Article 110.26(E) of the NEC states that you need a dedicated equipment space above panels, switchboards or motor control centers that is either 6 feet in height or to a structural ceiling whichever is lower. Why is this space required? Is it for future access to the top of these pieces of equipment? I have an installation that has ductwork only about 8 inches above 2 switchboards which are my normal and emergency service entrance switches. The feeder conduits come out of the bottom and no more feeders will ever come out of either switchboard. Why do I need the clearance on the top?
