10.8kw shower

[spraffers]

hi guys, im fitting a 10.8kw mira sport max, i have read various threads on this and i think 10mm cable is suffice but the problem is at the moment my cable runs into the old cooker fuse on an old fusebox which is 30a.

I know i need an rcd fitted, it is wire through an isolator switch.
Can you please advise what i need to fit? eg rcd etc

25mm cable direct to cut-out fuse.:27: that'll solve the volt drop. why such a ridiculous size shower? a 7 kW gets you just as wet.

47A to deal with hope its not an old board

Can you please advise what i need to fit?

A fire extinguisher.

Seeing as your profile says you are a carpet fitter, i suggest phoning an electrician would be a good start.

Hope that's not water

You will need the shower installation certificated anyway, so call in an Electrician to start with, not the fire service after you put 47 amps on a 30 amp circuit.
What do think of carpets fixed with panel pins or thumb tacks, dumb, so take advice with electric regulations, on the way that it must be done !

A fire extinguisher.

Tony,why is it always worse case scenario? He may not need a fire extinguisher at all...just a defibrillator...:stooge_curly:

I have got a Mira sport max 10.8kw.

Yes it does get you wet like a 7kw, i can turn my one of full whack and my hot water comes out fast not a trickle like a 7kw.

Its a very good shower, I've got it on a 50A with 10mm cable.

cheers to the guys who gave helpful replies

So are you going to put your family and home at risk?

 

[uksparks]

Hopefully he won't.

You never know with a part P qualified carpet fitter.

use 10 mm cable providing the run is within the regs a 10.5 shower draws a lot of current-- the board needs to be able to handle it a 45 amp breaker or fuse would do the job
btw ignore the childish posts

Well i have a 4.2or 4.7KW (can never remember which) shower over here in my flat and the water volume/pressure is more than adequate as is the the water temperature. Never had one in any of my own houses, never had the need. 10.8 KW just sounds totally ridiculous to me, just in running costs alone, especially if you have teenage daughters. ...lol!!

 

[ayjay]

can anyone remember the early electric showers?
the element was visual in a see through plastic enclosure 6kw maybye
i installed one for a freind ( a scouser) his son used to spend far too mutch time in there doing what young lads tend to do

He's a carpet fitter.
If you fitted your own carpet with half a clue of what your doing and no underpinning knowledge do you expect an excellent result?
Now turn the tables. Its an accident waiting to happen. How can he test his install to make sure its fit for use apart from getting a spark in? He may aswel get him/her in to do the lot.

I don't mind it when advise is given but it looks like a free training Q+A! Would you ask a brain surgeon questions in the hope of removing a brain tumor?

(Unless he is training to become an electrician and just working as a fitter to put bread on the table)

what's a brain?
