Most everyday appliances only need enough electricity for a 120 volt outlet. Microwaves, refrigerators, and dishwashers are examples of examples that will function perfectly fine on 120 volt outlets. You will recognize these outlets anywhere in your home.
Dishwasher – A large range of dishwashers use the standard current of 110 volts. It is best to use an outlet that has a Ground Fault Interrupter or GFI. This will provide an extra precaution if the outlet gets wet. A GFI is designed to trip or disconnect power to prevent electrocution.
All residential dishwashers operate on the nominal voltage of 120 volts but not the same current. Current is measured in amps, and these amps are the size of the breaker you may require. To figure the amps, read the label of your specific appliance to find the dishwasher's amp draw and match the breaker accordingly.
Since 15A outlets have been the standard for so long, almost all small home appliances are designed to work with a 15A outlet. Some high-end dishwashers do require a 20A circuit, but most mainstream units are still 15A.
Dishwasher Circuit
When installing a dishwasher, the circuit should be a dedicated 120/125-volt, 15-amp circuit. This 15-amp circuit is fed with a 14/2 NM wire with a ground. You may also elect to feed the dishwasher with a 20-amp circuit using 12/2 NM wire with a ground.
Dishwashers are hardwired. They consume a relatively high amount of power, so it is not advised to use the same method to connect your other household appliances.

With heat doubled than that the 240 v appliance can carry, the appliance will overheat, melt, or explode, or burn.
You can also look into the gang box of your existing thermostat. If you have black and white wires you likely have 120V. If you have black and red wires you likely have 240V.
The dishwasher needs a single-pole breaker that has at least 15amps. If you operate the dishwasher on the same circuit breaker as the garbage disposal, you need to use a 20 Amp breaker.
Dishwashers can use between 1200-2400 watts1, although the average dishwasher uses only about 1800 watts per cycle (roughly the energy used to power a hairdryer for ten minutes). The electricity used by a dishwasher is usually needed only on the control electronics and the pump.
A dishwasher should be on at least a 15 amp circuit. 15 amps is enough for most dishwashers on their own dedicated circuit. A dedicated circuit is a plug used for just one appliance, with nothing else plugged into it. Some dishwashers draw more power than most, and may need to be placed on a 20-circuit breaker.
Features. The modern 120-volt power outlet has three holes: two parallel rectangular slots—one connected to the "live" wire and one connected to the neutral wire—and a round hole for the ground wire. Most outlets are "duplex" receptacles, with two places to plug in electrical devices.
The most common electrical outlet in any home is a 110 volt. Sometimes you may hear 110 volt plugs referred to as 120 volt.
Appliances like large air compressors, welding machines, water heater, dryer, and oven require a 240-volt outlet to perform efficiently. They can also run on a 120-volt outlet, but it will reduce its efficiency.
In most of the world, household outlet voltage is 220 volts. In the United States and neighboring countries, however, household outlets run at 110 or 120 volts. This can pose a serious problem for travelers. Connecting a 220 volt appliance to a 110 volt outlet can damage or destroy the appliance.
If you see something like “INPUT AC 120/240 V 50—60 Hz 1300 W,” then your device is dual-voltage, and you can safely use it for voltages anywhere between 120 V and 240 V.
So, what's the difference between the two types of outlets? A standard 120V outlet contains a 120 volt wire and a neutral wire, and preferably a grounding wire. A 240V outlet has two 120 volt wires and a neutral wire.
The differences between 110 and 120v are too small to matter. If your power supply has a rating of 120v, it actually has a range of 110 to 125v. Any appliance whose rating falls within that range can work on both 110v and 120v outlets.
As 110v and 120v are almost the same, there is no specific difference on which device is for which outlet. Electrical appliances are designed to work in a range of voltages. So, considering that, if a device works in a 110v outlet, it should work in a 120v outlet as well.
No, not all dishwashers are hardwired. Instead, you can purchase dishwashers that come prepared with an electrical cord and a three-prong plug. These units will easily connect to a regular wall socket that you'd have in your household kitchen.
According to the electrical code, the dishwasher should be on its own circuit. The dedicated dishwasher circuit can't supply any other appliances, lights, fixtures, or outlets. In addition, the circuit that is servicing the dishwasher also needs to have a circuit breaker with at least 15-amps.
In the time it takes to run to the breaker box to turn off the breaker, the dishwasher could deposit an inch or two of water on the floor. A hard-wired connection, on the other hand, avoids the need for an extra receptacle under the sink, where there may not be room for one.
The common 15 amp, 120 volt household outlet (also called a receptacle) is used throughout North America. Lamps, vacuum cleaners, refrigerators, etc. plug into it. The outlet has two vertical slots; the U-shaped hole is for the green safety grounding wire.
