Wiring in downlights - do they have to be in parallel??

[telectrix]

Yes have checked the load...is 1200 w on a 5amp circuit so just about ok I think (bearing in mind they wont all be on at once and I plan to remove some other lights in future)

Anyway i want to wire it like this where D is the downlight and W is the wire. The JB is right in the centre

D.........D.........D
W........W........W
W........W........W
DWWWDWWWD
W........W........W
W........W........W
D........D..........D

was yor kast job at bletchley , or do you have an enigma machine?

Think I've seen it all now:54:

im not sure why people worry about the way they wire lighting it doesnt matter if you have spurs off to a few lights or daisy chain because as long as the protective device is rated less than the current carrying capacity of the cable and the circuit is calculated to take the lighting load you cant go wrong

Well why's he askin' how to do it in code form then?

Makes it a pain in the 4rse to do yer voltage drop calcs though

How can something so simple, be made to look so difficult???

Perhaps James is in the wrong profession, he should of seriously considered Politics!!!

yes perfect practice would be to wire lighting in a straight line from light to light but as he said hes adapting an EXISTING LIGHTING CIRCUIT....??

Lets put this in simple terms. Yes, you have to wire them in parallel. Whether that is daisy chained, spidered out or whatever else you can come up with, each light will need the same voltage. In series, each light on an 240V system will have 26.6V, making a very dim view if the situation. Pardon the intended pun........
