Range Cooker Connection Refusal.

A lady today asked me to estimate to do some cooker circuit alterations in her house. She has an old electric range cooker in the kitchen which she is to replace with a new one rated at about 11.2kW.

 

A certain national electrical retailer would not connect up her new and paid for range cooker as the cooker supply is run in 10.00mm2 T&E and protected by a B50 M.C.B. plus R.C.D.

 

The reason given was that the supply is too big and will overload the new cooker.

 

The retailer insisted that the  B50 M.C.B. be replaced by a B40 M.C.B. and the final cooker connection from connection unit to cooker, be run in 6.0mm2, the 10.002 final connection being removed.

 

Comments please.

    I will add one extra point. It is often difficult to add another circuit to many modern properties because of the construction, typically concrete floors both up and down. Mostly it should not be necessary, and it is simply needlessly expensive.

    gkenyon:

    So the house was not built to take into account reasonable changes that might occur in its life? We know how poor some new builds are. Is that the appliance manufacturer's problem? If it's a must to use  such building materials, cables can be run in suitable containment or ducting. It's not that hard to design in to be honest … who's skimping now?

    Give me floorboards any day, but please not T&G.

    Cable drops without capping are pretty final. I don't think that my self-build chum would have wanted to go to the bother of building in service voids in the ceiling cavities, or even installing some form of conduit or trunking. Clipped to the (web) joists was much easier - but not that easy.

    Ideally, the downstairs socket rings would have been tested before he closed the ceilings, but he did the first fix and I said that he shouldn't be worried if he has confidence in his own work. 

    I think that various mistakes have been rectified. For example, the absence of a conductor joining the various thermostats.

    The one and only bit of forward planning has been the cooker circuit. After detailed discussion, he chose 6 sqmm. That's for a gas cooker, which if it is like ours, won't even need leccy. Maybe hers will have a clock or electric ignition?
