Equipment for General Use - Lighting Fixtures, Lampholders, Lamps, and Receptacles |
||||||
| Fixtures, lampholders, lamps, rosettes, and receptacles may not have live
parts exposed to employee contact during normal operation. However, rosettes, and
cleat-type lampholders and receptacles located at least 8 feet above the floor may have
exposed parts. Portable type handlamps powered through flexible cords shall be equipped with a handle of molded composition or other material approved for the purpose, and a substantial guard shall be attached to the lampholder or the handle. Screw-shell type lampholders shall be installed for use as lampholders only and must not be used with screw-base socket adapters. These adapters screw into the existing lamp socket and convert lampholders into receptacles. These adapters are not permitted because equipment grounding connections cannot be made through the two-blade adapters and because the fixture has been designed only for lighting. Only weatherproof lampholders may be installed in wet or damp areas. Unprotected lampholders might allow moisture to enter the lampholder socket, creating an electrical shock hazard. |
