Type of cabling supplying led vapourproof fittings

Hi all

ive a quick query I wouldn’t mind your opinion on. I have some ansell Tornado led vapourproof fittings to fit soon. They will be surface mounted using the supplied metal clips and the wiring will be pvc conduit and single stranded cable. I intend to enter the fittings through the end with a bit of flexible conduit and continue the stranded cable inside the fitting to the terminations which are about half way along the fitting. My query is that when the fitting is all assembled, the stranded cable will be resting on top of the metal ‘tray’ containing the led strips and driver which both actually give off quite a bit of heat after a while. Does ordinary stranded cable withstand a decent amount of heat? Previous fittings that I used had the terminations at one end so it wasn’t much of a problem but with this newer design, the incoming cable has to go half way up the fitting. I want to loop in/out inside the fitting instead of a plug in ceiling rose arrangement and don’t fancy having to put heat resistant sleeving  on each bit of stranded cable. Will the stranded cable survive lying on the metal tray long term?

Thanks in advance

  • If the LEDs, or their drivers, get hot enough to overheat 70C PVC cable, then they aren't going to last very long.
