Range Cooker Connection Refusal.

Zoomup

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.

 

Z.

    is it ok to to wire a hob to a 100A switchfuse using 25mm tails, as long as the lugs fit?

    IF you allow a scaling up of the way most electronics is designed, then so long as the casing of the cooker can contain the explosion products, you could argue that the answer should be yes.

    It is  certainly the argument used for the 1 time PCB track 'fuses'. Either the internal wiring will blow to clear or the external fuse will pop, both are safe outcomes.

    Not sure I'd actually want to do that with 100A for anyone but myself, and it would have to be a bad day.
