Life Safety Tip from Bob Trotter, BS, MCP
Temporary
Electrical Wiring
According to NFPA 70, National
Electrical Code, 1999 edition temporary wiring is defined as “Approved
wiring for power and lighting during a period of construction, remodeling,
maintenance, repair, or demolition, and decorative lighting, carnival power and
lighting, and similar purposes”. The NEC requires temporary wiring to be
removed immediately upon completion of construction or purpose for which the
wiring was installed.
Learning Objective: To know that temporary wiring must be removed at the end of a project.

Temporary electrical power and lighting during periods of construction, alteration, and rehabilitation commonplace in the built environment. On a regular basis life safety surveyors are discovering temporary electrical wiring for power and lighting located above suspended-grid acoustical tile ceilings. In many cases the temporary wiring is supported from sprinkler piping which is not permitted by NFPA 25, Standard for Inspection, Testing and Maintenance of Water-Based Fire Protection Systems or The Joint Commission. Regularly the wires extend through walls and are often cut leaving exposed conductors that are potentially energized and creating a fire and life safety hazard.
