service panel mounting

[bertronix]

Does anyone know of any NEC codes relating to mounting a service panel on a ceiling, or overhead? I can see the difficulty involved with working on a panel in this location! but is it against code? Thanks, Bertronix

Bertronix, I don't see a section in the 99 NEC that would directly prohibit it. I think it would fall on the manufacturer's installation instructions(listing?) 110-3(b).

I haven't checked the book but it needs to be readily accessable.

I'm still a student of the code book but I think these apply 230.70(A), 230.70(1), 230.91.

Re: service panel mounting

I can't seem to find the code that states that the service disconnecting means must not be taller than 6' in height, but check out 110.26(A)2,3, and (E). If you follow those rules of below 6', nothing extends farther than 6" in front of the panel 6' beyond panel, for the service space to the ceiling or 6' rule. I wouldn't have a problem with it as long their was a reason, then again the ole trusty authority having jurisdiction!! Always an easy cop out huh!! lol

You should look at 404.8(A) for starters.

Bertronix:
It would not be practical or safe to install the panel on the ceiling, but as far as the code, (1) check the mfg's listing on the panel, and (2) look at 2001 cec 380-8(a)for max height of breakers above the floor or working platform. David

Re: service panel mounting

there was a code change for the 2002 NEC to clarify the disconnect means must be installed vertically unless impractical, then horizontal is ok. At an IAEI meeting, a CMP member explained the orginal meaning of horizontal meant mounted on the ceiling (from the 1920's), and not how we visualize it today.

Its perhaps not prohibited, but I would check with your AHJ. On a ceiling is not where I would look for a disconnecting means.
