pls help-can some one please tell minimum requirements for burying cable in wall-than

mumofjusttwo

my builder has only buried the cables then plastered over the top of it. I need to phone him tonight I think and tell him to not come back only problem is I owe him £250 but don't feel he has earnt it.

One other thing anyone can install electrics subject to inspection by building control, but this means unless a large installation it will be cheaper to get an electrician do it anyway!

mumofjusttwo

do i need to get my electrics checked then?

Cknocker

At the moment the chances are the installation is illegal, as it is unlikely it complies with part P and that should be justification for with holding payment, unless the builder van give you a legitimate completion certificate with al;l test results which I doubt he can.

mumofjusttwo

is this the case for electricity down in a home?

As Zax says, it is perfectly possible the builder is capable of self-certifying. Seems sensible to find out before assuming the worse.

I have asked him and he says that he doesn't need it and could still do my home!

He has buried the cable in the wall and plastered over it. NO protection at all. Surely if he had been qualified he wouldn't have done this. I guess I have a cowboy!!

Cknocker

As I said, ask him for the cerificate before paying him, but from what has been said it is unlikely the system complies, although I don't think the wiring regs state the cables must be in duct, but it is certainly best practice. - ask for the certificate.

Cknocker

what work has he done?

Safest way is to chase the wall out deeper than the cable, buy some plastic shielding or oval tubing(can't remember what is't called..duh!) and plaster over. If you want to have the option to rewire at any time use plastic conduit. Means a deeper chase though.

And also best way is horizontal or vertical runs NOT diagionally

The new(ish) wiring regs are now in place (17th Edition / BS7671:2008). They state that cables can be ran lots of different ways (even diagonally now). The main proviso being there MUST be RCD protection (domestic cables supplying 13A sockets and other things I will nto go into)


So to answer

• No required depth
• No requirement to run cables up and down (better practise though)
• MUST BE RCD protected

If you have doubts about the builder ask (and get) BS7671 paperwork (Part P BS7671 paperwork in England / Wales).
Find out who the electican / electrical company is and look HERE to see if they are registered (I am assumning you are not in Scotland- if you are link is below)
I would suggest not paying in full until you see a copy of the paperwork (they can withold originals as you will need originals to sign off work, but they should give you a copy as this is a requirement)

You should use a competent person for the work, links below
