Can I use an extension cord for a freezer?

Plug the extension cord into a grounded three-pin receptacle if the power cord on the freezer or refrigerator has a ground pin. Never use an extension cord that has been damaged.The power cable in a freezer or refrigerator has a pin on the floor, so you need an extension cable of 3 domestic wires, and you need to connect the cable in a container of three pins on the floor.Never use a damaged extension cable.
