I can usually rationalize a code issue by defining a hazard but my wife stumped me yesterday. She has an old panel that is installed over a 11 1/2" shelf. We both know that is a working space violation but I can't explain the hazard. There is plenty of elbow room around the panel itself and the height is OK. The 11 1/2" shelf still allows adequate approach and even provides a counter top to put your tools on. It is non-conductive (wood with polyurethane).
After seeing it, I am thinking about putting a shelf under mine
