A dishwasher typically uses a standard electrical outlet. In most regions, dishwashers are designed to be connected to a 120-volt, 15-amp electrical circuit. The outlet for a dishwasher is commonly a three-pronged outlet, known as a NEMA 5-15R receptacle, which is compatible with the dishwasher's power cord. However, it's important to note that electrical requirements can vary depending on the specific model and regional electrical standards. Always refer to the manufacturer's instructions and local electrical codes when installing or connecting a dishwasher.
