recessed light and drop ceiling


I am putting recessed can lights in a small drop ceiling. I have a junction box in the ceiling that is metalic, which romex is fed to it from the switch in the wall. The box is tied to ground of course with a ground pigtail

Now, from the metal junction box to the recessed light, should this be armored cable, or do romex and somehow staple it to the joists to keep it from moving too much? the joists are about 9 inches from the top of the ceiling right now.

Also, the lines for lighting are all 12 gauge, do I need to use 12 gauge from the junction to the two can lights? or is 14 gauge alright? I know you aren't supose to change gauge on a circuit generally, but this is an end fixture, not a branch line. Nothing else will feed off it.

This is going to have two to three (max) 75 watt can lights on the switched line.

Thanks!

If the circuit is wired with all #12 and on a 20A breaker then you must use #12.
Using #14 and changing the breaker to a 15A is dumb.

That's what I thought, breaker is already 20 amp, all the lines are 12 gauge coming from that breaker

what about the cable type? I assume romex (NM) is allowed if boared and stapled... or should it all be armored (AC) cable?

Type NM cable should be fine.

Is this NEC wording?

Yeah, that was the ROP I was involved in.
