Extension cords are designed only to be used as temporary wiring. Which statement best reflects this claim?

• A. True
• B. False
• C. Only if the third prong is present
• D. They are suitable for wet environments

Answer: (A)

Extension cords are intended to provide a temporary electrical connection from a wall outlet to a portable device. They aren’t designed to replace fixed wiring in a building or to stay in place long-term. If used as permanent wiring, they can overheat, degrade insulation, and pose a fire hazard, and electrical codes generally require proper permanent outlets instead. Grounding (the three-prong plug) improves safety but doesn’t change the cord’s temporary nature. Use the correct gauge and avoid daisy-chaining cords or running them through walls or damp areas; for outdoor use, choose cords rated for outdoor use, but still treat them as temporary solutions rather than permanent wiring.
