I'm getting ready to put in some recessed lighting. I'll have six lights in a rectangular room: one on each short end and two on each long side. The access above makes it easiest to run all the wires across the room above the ceiling to one long side and hook up the switch in one corner. Something like:
S| || || | O| O| | | | | | | | | | O | | O | | | | O O
(That's clear in a fixed-width font.)
My question/problem is, how many wires can I put in one junction box? The most natural arrangement with a minimum of boxes seems to be to get three lights to one junction box, three to another, then take a lead from each of those to another to connect to the switch. With a big enough box, is this OK? I can't imagine a wire nut big enough for four leads. Do I have to do 2 and a jumper, 2 more and a jumper, then the two jumpers together? For four grounded wires, that's a lot of wire nuts in one box.
