Extension cords are __________________.

• A. Designed only to be used as temporary wiring
• B. Heat resistant
• C. Able to be used safely even if the 3rd prong is missing or improperly grounded
• D. Suitable for use in wet or underwater environments

Answer: (A)

Extension cords are designed only for temporary wiring. They provide a flexible way to reach a power source without changing the building’s fixed wiring, but they aren’t meant as a permanent solution and can be damaged by wear, bending, or moisture. In welding practice, this means use them for short, intermittent tasks, inspect them regularly, and avoid routing them where they can be cut or overheated. They aren’t inherently heat resistant and can overheat if a high-load tool is used for too long. They must be grounded; using one with a missing or faulty ground increases the risk of shock. They should not be used in wet or underwater environments unless the cord is specifically rated for those conditions.
