I have a homeowner who wants to install his residential loadcenter in the back wall of a 12inch deep broom closet. I quoted him the requirements of 110.26, which I assume also applys in residential. I told him 3 feet in front, which is theoretically possible with the door open. Width of panel or 30", whichever is greater, which would mean a 30" door. Nothing stored in the dedicated space from floor to ceiling, which everyone knows this will get violated! I told him I did not recommend it, but is there anything in the code that prohibits this placement? There will be no clothing stored in it. Thanks in advance.
