Could someone do me a simple wiring diagram for the easiest way to wire these up. Existing light has terminal block with circuit cable (black,red and earth) in and out (6 wires) plus switch cable (2 lives and earth). Should I replace this with a four way junction box, make same connections, then run live neutral and earth from junction box to first downlighter then second and so on ? Does the cable have to loop back in to the junction box or can it finish at the last downlighter like a spur? Also I have 2 zone one lights which have an earth terminal and 2 zone three which don’t, why is this? Both fittings are metal. Should I fit an earth to the zone 3 lights? they are from Wickes if that helps. Thanks in anticipation

Thanks in anticipationI'd be interested to know the answer to this one too as the downlighters in my new house (installed by previous owner) appear to have two different installations:
1) junction box to set of lights (jb - 1 - 2 - 3 - ...)
2) junction box to set of lights and then back to junction box (jb - 1 - 2 - ... - jb)
They can't both be right can they?

well I think they both could be right, but probably in different circumstances. I just want to know the correct way for my situation. Just to add my downlighters are mains voltage not LV
can anyone answer the original question, is it just too stupid, not interesting enough or what, are my flies open or is it because I’m not an electrician? Thanks againCan't comment on the earth but would have thought if the lights have earth connections they need earthing. If they don't, then they don't.
The lights can just be wired as a spur or as a star. Or both 2 feeds to 2 lights each e.g. if the JB was in the middle of the 4 lights.
Wiring back to the junction box probably isn't wrong. It is over engineered and could hide a fault in one of the cables but as this wouldn't stop the light from working who cares.
