Chasing Cables for Shower Advice

[SarahCollen]

Hi, we are having a shower fitted - the electrician has run the cable vertically over the top of the noggins, meaning when we make the wall good the filler will encompass the 10mm cable he has pinned to them. I'm certain this is not correct, so I'm tempted to retrospectively cut the cabling into the noggins - approximately 6 of them, protect them and then plasterboard and skim over the top. Any advice? Obviously the cable is not yet connected to either the shower or the consumer unit. He's also used plastic clips and I don't think these are allowable now. Thanks Sarah (18th Edition Domestic Installer)

Just asking....have you seen his details and checked him out?

It's my partner who has employed him, based on a recommendation from a friend, I would have attempted it myself but Domestic Installer doesn't cover me for bathrooms. I'm pretty sure I'd have done a better job though. Once I've installed the shower, he's coming back to connect it all, I'll be there so I'm going to ask for his details. (I'm NVQ 2, City and Guilds qualified too)

Hi Sarah,not quite sure what an 18th edition domestic installer means , but first question is why you have not done the job yourself ?,the install looks (and difficult to tell from piccys) that it has been done with minimal disruption, lets say the noggins were 50 mm deep then it makes no difference if the nogs were drilled in centre or on surface ,the cable would still be less than 50 mm deep, as for plastic clips well it doesn't look like it would trap firefighters round there necks ,but cant be sure, not sure where this is going to be honest ?

It's in a bathroom and a new install, neither of which I am qualified to do as a Domestic Installer. The noggins are neither drilled on the surface or the centre and once filled some of them will protrude through the plaster. I understand the plastic clips bit now, I mis read the regulation but thanks for re in-forcing my knowledge on this. I was just trying to find out if what he had done was legitimate as per the regs as personally I think its a rubbish job by an amateur and I want it to be correct.

Hi Sarah thanks for your reply ,i just don't understand if you are a domestic installer why you can't do bathrooms and or new builds / it makes no sense ,or is it me ?

What sort of Domestic Installer can't work in a bathroom or new builds.....you've lost me know are you registered Domestic Installer or not?

 

[multimick]

my point exactly.

 

[Markyd]

Yeh......I'm done

I am a qualified Domestic Installer with Part P Qualification, I could do all the work but some of it would need signing off by a fully qualified electrician. I'm not doing any of this myself, I just wanted clarity on the cabling which you've now all helped with. I'm a plumber and I took the Part P to cover the basics in electrical work if I needed it. The shower is a new install not an upgrade. I'm off to bed. thanks again ?

Please read the regulations carefully before jumping to conclusions

People with bit of knowledge, you employed him on recommendation, first you have to understand how a building is constructed to then understand what he has done to install the cable the way he did, how would you have installed the cable.

Sorry Phil I don't understand what your saying. And neither am I going to say how I'd install it. I charge for that sort of advice/work, not give it away free on the internet.

Nice neat rectangle holes cut out over the studs, 20mm holes through the studs, feed cable through, replace rectangle cut outs and fill. Too late for that now though!

In an ideal world, cable through holes drilled in the noggins half way through the wall.... but it’s not ideal is it.

Multi tool or drill to check slots into the wood, so cable lies behind the plasterboard.

If it was a brick wall, cable would be just under the plaster, not 50mm in, and would be rcd protected.... which this circuit will be, being a new circuit in a bathroom.
