FAQ:

Q: Is it safe to use an extension cord with a refrigerator?

A: GE strongly recommends that an extension cord not be used with a refrigerator due to the potential safety hazards under certain conditions. However, if an extension cord is used, it is absolutely necessary that it be a UL® listed 3-wire grounding appliance extension cord, and that the current carry rating of the cord be a minimum of 15 amperes.

Q: What is an outdoor extension cord?

A: Extension cords are classified as either indoor (S) or outdoor (W) use. Although they may look similar they are indeed different. The insulation, or jacket, of an outdoor extension cord is composed of a more durable material, designed to withstand temperature changes, moisture, and in some cases even chemicals.

Q: What is electrical extension cord?

A: An extension cord, power extender, drop cord, or extension lead is a length of flexible electrical power cable (flex) with a plug on one end and one or more sockets on the other end (usually of the same type as the plug).

Q: What is an extension cable?

A: An extension cable is an electrical cable that is connected to the cable on a piece of equipment in order to make it reach further.
