I''m having an argument with an inspector about installing panel boards in a space beneath stairs in a commercial building. All working space clearances are met, access requirements are met, the space
Are these stairs in a rated exit enclosure? Do these panelboards only serve stair related loads? There are a couple of requirements from NFPA 101 and the 2020 NEC that prohibit installing
Aside from what I have mentioned, the electrical panel height from the floor is also strictly regulated by the National Electrical Code. Particularly, the electrical rule book states that a panel
___ NEC 230.9(A) – Open overhead service conductors shall have a clearance of not less than 3 ft. from windows designed to open, doors, porches, balconies, decks, stairs, or similar.
