I was wrong. It is 6'5" not 6'8". I thought it was the same height as doorways.

Bruce, you're quoting minimum height of "working space". It doesn't back up your claim for the maximum height of panelboards.

Jim P is correct, as per what's in the NEC and IRC.

Could you please reply with the specific sections numbers of NEC and IRC? I have both and would be happy to review to learn more about the error of my ways.

I agree what I posted is the min. working space, which is revalent to the picture in the original post.

Yesterday I inspected a mobile home that the seller had just replaced the rear deck. The service disconnect and main panel/meter are in the yard and this bozo built the deck around the panel. I measured 18" width access to the panel between the two sections of the deck. The seller also claims he got a permit. I'd attach a photo but I don't see a way to do that in a reply...

I have the 2006 IRC here on my PC. The NEC is on my laptop in the car.

IRC E3605.7 Location of overcurrent devices in or on premises.

Overcurrent devices shall:

5. Be installed so that the center of the grip of the operating

handle of the switch or circuit breaker, when in its highest
