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.

    However there’s no specific regulations regarding the ordering of devices in a consumer unit, it’s just convention to put the largest protective device next to the main switch

    Depends on the training. As an apprentice for 5 years no less, in the Scottish steel industry.many moons ago; as a basic design feature, the ratings of equipment for connecting to busbars, was decided according to their Amp rating in order to minimise I²R losses, this was a basic design feature whether mickey mouse CU's or larger distribution equipment.
