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.

    I have installed economy seven consumer units with alternate ways left empty to allow the MCBs to run cooler.

    A holier than thou and a cavalier attitude. Being economy 7, there would be long periods of no activity on MCB's. 1. How would the overall I²t losses, be affected with that arrangement?. 2. Would the maker concur with that arrangement as being necessary?. 3. Would the customer be paying for your design. 4. Would you advocate that arrangement for all C.U.'s. 5. Would you advocate others to follow suit. and the bottom line for dollars and sense - 6. Would it make you competitive? ?

    Read some manufacturers instructions for installing MCBs which will be fully loaded for up to seven hours.

    Does this imply derating?, for my edification and others, please give a link to these manufacturer's instructions.
