Pavilion Wiring: Octagon Boxes Legal?

I have to wire a number of pavilions. Is it acceptable to use octagon boxes and porcelain sockets or do I need to use the aluminum bell boxes and vapor tight fixtures? The ceiling is getting finished with a plastic material. I am using 12-2 UF-B if it matters any.

I see no reason a standard 4" octagon box wouldn't be acceptable as long as they aren't subject to rain.

I agree. I haven't seen anything other than octagon boxes and MC/UF etc cable on a wide variety of pavillions, from ones as small as 25x10, to 50x200 and larger.

When the wiring is under and in the roof space, it's essentially protected from even blowing rain.

Watch your box fill. My calculations (19 cubic inches) allow one incoming (feed) cable, and at most two outgoing (continuation) cables (6 12 gauge conductors) allowing for the grounds (1 point) and cable clamps (1 point).

(If you go over, you could get an extension ring to go on the rim of the box and you attach the light fixture to that.)

I always find it hard to fit more than two cables into an octagon box.
