Workers accidentally cut the wire... I'm looking for advice.

[alexkiran]

Workers accidentally cut the wire with some power tool. It's a 2.5mm ring circuit wire with 20A breaker.

What is the optimal way to fix this?

Thanks in advance!

There is no enough slack, unfortunately. What kind of maintenance-free joints do electricians use in the UK?

Wago along with a Wago enclosure, in the floor space.

Regulations differ in the UK to the Republic of Ireland so alternative measures may be required. @Risteard will advise better if he sees this.

 

[Pete999]

Beware of people saying it's only a temporary repair, insist on a proper repair, seen many a temporary repair left in as permanent, and also insist on a MNEW certificate for altering an existing circuit.

I don't believe Minor Works Certificates are applicable in the Republic of Ireland.

if space is an issue,in line crimps or proprietry connectors like "ideal" with heat shrink ove each joint, then heat shrink over all 3. or 1 of these beautys, also with heat shrink over to reinstate the sheathing.

In Line Spring Lever Connectors

Use these 32A spring lever connectors for an easy, fast-fit connection. The levers are a real time-saver, and the compact design makes them easier to work with in confined spaces.• 3 in 3 out inline lever connectors• Spring levers for easy, fast-fit connections• Colour-coded for live, neutral...

Well whatever cert does apply in NI then Westward 10 if any.

So you inferred in you previous. can you suggest an alternative method or are you just being obtrusive?

The first thing I would note is that there is red and black insulation on the conductors. Either this installation is quite old indeed (red & black went out in about the '80s off the top of my head) or was wired in incorrect colours.

As for minor works these do not have to be certified, but if a Registered Electrical Contractor (REC) carries out the work then the customer has a right to request that a Cert No. 3 is issued with the "minor works" box ticked. Cert No. 3 is the certificate for works which do not require DSO involvement. (Prior to the introduction of Cert No. 3 there was a "Declaration of Compliance with ET101 for Minor Electrical Installation Works".)

But as the OP has stated that he will involve a REC to repair this then the REC should be able to advise on the best course of action. Certainly with the obvious damage I would be expecting that length of cable to be replaced - ideally back to the outlet it comes from.

One thing that has me confused is with the age of the installation (taking account of the wiring colours) why the socket-outlet is at that height. New work must be within the range of 400mm to 1200mm - perhaps it is lower there and I've just misjudged from the picture. If the socket-outlet is rewired it will have to be set at this height.

Pete I am suggesting few members on here are fully conversant with the requirements in the Republic of Ireland. Maybe suggestions for rectifying this issue are acceptable, maybe not. Those best placed to advise are members from that country so correct advice is given. Being obtrusive??

 

[Dustydazzler]

you were lucky , most builders would have simply wrapped a bit of rough old gaffa tape round that cable and plastered straight over the top of it...

The house was built in the 80s, so it might be an old original cable there. I've measured the 400mm is to the top of the socket-outlet. Is that OK?

I don't think the socket is new work. The existing wiring got damaged during other works.

Indeed, sorry for the confusion. I wasn't suggesting that it was new work but that the electrical installation might be substantially old. As such there may be many other issues which should be dealt with (e.g. undersized tails; inadequate Earthing, bonding and neutralising; unearthed switches etc.; possibly no RCD on socket circuits and perhaps old Diazed fuses).

It's not an issue for the old wiring, but the 400mm is to the bottom (not the top).

My point is that if it is rewired then it will have to be raised to the new height.

You are right... the replacement of the fuse board is planned. This is how it looks now, old fuse, but I have RCD at least. I'm not sure how to handle the other possible issues you have mentioned.

Got it. Thanks!

Got it. Thanks!

My god, that looks like a downlight sticking out of it! ?

I have a feeling that is an emergency light
