Generally, a microwave in the USA uses 8.3 amps (approximately). The number of amps a microwave uses depends on its wattage and the voltage of the electrical system it’s connected to. In the United States, where standard household voltage is 120 volts, you can calculate the amperage using the formula:
Amps=Watts/Volts.
Common Examples
- 600-Watt Microwave:
600 watts÷120 volts=5 amps - 1,000-Watt Microwave:
1,000 watts÷120 volts=8.33 amps - 1,200-Watt Microwave:
1,200 watts÷120 volts=10 amps
Additional Considerations
- Peak Power Usage: A microwave may draw slightly more amps during startup or peak operation. Always check the specific model’s manual for exact figures.
- Dedicated Circuit: Many microwaves require a dedicated 15-amp or 20-amp circuit to prevent overloading.
Always verify the microwave’s specifications to ensure compatibility with your electrical system.
