11kw shower cable size?

[Outspoken]

Tel, that is how I would interpret the regulations because that is a clear delineation between one conductor and another.

Now I would like you to please explain to this gaggle of highly qualified, experienced and knowledgeable Electricians and Engineers why you now believe you are still correct, and if your going to quote Regs, please do not snip them, but quote the whole sections and then attempt to argue your case.

I'm in the gaggle seats but not in that list

Being as no-one here asked the question on the IET site, I've done it for you, maybe worth a read, and see who is right?IET Forums - 433.3.1 (ii) - open to interpretation?

11kW @ 230V = 47.8A
11kW @ 240V = 45.8A

Whichever way you look at it 6mm² will not be sufficient because the CPD will need to be a 50A MCB as Tel has already stated.

You need to state how the cable is run however, because the environment the cable is installed in dictates how much it is de-rated by, and you could end up with 16mm² if your running it in fully insulated spaces or in an environment subjected to external heating.

i need to know if i used 11kw 3phase motor 380v, what size of cable can i use?
