Before you buy a new freezer, you need to know what voltage it uses. There are two types of freezers: 110 and 220 volt. Both require a separate circuit for power. Chest freezers need a separate circuit, while upright freezers plug into a standard 110-120 volt outlet.
220 volt freezers are 230 or 240 volt
A 220 volt freezer has a very compact size that is perfect for any home or office and is a great way to add more storage space. It also features an adjustable thermostat, frost indicator, defrost drain, removable storage container, and quick freeze facility.
A separate circuit is required for chest and upright freezers
A dedicated circuit is necessary to safely operate a freezer. A dedicated circuit can accommodate up to four devices. If the circuit does not have enough outlets, a cover plate can prevent another appliance from using the circuit. This is not possible in a house with few outlets.
Chest and upright freezers require separate circuits and use different power sources. They require 120-volt, individually-ground branch circuits and three-prong grounding-type receptacles. Never plug your freezer directly into an existing outlet. To ensure the safety of your freezer, select a unit with GFCI (Ground Fault Circuit Interrupter) outlets.
208 volt freezers are 230 volt
There are two basic types of power for freezers: 230 volt and 208 volt. It is important to know the differences between these two types of freezers before you make a decision. 230 volt freezers are more powerful and can handle more energy than 208 volt freezers.
110 volt freezers are compatible with standard 110-120V outlets
Most refrigerators and freezers can be plugged into standard wall outlets. They have the same outlet and power requirements as electric dryers and kitchen ranges. For details on the requirements of your appliance, consult your manual. Remember, refrigerators are considered non-continuous duty loads. You can place more than one appliance on the same circuit if it does not exceed the breaker’s wattage rating.
In general, most residences use two complementary 120-volt service. This service means that the voltage on one side is 120V and the other side is neutral. A 110-120-volt freezer can be plugged into a standard 110/120-volt outlet.
