Generally speaking in a residential home, an electrical circuit rated for 15 or 20 amps is adequate for powering a many lights and even several appliances. However, there are some possible situations when a dedicated circuit that supports just one appliance is needed. Here is a quick guide to each major appliance, and how to power them for the best performance and safety.
Dishwashers: typically, a standard 15-amp circuit using a 14/2 NM conduit can readily power an off-the-rack dishwasher. However, if you plan on adding garbage disposal unit to the circuit, you must use a 20-amp breaker and 12/2 wire. A GFCI outlet is highly recommended – and in fact, may be required by law depending on local building codes.
Microwaves: Typical microwaves need a dedicated 120-volt circuit with a 20-amp breaker to safely operate. Microwaves put out as much as 1,500 watts, so a 12/2 NM conduit is the best choice. Depending on where the microwave is located, a GFCI outlet may be required. For instance, if sitting on a countertop near a sink, water intrusion is a possibility and a GCFI should be utilized.
Refrigerators: Refrigerators are known to use as much as 15 amps, as a compressor can use quick a bit of power. Therefore, most residential electricians will recommend a 120-volt circuit rated for 20 amps. Adding a GFCI outlet is prudent if the refrigerator is within 6 feet of a sink, or if it is sitting in an unfished area such as a garage.
Stoves: Perhaps it is appropriate that our electric ranges are always hungry for power. In fact, nearly every late model stove will necessitate a 240-volt circuit rated for 50 amps. There’s no real safe option to add another appliance to the circuit that powers an electric oven – at least not utilizing breakers and conduits typically available to homeowners. When used frequently, your stove can draw 5,000 watts all on its own. A dedicated circuit is likely the best way to power your stove.
Laundry Machines: A 120-volt receptacle rated for 20 amps should be acceptable to run most washing machines. If the dryer is powered by gas, a specialized 30-amp GFCI outlet can be utilized both for the direr and washer. An electric dryer needs its own dedicated 240-volt circuit rated for 30 amps, other wise you are risking safety and could damage your machine.
Water Heaters: A run-of-the-mill electric water heater needs a dedicated circuit (240 volt) controlled by a double-pole 30 amp breaker. While gas-powered on-demand water heaters don’t use as much power, they still should be on a dedicated circuit.
