Heat Resistant Cable Inside Light Fitting

Anonymous user 23/02/2024 - 3.37 PM

Hi I hope someone here can advise me. I just bought a 60W rated bulkhead light fitting. It is rated for outdoor use but I intend to use it indoors to replace an existing fitting in a hallway . The light fitting has no wiring or terminal block inside but was supplied with three pieces of heat-resistant sleeving. The instructions - such as they are - are just a diagram showing a round cable of some kind to the fitting and indicating that the sleeving should be used to cover the three individual wires. So my question is: Is it really sufficient just to sleeve over the pvc and wire it to the ceramic lampholder (and of course the earth point)? Or did the manufacturers assume it would be supplied via a heat resistant 3 core cable? Alternatively, I could use the terminal block and heat resistant tails from the old fitting, though this is ten years old. The light fitting claims to be CE approved but... Glad to hear opinions on this. Regards Andy

Are you a tradesperson and able to answer this question?

Heat resistent sleeving in bulkhead lights was common place years ago when tungsten filament lamps were used because of the heat generated by the lamp in very close proximity to the wire connections. It is less of an issue these days where LED lamps are used as these lamps do not give off heat like the old lamps did. I would recommend something like 1.00mm2 flex to connect on to the ceramic lamp holder with the wires sleeved with the sleeving provided. Just ensure you are careful to connect the wire without any 'whiskers' of copper or bare copper showing and it will be fine.

If the manufacturer has supplied with its product heat resistant sleeving designed to protect the basic insulation of the associated conductors from heat, then yes it would be a great idea to use them. Regards, Carl.

You don't really need the sleeving if you use an LED lamp, however it can't hurt to use it either.

Without properly seeing it, I I would have to say you should use some heat-resistant single wire sheathed with the 'heat-resistant sleeving' back to a terminal block and then pop in some 3 core flex appropriate for the job. With regards to the LED nature of things that we see these days. You wouldn't necessarily need this heat-resistant shiz but that is assuming that it will always have an LED lamp installed in it. Additionally, if the manufacturer has supplied it then it probably should be used. As you say, it was probably meant to come pre-wired but just your luck that you've got the 1 in 100 that isn't. Hope that helps.
