advise please re spur on a shower

[Plonker 3]

I know it's not ideal and the jb is certainly wrong but, if installed correctly would it be that bad? That spur could be running a extractor fan which could be connected to run when the shower switch is on.
i know the shower pull cord is a isolator and not a on off switch but that's another debate.

Please tell me you are joking?

No wasn't joking, now it's not something I've thought about doing and why would you need to as the feed for the fan could From the lighting circuit which would be in the same loft.
all I was saying is what really would be wrong with it? Spurring off a shower circuit for fan, fan would be fused down to 3a in fcu, cable to fcu same size as shower circuit.

And if you wanted the fan to run on you could use a perm live from lighting circuit.

now that bit I am joking!

 

[Billythekid]

haha, you left your green and yellow sleaving in the loft as well

No, I'm a consummate professional. I left that there for the next "leccy" to use-you must know how annoying it is to forget the sleeving? ;-)

I would seriously read up on the regs, as my signature says i will note quote them, god damn i dont know them all ! but spurring off a shower supply has to be wrong in so many ways

Stop being silly, if this is after the isolator you won't have a neutral. You'll need perm live and neutral from light.

Good point, you could take the neutral from feed side of the isolator. Lol

Well IIHO
You could "upgrade" the cable by putting it on top of the rockwool instead of underneath.

thanks for all of the comments guys. ive told the client about it
she asked my opinion so i am going to put in a new but of cable to the shower and run the spur off of the ring

so thanks again :8:

 

[shocking_eg]

at the end of the day inst it a radial circuit ???

yes a big one at that, but it is.

so i don't see whats wrong coming off with a spur as long JB is suitable and rated correctly and the cable being spurred off is the same size as primary cable or rated correctly in conjunction with the over current device ?

I may be wrong here, so please feel free to correct me..

Well there is such a thing as good practice I suppose, some sparks would and some wouldn't :winkiss:

bad practise. the shower supply should only feed the shower and the extractor could be picked up from the local lighting circuit via a fused spur and fan isolator.
My advice to you would be to flag it up (bad connections, cable not supported, junction box not secured/maintenance free junction box not used, cable big enough to carry load?) on the test and inspect cert as you've noticed it as a defect whilst doing other electrical works within the house.
