NEC 210.52(E)(2) requires a receptacle to be installed for every multi-family dwelling unit located on the ground floor ONLY of a multi-family building. Presumably this is supposed to be on the tenant's power. Does anyone know what the intention is or what purpose this receptacle serves and why would they only be required on the ground level? Out of all the apartments i've done, i've never ran into this and out of all the apartments i've been to, I dont recall ever seeing this. Seems like an odd code.
