Evening all,
Further to my previous post I've decided to use 240v downlights in the utility room.
Just wondering what the best, well, correct, way to connect these up?
The lights are double insulated and have a little junction box attached with two heat resistant flex's from the little junction box to the light. Now, should I just run 1.5mm cable to each light in sequence, from one to the other but with the earth joined in a choc block (basically meaning that all but the last light in the chain has two conductors in each terminal)?
The alternative I was thinking about was to run a short length of two core flex from the junction box attached to the light to a small 3 terminal junction box and have the 1.5mm circuit cable connect in this juncion box by each light.
How do you do it? What is generally best practice?
Another thing making me nervous is the amount of insulation up in the ceiling which I suspect is a contributing factor in the melted wiring situation on the old 12v lighting in there. I've cleared as much of it out as I can, about 6" around each hole so I think all connections should be OK but I'm worried about the cable run between each light.
As I can't remove the insulation between one light to the next, I was wondering if it is going to be OK if I can make sure the cable lays on top of the insulation rather than sitting under it? I'm using 1.5mm t&e. The lights are 50w each and there are 5 in total so 250w altogether. The last light in the chain will be about 4m away from the first. As I see it, the cable will be carrying just over 1 amp which under ordinary circumstances would be fine for 1.5mm but what de-rating effect ould the insulation have?
Cheers
Don
