So I'm thinking of insulating my attic. I have a slab foundation and all my electrical runs through the attic. I know certain hot features (light fixtures, transformers, etc) need a certain amount of clearance around them so they can dissipate heat - that's in the electrical code. Do runs of individual cable, runs of multiple cables (which have to be derated just because they're near other cables) or junction boxes need to be kept clear of insulation too? The derating business makes me think they need space to dissipate heat, but I can't find anything on the topic. Also, if they are on the house side of the summer heat (it easily reaches 140 up there) wouldn't that be better anyway?
