I've got a situation on a 1st floor where because of the double layer ceiling on top of some track built off the joists for noise reduction it was more practical to go with 4 squares and deep plaster rings for certain light locations. Well the p rings came in as single gang w/6-32 screw holes. I'm of the opinion that these are no good for hanging lights and we should reorder round p rings, but am having a problem coming up with the article for that. 314.27(a) only says the box shall be designed so a luminaire can be attached. that's a bit vague. I thought sure you needed 8-32s for supporting fixtures with the box. Can someone point me in the right direction here?
