I do occasional work for a kitchen Company.
Was asked for a supply to a 20A Oven.I put in a 2.5mm T+E radial. No insulation/reference method C, so the cable is good for 20A.

I went to do the final connection today, and had a quick look at the Instructions.
Makers plate gives a 5000W rating, which is a little above the 20 I was quoted, but with diversity will still be good.
First - "this appliance should be installed by an 'NIC' Contractor" Presumably NICEIC. thats me stuffed then, as I'm with NAPIT.

Then, this appliance needs to be supplied by 6mm T+E, and protected by a 32Amp circuit breaker.
Then, the final connection should be via a 6mm CSA 3 core flex.
No requirement for heat resistance, no cable spec etc.

Clearly this oven will run fine on a 20A CB and 2.5mm T+E, and 2.5mm 3 core flex.
However, if I follow the instructions, I wont be able to install it anyway, and it will need a new cable and CB installing, which is out of the question now as the plastering is finished.

What is done in situations like this?

Thanks
Alan.

looks like they might be changing that reg in amendment 3, so if you can just put the job off for a few months.

134.1.1

You know the one, " must be installed in accordance with manufactures instruction."

maybe change to , " shall take account of manufactures instruction."

I think that adds some more room for argument.

just so we can have some more ambiguity.

Isn't that just reinforcing the emphasis on 'design' rather than directive. That was the intention of the 15th onwards - allowing flexibility and not being prescriptive.
Mind you, it does mean you take responsibility for your work (like it says on the certificates) and that means (as I've often said) how can a third party inspect without the original design assumptions.

Gosh it's late. I'd better go back to bed.

Even some modern led track light fittings from tlc within the last month said I should connect them to red and black cables. That's me on the naughty stool then!
