Bathroom electrics.

[Mr Bump]

Hi All, glad I found this place, ... loads of info

I'm in the process of ripping out and then refitting a bathroom, I have an electric shower fitted which I am discarding. What I would like to know is; can I re-route the exsisting electric source for the shower and use it for an electric light?

Cheers

You could, but i wouldnt....

How you going to get 10mm cable into a light fitting block?


Dont forget your in a bathroom, so all this work needs to be notified etc...


What else you doing in there....

FYI Ive just done ours, and I esitmated 1 month, it took me 4....lol

... I thought there might be some sort of adapter available.

You ask, "What else you doing in there.... " Basically, ... everything, and if I finish mine in 4 months I'll be well pleased

Are you suggesting that there is not going to be a lighting circuit nearby?

Think about it this way, If you have a hosepipe that fat, and you couple it up to a thin one, where the joint is, there is lots of preasure.... and that where your more likely to get a leak / pipe burst....

Electrics is best thaught the same.... 10mm cable jointed or adaptered to a 1.5mm lighting curcuit you have an issue where you could cause a hot area in your cabling.... Heat could lead to Fire..... DONT do it.... not worth it....

Id tap into your existing light cucuit if you wanted to add more lights....again notifiable....lol


Took me 4 months to fix all the bodged jobes the prev owner had done.... im sure ull find some of my posts on here somewhere about the shoddy work i found....


P.S. Good luck with it....

... yes, there is an exsisting circuit, I just though I may be able to use the shower electric cable for a planned mirror light.

Thanks for the comments. I'll most probably get someone in if it's notifiable.

Cheers

BS, joints any joint in a pipe is a potential point of failure but the pressure at your joint won't be any higher than that further back up the thick hoze.

again this is bullshit, connecting two different sizes of cable together isn't going to cause a hot area or anything like that.

however the breaker for your shower cuircuit is too high to aqueately protect. You could change the breaker down or use a FCU to protect the lighting wiring but honestly i wouldn't do it without a very good reason, much better to have all ceiling lighting on the lighting cuircuit if possible.

also note that this work being in a bathroom is notifiable whatever source you choose to use for the supply.

If the breaker is the right size for the weaker cable it will be protected BUT you shouldn't change cable size on a circuit without a fusedown such as an fcu. You can wire for example a 6mm cable into an fcu and then continue in smaller cable as long as it is protected by the correct fuse. Obviously you can't have this inside the bathroom though unless it is in a safe zone. But definitely the best bet is to use a lighting circuit and disconnect the shower cable from the fuseboard. Using a heavy cable for a lighting circuit could cause confusion and is not good practice.
