I am doing the electrical design on an apartment building with very tiny apartments. I thought that I read that there was a code change preventing panelboards from being placed in restrooms in residences. I cannot find it now - so was I dreaming? The code clearly indicates that there should be workspace in front of a panelboard, and we all know that a dweller of a tiny apartment isn't going to respect that at all. Where do you put a panelboard in an apartment designed with no halls?
