advise please re spur on a shower

[mc-elec]

hi i was doing a job today and noticed that a plumber had done some work and he had spured off from the supply cable to the shower from the switch. In my apprentice days i was told that this should not be done and if i remember correctly it says in the regs
any advise to what to tell the client would be great

as the plumber is her ex husband

in my thinking the shower should be rewired and the spur taken from the ring

please see attchments for pics

thanks

What's the spur running? A fan? What's the rating of that jb?

 

[ashrow]

i would not spur off a shower circuit
(To even get 3 X 4mm T&E in a JB must of been a neat trick)

 

[MDJ]

Hmm, tidy Job there I see LMAO, great professional connection of the JB, it looks like a 20 amp lighting JB will, nice bit of excess cable to the spur as well haha, must be a skilled mans work.

 

[telectrix]

what a plonker!

 

[electric will]

Though it looked like a 20a wonder if some of the strands on the cable have been cut off to get them u der the screw terminals and I bet it's not a screw fix jb!

 

[SYKRAPS]

If the cabling is of the correct size there will be no need to re-wire the shower just remove the spur and improve the jointing method.

You just need to source a new way of feeding the FCU.

Plumbers doing electrical work makes me mad when they know the dangers, you would never catch me playing with gas.

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.

I see your point, we need to know what the FCU is controlling

 

[electric will]

Might be a cooker lol

 

[SYKRAPS]

Might be a cooker lol

LOL yes or maybe the shower is spurred from the 1.5 t+e going into the FCU

thinking outside the box, I like it!
feeding a cooker and a shower spurred from the upstairs lighting circuit.

 

[telectrix]

plumber, plunger, wethead, plonker. all got 7 letters. coincidence ???????

 

[Billythekid]

Damn,

Knew this would rear its head one day!
I thought it was a work of. . .:4:.

Atleast I'm no cowboy, and moved some insulation :rofl:

 

[MDJ]

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

Please tell me you are joking?

 

[electric will]

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.

 

[electric will]

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? ;-)

 

[ashrow]

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

 

[Billythekid]

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

now that bit I am joking!

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

 

[lauriehurman]

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..

 

[MDJ]

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

 

[Novo]

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.
