Can I put a 100 amp sub-panel in my attic? My attic has pull down stairs and is unfinished. I was hoping I can put a sub in my attic to make it easier for numerous runs I have to do on the second floor. I want to be up to code and do not want any issues with homeowners insurance. Thanks, mike

A panel in the attic is fine, as long as it is "readily accessible" which the pull down stairs offers. If a ladder is needed to access a space, a panel cannot be located there.
