Overview
The Occupational Safety and Health Administration (OSHA) requires electrical installations and equipment to be free of recognized hazards that may cause death or serious harm to employees. The equipment must be installed and used according to the manufacturer’s recommendations. It must be mechanically suitable and protected from damage.
All pull boxes, junction boxes and fittings must be provided with covers approved for the purpose. If metal covers are used, they must be grounded. In completed installations, each outlet box must have a cover, faceplate or fixture canopy. Covers of outlet boxes having holes through which flexible cord pendants pass must be provided with bushings designed for the purpose or must have smooth, well-rounded surfaces on which the cords may bear.
