§ 2340.13. Mounting and Cooling of Equipment.

(a) Mounting. Electric equipment shall be firmly secured to the surface on which it is mounted. NOTE: Wooden plugs driven into holes in masonry, concrete, plaster, or similar materials are not considered secure means of fastening electric equipment

For equipment designed for floor mounting, clearance between top surfaces and adjacent surfaces shall be provided to dissipate rising warm air.

(c) Cooling. Electrical equipment provided with ventilating openings shall be installed and maintained so that free circulation of air through the equipment is not obstructed.
