with coding on quite a big issue. The main tails & earth's are connected into Henley blocks, then looped into 2 separate consumer units right next to the service head/meter etc. Then there is a 3rd set of tails which go...

    EICR coding for upside down accessories?

    Hi, I've gone in to a job as a 2nd opinion on a EICR done by a previous contractor. One of the issues was a C2 for an upside shower switch. It's a neon switch so although its not fitted right it's still obvious when it's on or off. I've got same issue on with an upside down socket outlet...

    Coding question

    Good morning all. How would you code the following?: 1 - Electric shower installed without RCD protection, where manufacturer states it is required? Supplementary bonding present. Normally I would give this a C3, but in this case the manufacturer states RCD required, so am erring towards C2...

    Sub Board fed from a plug top, EICR Coding

    I recently undertook an EICR report for a small house and the conservatory extension had a separate fuseboard which was fed from a 13A plug top. Obviously this is not ideal but when coming to code it I couldn’t describe why it is any more than a C3. The main distribution board feeding the...

    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...

    Coding question - Twin and Earth Tails

    As above really. First time I have seen this but its basically 16mm twin and earth connected straight into the outgoing side of the meter, and into the consumer unit. Quality. Couldn't quite get a picture of the external MET but can confirm an additional cable has been added to bring the size of...

    Eicr coding query

    I am wondering what the installation methods should be for cables run under floor boards and then into stud walls but without thermal insulation...102,103 dont seem relevant and so my understanding leads me to think it would be a cross between c for clipped direct under the boards and then b for...

    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...

    Coding for a Ring Final Circuit 1.5/1mm

    Afternoon all, A quick EICR question. I have found a Ring Final Circuit that has been run in 1.5/1mm twin and earth. It is RCD protected and OCPD is a 16a type B MCB. All testing has come back as expected for a Ring final that has been installed in 1.5/1mm and the measured Zs is well within max...

    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...
