LED volt drop- maximum LEDS on 6amp??

[snipersmith87]

I may fire this one to the niec. Be interesting to see their opinion. I think the 18th edition will definitely have something regarding this. I very rarely design a lighting circuit to halogen fittings now. I know you should go worse case scenario but I can't help but think it's such overkill. I don't know anyone that pops to the shop to buy a halogen bulb.

Had this 18months ago with robus LED strip, Could only have 3 60w transformers fitted per B type 6A on one switch pattern and 4-5 on a type C.
When consulting Robus who told me there was no issue with this they said it has 70A inrush for nano secounds.
Also speaking of your issure speaking to the NICEIC the told me a sufficient risk assessment and covering letter stating only designed for LED and only LED to be fitted was acceptable in there eyes.
Depending on the installation method 140m of 1mm may not be suitable for anything more than 1A?

A cable run of 140m with 38 LEDS on??

Do people consider this good practice???

Am I missing something???


Do-able, and will work only due to the smps in the lamps making allowances for the voltage drop.

Probably not. But sometimes you don,t have the luxery of perfect instalations.

No, you got it !

your concerns show that.

Tell them your concerns.
