Electrical requirements and switch sizes for refrigerators are a single 115 or 120 volt well grounded circuit protected by a 15 or 20 A circuit breaker or time delay fuse.
In the United States, the NEC does not require a refrigerator in the kitchen to be on a dedicated circuit. A refrigerator can be connected to one of the at least two circuits necessary for the derivations of the small household appliance.
Power Consumption At 110 volts, a 750 watt device needs 6.8 amps to operate. A refrigerator uses about half the power of a typical 15 amp circuit and more than a third of a 20 amp circuit.
However, a 20 amp package isn’t needed unless it’s the only one in the circuit. Since a two-sided container counts as two, a 15 amp container is fine. You can plug a refrigerator into any electrical outlet.
It is not possible to use a refrigerator and a microwave on the same circuit. According to the 2020 version of the NEC, it is not allowed to use a microwave oven and a refrigerator on the same circuit because each of these devices requires its own circuit which is not shared by any other device or lamp.
A normal household refrigerator is plugged into a regular outlet. The socket provides 110 volts to power the device. Most building regulations require the refrigerator to be connected to a special circuit. This means that a switch in the electrical panel only controls the device and nothing else.
All commercial buildings / kitchens must have a differential switch for refrigerators. If the circuit feeding the refrigerator outlet is a special separate circuit, it can be 15A or 20A. In an unfinished garage or basement of a housing unit, the refrigerator must have a differential circuit.
Most electrical codes (at least IRC) require that any device with a motor, such as B. a refrigerator or freezer, be connected to a dedicated 20 amp line. This means that ONLY the socket is on a circuit. Basically, but as long as the socket is NOT on a GFCI, you should be fine.
Devices that use enough energy to run their cycle include ovens, ovens, dryers, washing machines, dishwashers, and whirlpools. Some home renovations, stoves, microwaves, refrigerators, freezers, and garbage cans also use enough watts to use separate circuits.
Total load exceeds 1800 watts for a 15 amp circuit. (120 volts x 15 amps = 1800 watts.) Find the circuit rating in small numbers on the switch or fuse to find out how many outlets you can have on a 15 amp circuit. For a 20 amp circuit, the load limit is 2400 watts.
Each of these devices will function properly on the same 20 amp circuit when used in sequence. In this case, it may be better to put the dishwasher or refrigerator on a separate circuit to avoid the inconvenience of resetting the switch repeatedly.
If you need more space to store all your cold and frozen products, double check the capacity and circuit codes before plugging two refrigerators into one outlet. If you can’t help it, you can use a split cable connection to power devices on different circuits.
Lock in current requirements and change size. GE and Hotpoint Enclosures: Requires a single, properly grounded 120 volt board with a 3 pin grounded enclosure protected by a 15 or 20 amp circuit breaker or time delay fuse.
It appears that a typical 1000 watt microwave oven uses around 1700 watts. Divided by 120 (volts), that’s 14 amps. For such a microwave oven, you need to install at least a 20 amp circuit. Even if nothing else is on the track.
A freezer is considered a permanent device, so it must be on its own dedicated circuit. Dedicated circuits eliminate the possibility of overloads and power problems by running another device on the same circuit at the same time.
Refrigerator starting current
Microwave ovens use 650 to 1,200 watts of power, which corresponds to 5.4-10 amperes of electricity at 120 volts of alternating current.
