Which statement describes extension cords in permanent installations?

• A. They are for temporary use only
• B. They may be used as permanent wiring if installed by a licensed electrician
• C. They are acceptable for all outdoor use
• D. They should be kept unplugged indoors

Answer: (A)

Extension cords are meant for temporary, portable power, not for permanent wiring in a building. They’re designed to connect a portable device to an outlet for a limited time, and using them as fixed, lasting wiring bypasses the protections built into proper electrical installations. This creates risks of overheating, insulation damage, moisture intrusion, and physical wear, which can lead to fire or shock hazards. Because of these safety concerns, extension cords should not be used as permanent wiring, even if someone claims to wire them in temporarily or with a licensed electrician. For a permanent installation, fixed wiring and outlets must be installed and wired into the building’s electrical system, and outdoor use should employ properly rated outdoor outlets and protective enclosures. The other statements describe scenarios that don’t align with the intended, temporary nature and safety role of extension cords.
