A standard dishwasher in the United States typically requires a 15-amp circuit to operate. Most household outlets in the US are rated for 15 amps, and dishwashers are designed to be compatible with these common electrical circuits.
However, it's important to note that some dishwashers may have higher power requirements, and in those cases, a 20-amp circuit might be necessary. High-end or more feature-rich dishwashers may require additional power to operate efficiently, and their specifications should be checked to determine the appropriate circuit amperage.
Before installing a dishwasher, it's essential to review the manufacturer's specifications and installation guidelines to ensure the proper electrical circuit and outlet are used. If you are unsure about the electrical requirements or the suitability of your current electrical setup, it's best to consult with a licensed electrician for advice and installation.
