I hope I can ask a not-specifically-NEC question here.

It will be directly adjacent. With the earlier mentioned NEMA 3R enclosure - there will not be any KO's in the top or sides (maybe near bottom on sides) and may or may not have KO's in the bottom. Hard to maintain a raintight rating if you have KO's in the top or high on the sides. The concept behind explosion-proof electrical enclosures is that if there is an electrical arc inside the enclosure and this ignites explosive gases INSIDE the enclosure that the escape path for the hot gas from the inside of the enclosure to the outside will cause sufficient cooling of the gas so that it will not ignite the surrounding air .
