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.

    If you had a CU with two RCDs and four MCBs for upstairs ring main (32A), downstairs ring main (32A), kitchen ring main (32A), and outside socket (16A) then how would you connect them up, and why? If you then had to add circuits for a cooker (32A) and a central heating boiler (16A) which RCDs would you connect them to, and why?
