There are two things to look for in a commercial freezer extension cord. The first is the voltage rating. Using an extension cord with a high voltage rating can put the freezer at risk of fire. Another consideration is the length of the cord. Make sure you choose one that is at least nine feet long.
An extension cord designed for outdoor use should not be used for freezers. Instead, a cord made for indoor use is a better option. You don’t want an extension cord that’s too short, because it could cause the appliance to blow up and burn everything in the house. Also, it is recommended to choose a cord with a UL listing. A UL-listed extension cord is rated at 15 amps, 125V, and 1875 watts and has a three-prong plug. Make sure the plug is properly grounded and of the correct gauge.
Finally, make sure the cord matches the outlet configuration of your freezer. Typically, a freezer uses a three-prong plug. The third prong is a ground wire. It is a bad idea to cut the third prong, as this would remove the base function. Furthermore, do not plug a freezer into an extension cord, as this is dangerous. A freezer should have a dedicated circuit, which would prevent overloading.
To make sure you choose the right cord for your freezer, you must read the label. Some cords are made of thinner wires than others. The wire gauge is the thickness of the wire that carries the electric current. A lower gauge wire will carry more current without overheating, while a higher gauge will handle more electrical energy.
