The pipes do appear to be beyond the dedicated space. If you hang a plumb bob from the closest pipe will it clear the panel cover?


I agree you really have to hold your nose to say it is OK but it might be legal.


Fortunately you are not code inspectors, you can point out things that are on the edge of being legal.

Some more opinions by electricians and inspectors over on

PS: What about the cabinet located directly on the concrete? Most installers use some form of weatherproof plywood.

Personally, I see no violation where the water pipes are considered, but do wonder if a leak would not spray onto the panelboard. The initial design could have routed the pipes a bit further away.

Please tell me more about the reference: IRC3305.3

Joe, yes, the panel board was supported off the wall. Here is what the IRC reads.


IRC3305.3 Clearance over panel boards. A dedicated space directly over panel board that extends from the panel board to the structural ceiling or to a height of 6 feet above the panelboard, whichever is lower, and has a width and depth equal to the equipment shall be dedicated and kept clear of equipment unrelated to the electrical equipment. Piping, ducts or equipment unrelated to the electrical equipment shall not be installed in such dedicated space.


I will try and get some measurements from plumbing lines, and take a better picture over the panelboard. I told the client just to make sure the electrician knows about the plumbing, seeing how it could have been installed after him, and also the code inspector will have the final word if it's a violation.

It sure looks like they tiptoed inside the lines. It looks like an inch or so “out” in every direction.
