Exposed Sockets and Broken Bulbs

DOE-HDBK-1092-98

Portable electric lighting used in confined wet or hazardous locations such as drums, tanks, vessels,

and grease pits shall be operated at a maximum of 12 V, be intrinsically safe, or be protected by a

GFCI circuit.

8.1.8 EXPOSED SOCKETS AND BROKEN BULBS

Exposed empty light sockets and broken bulbs shall not be permitted. This rule is to protect personnel

from accidentally contacting the live parts in the socket and being shocked.

8.1.9 GROUND FAULT PROTECTION FOR PERSONNEL

Temporary power to equipment used by personnel shall be protected by GFCI devices, where

required, or included in an assured equipment grounding conductor program, where permissible. See

NEC Section 305-6, 29 CFR 1926.404(a)(3)(b), Sections 2.7 and 8.3 for further information.

8.1.10 WIRING METHODS

The requirements for temporary wiring for power and lighting purposes include provisions for wire

connections, junction boxes, and overcurrent protection, as well as the use of conductors. See NEC

Article 305.

8.1.10.1 SERVICE CONDUCTORS

Service conductors shall comply with all the provisions of Article 230 in the NEC when they are used

as wiring methods to supply temporary power systems.

8.1.10.2 FEEDER CONDUCTORS

Feeders are the conductors that transmit power from the service equipment to the distribution

panelboard or between the main disconnect and the branch circuit over current devices (circuit

breakers, fuses). Feeders for temporary wiring shall originate inside an approved distribution center,

such as a panel board, that is rated for the voltages and currents the system is expected to carry. Some

equipment is manufactured specifically for temporary use.

Feeders can be run as cable assemblies, multiconductor cords, or cables with two or more conductors

each with their own insulations, run together in the same cord or cable.

8.1.10.3 BRANCH CIRCUIT CONDUCTORS

Branch circuits are the conductors between the last overcurrent device in an electrical system and the

outlets, such as receptacles, lighting outlets, and outlets for electrical equipment wired directly into

a circuit. Branch circuits for temporary wiring shall originate inside an approved panelboard or

power outlet that is rated for the voltages and currents the system is expected to carry. As with feeders,

branch circuit conductors can be contained within multiconductor cord or cable assemblies.
