Joiner drilled through cable

[SUNRAY]

The cable is clearly damaged and should be either repaired or replaced. Whilst it may not reveal itself during testing, this does not mean that it's not potentially dangerous.

Also, the NICEIC contractor is prohibited from issuing certification for jobs which he did not supervise during the erection of the installation. He is not permitted to issue a certificate for someone else's job, so the certificate you have received is invalid, null and void. He should have been reported to the NICEIC for breach of the Rules of Enrolment (or rules of registration if he is one of these so-called "Domestic Installers" as opposed to the proper scheme, which is the Approved Contractor scheme).

I would only expect a cert to cover new works, even if the new work extends an existing circuit. I assumed in this case the damaged cable was existing and outside the remit of the new certificate.

I have an approved contractor NICEIC certificate.

An electrician cannot sub-contract jobs? He has to be there himself 100% of the time to be allowed to issue the certificate?

A company cannot have more than one electrician completing a job?

No the cable was part of the new works. It got damaged after installation but before testing for the certificate.

Oh Blimey no, That he should not have left.

Brand new should be perfect.

I've bitten the bullet and removed the wall unit, attached are two pics:

Not good is it?

I would like to next test for continuity. I have a multi meter and have asked in previous posts about how to do this. My plan is to remove a socket cover and test this way rather than at the consumer unit. But do I need to turn all the power off to the house or just the circuit in question.

Thanks,

Bob

So how to repair this?

I done some research and come up with.

1) Replace the damaged cable completely, so will need to find the other end of the cable. Thing is directly above are a sink and shower so access from above is impossible. Also above the ceiling are water and CH pipes, very reluctant to start cutting the ceiling plasterboard with a knife. Also thinking about it this may be the first socket from the CU.

2) Get an electrician to crimp and sleeve it, but after reading about this on DIYnot, doesn't this become a weak spot that could fail in the future?

3) Use a junction box placed above the wall unit and on the OUTSIDE of the plasterboard, then I just need to replace the cable down into the socket. A junction box like this should be classed as accessible should it not? Ugly maybe, but surely safe?

Or something else?

Thanks

Bob

As it's plasterboard over blocks:

Single 25mm depth metal box recessed in the wall above the cupboard
Pull old cable up and into that box - cut away damaged piece
Pull new cable from that box to the socket below
Join cables in the box using connectors
Fit blank plate over the box.

Should not be visible from ground level once the cupboard is refitted.

The contractor enrolled with the NICEIC cannot certify works carried out by another company. They are entitled (and indeed obliged) to certify the works which they (their company) have carried out. The exception to this would be on large jobs where they only sign for Inspection and Testing of the installation, however this requires them to inspect (and test) the works during erection and not simply on completion. For domestic jobs to certify for Building Control purposes this isn't even permitted - they can only self-certify their own works.

As such the Electrical Installation Certificate is invalid, null and void and the Approved Contractor has acted wholly in contravention of the Rules of Enrolment for the National Inspection Council for Electrical Installation Contracting.

Great, many thanks

I would use a flex outlet plate rather than connectors and blank plate, the connections are more robust

Are they rated correctly though?
