I am installing ultra thin recessed light in the basement and it comes with a very small metal box (probably 2x4 in in size). Due to the old wiring of the house, there are 5 wires coming in totally: power to light 1, power to light 2, 2 switches, and the light itself. It's going to be very "crowded" because the wire nut will have to fit like 4-5 wires.
I would like to "connect" everything" outside of the ultra thin metal box and only leave 3 wires (white, black, ground) coming into the box itself.
I am thinking of a few options:
Use an electrical box and connect everything in there but leave 3 wires out to go into the recessed box. Then close the box with a lid and just sort of "throw" it up in the ceiling somewhere (no screw or mount into joists).
Tear up the ceiling to find a joist and install a Round Hard-Shell Ceiling Box then connect everything there. However, the hard part is to connect existing wiring since some are not long enough. I may have to create additional lumber support. Either that or I have to use the ceiling box that has a metal bar to mount both joists. Regardless, this is major ceiling work and drywall fixes.
I am leaning toward Option 1 as I doubt there is any unforeseen issue. What are your thoughts?
