40a circuit breaker6mm t+e

[Stevec1999]

I have had my kitchen rewired and plastered. I have had a 6mm t+e on a dedicated 32a circuit for a 60cm electric cooker. In hindsight, had i known at the time, i would have asked for a10mm cable to future proof the installation. The cables run from the consumer unit in the attached garage, into the single storey flat roof joists, to the wall of the kitchen. The cables in the garage are in trunking (to keep them tidy). I have been told that if 6mm t+e is installed using method C it is good for a 40a fuse. As things stand, because of the trunking, the installation method is method B. My question is, if just the cooker cable was taken out of the trunking, then clipped to the brickwork, and carries on into the kichen roof, would this then constitute method C. A larger 90cm cooker could then be installed if so desired in the future.

How long is the trunking and how many other cables are in it?

3.4m of trunking with15 other cables in it.

OK. There are some will argue that's not brilliant, and there are some (like me) who will argue that in practice that's fine. So if there's an easy way to do as you say and clip it directly to the block instead then that would be better.

i don't understand what you are saying.

I'm saying that the easiest way to solve your conundrum without having to go into a whole heap of intracacies and maths is to do as you suggested and take it out of the trunking and clip direct (method C).

Thanks for the help.

What is the power rating of the larger cooker? Does it actually need a 40A supply?

Almost certainly won't! We've been here before..... many times......

It's a Rangemaster 90cm, 14.8 kw. Rangemaster say a 40 amp breaker, but the diversity calc says 32a is ok. It's more about the warranty with Rangemaster.

Being on a 32A MCB shouldn't affect the warranty.
Being on a smaller MCB than recommended can't cause a fault to occur in the cooker.

Thanks for your time and opinion.
