As long as it meets 110.26 I see it as no different than if it were in a garage. We all know how that goes, move car, bicycles, boxes and the lawnmower and you might make it to the panel.I was wondering if putting a panel in a attic that is decked with plenty of walking space, illumiated very good, and has access by stairs would be any violation of the NEC? Only thing I see that could be questioned is if its readily accessible or not.
Whereas some basements get rather flooded from time to time.Some attics get rather toasty. That may be an issue.

I don't see where it would matter if it were a service or feeder supplied panel. You want minimal service conductors entering the structure just like you would on any other floor. It is likely longer distance to grounding electrodes, but there is no limitation on length of grounding electrode conductors.Can you be more specific in describing the panel. Is it a service panel or a remote panel? Where is the main disconnect (Main Breaker)?
Thanks
