As a general guideline, it is generally a good idea to replace extension cords that have become brittle, worn, or damaged for safety reasons.
Extension cords that are worn or damaged can pose a serious safety hazard, as they can cause electric shock, fires, and other accidents. Worn cords can also cause electrical appliances to malfunction, which can lead to damage or cause injuries.
Replacing damaged or worn extension cords with new ones that meet current safety standards is a simple way to help ensure the safety of your home and those who live in it. When purchasing a new extension cord, be sure to choose one that is the appropriate length and gauge for the intended use and to use it according to the manufacturer’s instructions.
Remember, extension cords are intended for temporary use only and are not a substitute for permanent wiring. If you find yourself relying on extension cords regularly, consider having additional outlets installed by a qualified electrician.
