Hi.

I’m a non-electrician looking for some guidance. I hope you can help.

My mum has had two new down lights installed in the bathroom. I’m also putting insulation around and over the lights. I’ve got a down light protector for each light but I have a question about the wiring.

Firstly, in the picture attached, you can see the inner wires on the connection that the electrician made. I just wanted to know whether that is safe? That connection will be right in the insulation so I wanted to make sure it isn’t a fire risk.

If it is would it be ok to just wrap that connection in electrical tape to make it safe or do I need to get an electrician in?

Secondly, is it ok to have a light so close to a beam? I’ve got to cut the down light protector to fit over the light and beam.

Thanks for your time and help. I appreciate it.

Insulated and sheathed cables entering an electrical enclosure. the outer sheath should enter the enclosure, you should not be able to see the insulation without removing the cover of the enclosure, in this picture you can see the insulated cores entering the JB, this is unacceptable as is the JB as it is not fixed nor is it MF
 
1. if you refer to the inner insulation exposed on the black flex, that only 12V and , although rough) poses no danger.
2.having a downlight right next to a joist is again rough, but as LEDs don't get hot, again i can see no danger.
The 240V cables are a mess, but again, apart from the tape next to the junction box may conceal something nasty,
If the downlights are the ones i think they are, they are designed to have insulation directly on top. are they JCC V50's?

it's accessible pete, so does not need to be MF.

What does MF mean?

Well I couldn't get to that JB Tell, so it's inaccessible to me, but I see what you mean and agree with you.

Thank you so much for this reply. I found the website of the company and light you mentioned that looks identical to my light.

It has pictures of the wires exactly as my wires are installed. I.E. with the inner sheaths showing. So it has put my mind at ease.

Thank you so much for your help. People like you make the world better!

I just need to confirm that they can go directly under insulation and everything will be perfect. I’ll have a look in their website to find that out and maybe send an email to the manufacturer.

Thanks again, you’ve helped a huge amount.
 
Hi - those old style circular junction boxes don’t have internal strain relief, ie no cable clamps. So the junction box and cables were intended to be clipped onto the building infrastructure to minimise movement, which may otherwise cause the junction to become unreliable (I think this is covered in Reg 522.8.5). So I would expect myself to tidy that snakes wedding and update to a modern MF style junction box that includes strain relief, if only from a reliability perspective.

Fix some timber across the rafters, screw JB To timber, clip cables securely to timber, make off joints, but silly me they don't teach that at Sparky School do they??
