6.7.2 Temporary Electrical Installations and Uses During Construction Activity

The following guidelines are to be considered the absolute minimum requirements to be supplemented by requirements of all applicable codes and standards for such work:

1. Wiring and Branch Circuits
   1. Must be protected by a proper amperage overcurrent device such as a fuse or circuit breaker.
   2. Must be located so as to prevent physical damage to the wire conductors.
2. Lighting
   1. Temporary lights must be located at appropriate distances from the respective lighted work area(s).
   2. All temporary lighting fixtures must be protected from accidental contact or breakage.
   3. Temporary lights shall not be suspended by their electric cords unless they are designed for this type of installation.
   4. Portable electric lights used in wet or potentially wet locations must be either low voltage type (12 volts or less) or protected by a GFI (ground fault interrupter).
   5. Portable light cords designed with (2) conductors are not to be used as extension cords to supply power tools.
3. Extension Cords
   1. Must be visually checked before each use and periodically while in use to assure their original integrity is maintained. Cords with cuts, breaks, deep abrasions, etc. shall be taken out of service immediately. Repairs to extension chords shall only be performed by qualified, licensed electricians.
   2. Are not to be hung across walkways, work areas, stairways, etc. where they create possible tripping hazards, or where they might be damaged by equipment or traffic. Cords may be hung overhead with sufficient minimum clearance or rerouted under or around walkways and work places. Cords crossing vehicle traffic areas may be covered or encased by suitable material to protect them that is designed for this purpose.
   3. Must not be fastened, or attached with any type of conductive material such as nails, metal wire, staples, etc.
   4. Must not be allowed to lay in wet or potentially wet areas.
   5. Must be of the 3-wire type when used with portable electric tools and appliances.
