What size cable do i use for an electric shower?
Question:
Answers:
Hi my husband has just told me that it is 10mm.
It used to be 6mm but if you go to a good shop anyway they will advise you .
Our shower runs with a 10mm cable.
4mm^2 at least.
4 square millimetres per conductor will provide at least 32A.
Mind you, I'm on 3 phase. Installed by professional electricians some years ago
mY electrician always uses six mill,The showers paper work should have the info you need
If you don't know the answer yourself, are you qualified to do this? In electrial work ignorance = death. Please be carefull buddy.
As a rough guide: If it less than 8.5 kw use 6.0mm2. If 8.5 kw or over you will need 10.0mm2.
Any cable that is rated to 13 Amps
In the UK all electrical work in the bathroom must now be carried out by a qualified electrician under Part P regulations. If it causes a fire and you DIY'd it you'll have no insurance, and if you sell your house it could cause problems.
YOU NEED 10MM OR CABLE THAT TAKES 30AMP
as a spark to trade ...the 16th wiring regs state it has to be wired in 10mm.......4mm yeah right ,,you better have the fire brigade on speed dial..oh and use a 45 amp circuit breaker.....so if its a 10kw shower it works out about 4 amp per 1000w
I would use 10.0mm cable. You can use 6.0mm for a small shower but you may later want to change it to a bigger one. Also depends on the length of cable required.
****LISTEN UP****
I rent the house I live in at the moment, about a year after we'd moved-in, an electrical safety test thing was done & was reported that our shower was fitted with 6mm wiring, which needed to be changed BY LAW to 10mm. It now has 10mm wiring as an electrician was sent promptly to change it.
10MM!!
(But as a chap stated before, If you don't already know should you be doing it? I'd wire a plug, but not a shower!! No way!)
I can only agree with 'BFD' if you dont know that then you dont know enough to put you life at risk. Dont do it.
showers which are rated between 7.5kw and 8.5kw require 6mm minimum.showers above this require 10mm. these figures are only a guide and are dependent on various other factors (length of cable run etc). even if your shower is at the lower end, I would install 10mm cable in case you want to upgrade. having said that, some of the other answerer's are correct, you now either have to be a qualified electrician or have a certificate of electrical competence( domestic) from a college. I am an electrician and the fact that you even have to ask this question has set alarm bells ringing.PLEASE DO NOT ATTEMPT THIS YOURSELF. CALL IN A SPARK.
If you are doing-it-yourself then you need to submit a building control notice (in England). Despite other (mistaken) posts, you may still work on your own electrics, but there are additional restrictions and requirements.
The instructions that come with the shower tell you. you need stronger cable for stronger showers basically.My shower cble is 7.5 if I want another shower I have to get same.
it must be 10mm and wired direct to a 30 amp trip fuse (circuit breaker), and must be done by a qualified electrician. IT'S THE LAW.
if you live in the UK ..then you are not allowed to wire a shower yourself ..this must be done by an nic regd electrician ..this cable must run through it own mcb ..and only a qualified sparks can do this ..then he should give you a certificate to say it has been done correctly ..this work should be inspected by building control..this is the law
Go for the 10 mm installation in your raining room,treat yourself with a gentle to a massage from a power shower,i did and never will regret it.
Always ensure you have a 30/45 amp R`C`D switch installed between meter and raining room for safety reasons,i need not mention.
depends on the length of run from the fuse board to the shower and also the kw size of the shower, if in doubt i`d use 10mm
between 10 and 15 mm
depending on how many kilo watt the shower is but you should use at 16mm twin and earth
To save any issues and to allow for future upgrades, allow a cable size of 10mm, and a pull cord/isolator switch capable of taking 50 amps, and a mains circuit breaker to suit the load, and get an electrician to do it if you have any doubts whatsoever.
