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

[Risteard]

I'm not sure how to handle the other possible issues you have mentioned.

The REC should advise when replacing the distribution board, as we are required by RECI and the CRU to ensure that the tails are adequate (16mm^2 is the minimum permitted by the ESB - if you have old 6mm^2 tails for example then they will have to be replaced), that the main equipotential bonding conductors are sized correctly (minimum 10mm^2) with a minimum 10mm^2 Earthing conductor to the Earth electrode. Your main protective conductor (neutralising link) will, if not 10mm^2 be replaced with a 16mm^2 conductor - this would typically have been 10mm^2 before the T&E was replaced in 2017.

But your REC should advise on all of this.

If you don't have an isolator or meter with an inbuilt isolator and contractor's seal (realistically it's unlikely that you will for the age of the installation) then you will need to log a job with the ESB and pay them for the tails to be upgraded. The REC will provide a Cert No. 1 to this end.

I have a feeling that is an emergency light

Industrial type fuse I think. Can't remember the proper name.

It's a Diazed fuse.

Some of these were withdrawn as they were shown to be a fire hazard. They were replaced with Neozed fuses. Now MCBs and RCBOs are the norm, although a switch fuse could still be used for the main overcurrent device where the tails are less than 3 metres in total. Otherwise an MCB with a minimum short circuit current rating of 9kA (which realistically means a 10kA device minimum as no 9kA devices exist) must be fitted in an IP rated enclosure in the Permalli Box.

Great! Thank you for such extended advice!

1 of these beautys, also with heat shrink over to reinstate the sheathing.
In Line Spring Lever Connectors 3 Pole 32A

Tel, Are these the same quality as Wagos?
They look very handy.
