Section 110.26 specifies the requirements for the clearance area around electrical equipment, including junction boxes. Section 110.26(A) requires a clear space of at least 30 inches wide by 36 inches deep.For equipment designed for floor mounting, clearance between top surfaces and adjacent surfaces shall be provided to dissipate rising warm air. Electrical equipment provided with ventilating openings shall be installed so that walls or other obstructions do not prevent the free circulation of air through the equipment.In addition to other requirements in this section, the following requirements apply to pull and junction boxes for systems over 600 volts, nominal: 1910.305(b)(3)(i) Boxes shall provide a complete enclosure for the contained conductors or cables. The rules for pull boxes, junction boxes, and outlet boxes cover five areas. In summary: Minimum size [314.28(A)]. These requirements constitute most of Sec. 314.28.

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)]. A good example is a junction box installed in an attic with no working space or clearance space required by 110.26 (A) for proper installation. This installation is acceptable because there are no exposed live parts to be worked on while energized. 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.There is not a standard electrical code requirement that gives the minimum clearance distance between an electrical panel and a plumbing fixture, but you can figure a minimum distance from plumbing to panel by at least following the working space requirements.
