Hey what kilowatt showers can be feed off 6mm cable and which need 10mm? I guess the distance from the fuse board also needs taking in to account?

We are putting in new shower supplies in at Clapham.
5.8kW = 37A
40A OCPD required
single cable in surface trunking has a max of 41A for 6mm cable.
6mm cable it is then...
ah but it wouldnt be a 5.8 would it.well at least get ohm's law right. 5800/230 = 25.22 A according to my arithmetic.

i have only come across 6,8.5 or 10kw electric shows
the manufacturer's like round nunbers
well at least get ohm's law right. 5800/230 = 25.22 A according to my arithmetic.
if its 250 then it would be less.Yer right Tel.
But why 230v ?? is this by enquiry, assumption, or a true measured rms voltage.
Thinking outside the box (not recommended for DIY man, go away)
but food for thought never the less.
Be gentle with me no more abuse pleeeeese, lol.

its rare to see 220v and even then it would only increase a little
Well if Baldsparkies wasn't bald, he will be now! Crikey, a vague question got a vague answer, like most questions and answers on the forums! All this bickering over such trivia lol. Come on chaps
Its even more rare to see 230v shanks, and often that's the baseline that's used for obvious reasons.
And yet when I dared to suggest 6mm as a possible cable size for 8.5kw I was summary abused ??
Despite that, it will be used. And if Mr DIY is going to use it it's wrong.
But on an electricians forum, and with all other factors taken into account, can can and does prove satisfactory in the real world.
So there you have it, some people are getting trashed for saying 6mm, some people quite happy to use 6mm.
Hope others are paying attention here, cus amongst qualified electricians there are indeed differences of opinion, and you know what dependant on the situation both are entirely correct.
And that's the whole point, and no abuse needed.
I started off bald so I have nothing to lose.
But nine pages in, what the hell do you think the DIY electrics, plumber feels like who asked the damn question in the first place. lol.
i think you have a typo mate.
you put 5.8kw i think you mean 8.5
Genuine mistake and he gets abused ie accused of being a dxck lol
I have to laugh because you couldn't make it up :6:
Shocking that it is allowed to happen. I just got banned for starting a harmless thread in which I even said I was only joking. It will be interesting to see what is dished out after reading some of these replies.
beat me to it. using 230V will give a worse ( higher) value for current than using the actual ( 235 -240V ) so errs on the side of caution.
Wrong.
7kW @230=7.55Ω=30.43A
220V=29.11A 6.4kW
240V=31.75A 7.62kW
250V=33.08A 8.2
The resistance is regarded as constant.
so, power output varies with the voltage.
Hi-Geordie, hows you doing bud?Morning Tony ... You're up early.
Ohms law= current in proportion to potential difference (voltage) if temperature is constant.
Hi-Geordie, hows you doing bud?
Why, finally it's going somewhere.
