Hi,

Quick Q from a newbie. I had a NICIEC registered electrician install an isolation switch and extractor fan in my downstairs bathroom. I’m now replacing one of the down lights and found what is a surprising mess of wires in the false ceiling, all joined together with a terminal block (centre is neutral, left and right are live).

The grey cable leads to the isolation switch and the terminal block has been installed by the electricians. They’ve twisted the earth wire onto an existing twisted arrangement.

Is this safe/correct? I found it surprising from an Australian perspective but am open to being told that this is how things are done in Britain.

If this isn’t right, what should I do before adding the downloght? Put the terminal block in a junction box? Solder then sleeve twisted earthing wires?

My wife is back in an hour and I want everything back in the ceiling then, so prompt responses appreciated!

The connections need to be enclosed in a suitable enclosure i.e a junction box, which will have to be maintenance free if it isn’t accessible and that is not an acceptable way to joint CPCs (earths) The NICEIC has a platinum promise so call up the guy who did this and tell him you’ll be sending pics to the niceic if he doesn’t get his butt back and sort it the way it should be done, also if he refuses to come back and sort it. Get on the phone to the NICEIC and make sure they send out someone who will do it right, their platinum promise thing means they will send someone else to do it for free if the original contractor won’t/can’t fix it.

Edit; after another look I have spotted some copper showing on the black termination to the far right for which there is no excuse and also the lack of proper identification of the cores i.e sleeving not to mention the obvious lack of sleeving for the CPCs

And personally I don’t think you should add anything to it until that mess has been rectified.

I can only apologise for a fellow spark has done .and you have the write to complain .send me his details and I will make sure that my big boots are on to kick him or she up the A77.
I wouldn’t call the nugget that did this a spark any day of the week. I didn’t realise you have to write to complain that’s good to know for the future.

OP did you receive any sort of certificate for the work that had been done?
 
I would suggest that those connector blocks have been there before your electrician was it looks like the 3 white cables have at one time been a lighting point. However your electrician should not have added his new cable into that lot in that way. For the sake of a small enclosure a bit of sleeving and a few MF connectors it could have been done correctly.
