New pre flexed 2.5mm Cookers 2020

Kevin McCann · 23 Nov 2020

Was asked to change a cooker over for customer. Must be cheap from China with a hardwired 2.5mm flex prewired into the unit. The original cooker required a 10.0mm T+E. The question is.... Can I take of the outlet fed from the isolator with a 10.0mm T+E and put on a single socket or else a 13a Fuse Spur, protecting the oven 2.5mm flex from overcurrent? Thanks

What is the power rating of the cooker?

What do the instructions for the cooker say?

Need to double check the power rating but i'm just asking for the best method to protect the 2.5mm flex.

What rating is the fuse/MCB?

Kevin McCann · 23 Nov 2020

45amp

Still need the power rating of the cooker in kW or W, for a sensible answer.

Fitting a 13amp FCU may be not big enough.

Changing the fuse or MCB at the consumer unit may be the answer, if it needs it.

It can hardly be big wattage with a 2.5mm flex coming from it can it?

On occasion I have had to change the cables to Chinese bought items as have found the cable was all rubber and a single strand of copper (and a 13A fuse).
So cannot assume anything. Best to know the power rating of the cooker in kW or W

Hang on a minute, you're doing this for a customer?

A 2.5mm2 flex suggests the cooker will be greater than 13 amp.

I know what BAS would have said - and in this case I think he would have been right.

My guessing as since the cooker is a resistive load, the cable wouldn't over current anyway. A plug really should have been fitted already if it was required, so a socket isn't the answer. Personally, I would just wire it into the existing point.

Make and model would help loads.

2.5mm² flex could be rated to as much as 25 amps, or about 5.7kW. Far more than any 13A outlet could provide.
If this is really an electric cooker - a single appliance with hob and oven(s) in the same unit - then it won't be connecting to a 13A outlet.
Unless of course the hob part is gas and the ovens are electric, when it might do.

Either way, without details of the appliance rating, there can be no answer to the question.
