Obvious departures from the regulations at first glance at a new consumer unit.

Jaymack
I was asked to give an EICR on an domestic property which is to be placed on the market (part P applicable). I found that a builder as part of the other renovation work, (new doors, windows and kitchen etc.) has carried out the installation of a new metal consumer unit. On first opening this dual RCD unit, the 2 lighting circuits were on one R.C.D., and the 2 final ring circuits on the other R.C.D,, it was obvious also, that some wires to the new CB's were short and not lengthened, resulting in a bird's nest at the M.C.B.''s.


Plainly, a qualified electrician hadn't carried out the work. What would the readers as registered electricians have done ?. 1. Walk away. 2. Propose to have an E.I.C.R. carried out (UNSATISFACTORY), then carry out the rectification work and issue MWC's.3. Rectify the obvious departures, issue M.W.C.'s and then issue a SATISFACTORY E.I.C.R.

    So if a shower or appliance  circuit is added to a domestic consumer unit should the whole CU be stripped to move the protective devices along to position the new protective device next yo the main switch or can it go after the existing lighting circuits.


    I think we all generally line the CPDs up in descending order starting at the main switch, but in reality I’m sure that’s custom and practice rather than out of necessity.


    I did the electrical work in a kitchen for a High Court judge some years ago and his wife passed comment that he had spotted that I had all the accessory screws stood to an attention, I know how to be an anorak and apparently he likes anorak wearers to work in his home. but I know that some installation details don’t really make a difference. Actually the screws could be slightly over tightened or slightly loose to get them all lining up, if you used a torque screwdriver they would not line up.


    In a domestic installation what are the chances of a MCB or RCD protecting a lighting circuit with all LED lights ever tripping without some external influence? The days of a light bulb or lamp blowing and taking out a fuse or MCB are numbered.
