Which statement regarding extension cords is correct?

• A. They can be used for permanent wiring
• B. They should be used for all outlets
• C. They should be used as the primary power source
• D. Extension cords can only be used for temporary, portable pieces of equipment

Answer: (D)

Extension cords are meant for temporary, portable use and should not be treated as permanent wiring. Using them as a fixed power source can lead to overheating, voltage drop, and fires, especially with high-wattage or continuously used equipment. For permanent power, install proper outlets wired into the building, and if outdoor use is needed, choose outdoor-rated cords and keep them in good condition. Avoid daisy-chaining cords, running them through walls or under carpets, or using damaged cords. In short, extension cords are for temporary, portable equipment only.
