Spotlights and kingspan insulation

[smiffy911]

What do you do when fitting spotlights in celings if the builder is installing kingspan insulation between the joists. I know there isn't really an issue with heat dissapation as I now tend to install LED's. Do you install cables and normal, builder installs kingspan and plates the ceiling, then once plastered cut hole through ceiling and insulation and hope your cables are still there. Or do you have any other ways of installing?

dog's danglies, mate. can even do loop in at first fitting using the connectors supplied with the lighting enclosures. loads of room inside the enclosures.

Thank you my friend, i might just give them a try. I guess being a bit long in the tooth, I am reluctant to change the technology is moving faster than me at the moment

i'm older than you and i can cope with them so i'm sure you can. LOL.

Thought the idea was to avoid running cables in thermal insulation

You're out of date Kingeri

1mm is the minimum for lighting now (1.5mm for everything else).

Then a length of 2-core 0.75mm heat resistant flex (about 9-12" normally) from each JB to each downlight.[/QUOTE]

Fat chance of that with the Gov telling everybody to put more insulation is their lofts.

that's for the circuit T/E. the flex to each light needs to be rated for only 1 fitting.

Now you're just being far too clever :freak:

agreed, or the flex on pendants would be 1mm

Reg number for this? You can happily supply a fixed load with an appropriately rated cable. The 0.75mm flex is feeding only one light fitting.
