Choose the right extension cord for the job, and use it as specified. Extension cords can overheat and cause fires when used improperly. Overheating is usually caused by overloading or connecting equipment that consume more watts than the cord can handle. Damaged extension cords can also cause fires. Extension cords should only be used temporarily. Unplugging the cords when not in use.
Overheating or Damage
Overheating can occur at the plug, at the socket, or over the entire length of the cord. Hot plugs and sockets are often caused by deteriorated connections to the cord’s wires.
Look for visible signs of excessive wear or damage to the plug, sockets or insulation.Replace damaged extension cords
If any part of the extension cord is hot while in use, it is a warning sign that it may be overloaded. Check if the extension cord is properly rated for the products that are plugged into it. Also, inspect the cord along its entire length to ensure it has not been damaged.
Do not overload your extension cord by using it to power appliances beyond its capacity. You can check its capacity, or rating, by looking at the tag on the cord or its packaging.
Protect Extension Cords from Damage
Do not run extension cords under carpets, through doorways or under furniture.
Only use an extension cord outdoors if it is marked for outdoor use.
Never alter a cord to change its length or perform inadequate repairs such as taping up damaged insulation. Do not trim, cut or alter the plug blades in any way. Unplug an extension cord when it is not in use. The cord is energized when it is plugged in and can overheat if shorted.
Discard Older Extension Cords
Discard cords that are old and/or are missing important safety features, including safety closures, polarized blades and a large plug face that covers the outlet’s slots and is easy to grasp to unplug.
Extension cords should be at least 16 AWG, unless they are 18 AWG with fuse protection. AWG refers to the size of the wires in the cord. The wire size is imprinted on the cord’s surface.
