Shower

[Cj24]

Hi, I have just been to look at a mates shower because he said shower kept cutting out and the pull cord was hot, I opened it up to find the live and neutral were melted together, I also looked at the fuse because it has now blown but it was a 30amp BS1361 Wylex fuse, surely this should be 40amp as it's a 9.5kw shower, does it matter if I put a 40amp fuse in bearing in mind the fuse carrier says 30amp on the side, this is obv just the casing but will obv be wrongly identied

Not worth this reply

The nail is better than a 40A though!

The other option is just to loosley wrap some 30A fuse wire several times around the pins.....Give it a good shuv and it fits!

I am fully aware of and rcd or separate shower unit, but I am just wanting to know that I am best telling them to put on a 40amp, I'm not actually doin the job for him, he can't afford it, but surely 40 is better then 30amp

Are you on a wind up?

If you are not doing the job, the BEST thing you can advise as a MATE is to get another electrician in if you cant do it!!!

Basically, if u put a 40a mcb on a 6mm cable then ya cable will melt before ya fuse

I advise u call a sparks in to do it for ya

Im new as you guys know so bare with me

Shower is 9.5kw so thats 9.5 / 230v = 41.30 amps

6mm t+e clipped direct will carry 47amps

So on the above a 45amp MCB would be needed but you would be quite on the limit and i would personally prefer a 10mm t+e cable.


but i doubt its clipped direct more like ref meth 102* maybe ? so that means 6mm t+e will be dropped down to 35amps.
Meaning the shower would be pulling 41amps but the cable being only able to cope with 35amps if it was ref meth 102* correct ?

 

[telectrix]

not really. think he's got the idea that 6mm cable is ok protected by a 40A , but has come for advice to confirm or reject his idea. clipped direct, the 6mm is fine on a 40A, but depending on installation method, this may be unsuitable. the only way to be sure is to know the ccc of the cable, depending on reference method, and calculate from that.

Why not put a 50 in? sureley its better than a 40?. rcd shower unit with 32a mcb will do the job.

 

[DurhamSparky]

just wire it straight to the mains...! 80A 33ka fuse will do the job.
