What is the general rule for extension cords in permanent installations?

• A. They are for temporary use only and shall not be used as a substitute for permanent wiring
• B. They may be used as permanent wiring if rated for outdoor use
• C. They can be used indoors for continuous service
• D. They should be replaced with fixed wiring immediately

Answer: (A)

Extension cords are intended for temporary connections and should not be used to replace permanent wiring. They have limitations in insulation, current capacity, and protection, and can overheat, be damaged easily, or create shock or fire hazards if used for extended periods. Even cords labeled for outdoor use remain a temporary solution and are not a substitute for fixed outdoor wiring. For lasting or permanent needs, install proper fixed wiring with mounted receptacles on the circuit.
