For the most part, an electrical circuit rated for 15 or 20 amps is more than capable of powering a slew of lights and appliances. However, there are many scenarios where a dedicated circuit that powers just one appliance is required to handle the load. Here are a few appliances that require a dedicated electrical circuit for peak performance and peace of mind.
Electric ranges are some of the most power-hungry appliances found in a home. Virtually every stove on the market will require a 240-volt circuit rated for 50 amps. There's no way to safely add another appliance to a circuit that powers an electric oven using commonly available breakers and conduit. A typical stove can draw up to 5,000 watts when pushed to its performance limit.
While a standard washing machine draws a fair amount of power, a 120-volt receptacle rated for 20 amps will do the job. If you have a gas dryer, a special 30-amp GFCI outlet can be used to power it and the washer sitting nearby. An electric dryer will require its own dedicated 240-volt circuit rated for 30 amps to ensure safe and reliable operation.
In most cases, a standard 15-amp circuit using a 14/2 NM conduit is more than capable of powering an off-the-rack dishwasher. If you plan on powering a garbage disposal unit using the same circuit, a 20-amp breaker and 12/2 wire is a must. A GFCI outlet is highly recommended and may be required depending on the local building codes in your particular jurisdiction.
Since refrigerators can use up to 15 amps on occasion, a 120-volt circuit rated for 20 amps is recommended. A compressor can draw a surprising amount of power for a short period of time when it kicks on. Adding a GFCI outlet is a good idea if it's within 6 feet of a sink or located in an unfinished basement or a garage.
A garden variety electric water heater requires a dedicated 240-volt circuit controlled by a double-pole breaker rated for 30 amps. If you have a tankless water heater, minimum wiring requirements vary based on the unit in question. Certain all-electric tankless models can draw up to 100 amps. While gas-fired, on-demand water heaters don't use as much juice, they still require a dedicated circuit.
Most common microwaves found in American kitchens need a dedicated 120-volt circuit with a 20-amp breaker for safe operation. Many microwaves produce as much as 1,500 watts when running at peak power. Consequently, a 12/2 NM conduit is a must. Depending on where the microwave is located, a GFCI outlet may be required. For instance, a microwave mounted in a cabinet shouldn't require GFCI protection.
For all but the smallest of baseboard heaters, a dedicated circuit is a smart choice that will save you a ton of headache and worry. Baseboard heaters can run on either 120 or 240-volt circuits depending on the hardware involved. A 240-volt circuit will result in greater energy efficiency. Due to the many variables involved, only licensed electricians should install dedicated baseboard heater circuits.
