406.4(E) states: "Receptacles shall not be installed in a face-up position in countertops or similar work surfaces". Is there a similar rule for other environments? I was in a testing facility/lab portion of an industrial building today that contained numerous workstations with receptacles placed in the face-up position. A member of the maintenance crew said a previous electrician informed him that having receptacles mounted in this fashion was against code. I informed this person that the electrician was wrong and that the code sited only applied to dwellings. Was I wrong?
