Section/Paragraph: 110.31 Enclosure for Electrical Installations (D)
Deleted Text
(D) Enclosed Equipment Accessible to Unqualified Persons. Ventilating or similar openings in equipment shall be designed such that foreign objects inserted through these openings are deflected from energized parts. Where exposed to physical damage from vehicular traffic, suitable guards shall be provided. Nonmetallic or metal-enclosed equipment Equipment located outdoors and accessible to the general public shall be designed such that exposed nuts or bolts cannot be readily removed, permitting access to live parts. Where nonmetallic or metal-enclosed equipment is accessible to the general public and the bottom of the enclosure is less than 2.5 m (8 ft) above the floor or grade level, the enclosure door or hinged cover shall be kept locked. Doors and covers of enclosures used solely as pull boxes, splice boxes, or junction boxes shall be locked, bolted, or screwed on. Underground box covers that weigh over 45.4 kg (100 lb) shall be considered as meeting meet this requirement.
Substantiation:
"nonmetallic or metal-enclosed" is meaningless as it means everything. "considered" is an unenforceable term according to NEC_StyleManual_2011.pdf 3.2.1. "shall be considered as meeting" can be more directed expressed as "meet".
