Working space: The front clearance, side clearance, and height clearance requirements for electrical equipment that provide a safe area for maintenance, inspections, and other work.Section 110.26 of the National Electrical Code outlines the criteria for the clearance area surrounding the junction boxes and other electrical components. According to Section 110.26(A), there must be a 36 inches depth and 30 inches width of clear space. Installations built before the 1978 NEC only require a minimum clearance of 2 ft in front of electrical equipment. The 30-in.-wide rule has been used since the 1971 NEC. Headroom clearance has been required since the 1965 NEC.
The working clearance space includes the zone described in Sec. 110.26(A). Architectural appurtenances or other equipment are not permitted within this zone. Rooms or enclosures containing electrical equipment controlled by a lock are considered accessible to qualified persons [Sec. 110.26(F)]. You must size pull boxes, junction boxes, and conduit bodies large enough so a crew can install the conductors without damaging them. For conductors 4 AWG and larger, you size pull boxes, junction boxes, and conduit bodies per Sec. 314.28. What rule in the code governs how much clearance you need in front of and/or around a standard junction box? Or for that matter any sized pull or junction box?
