# How Many Amps Does an Electric Oven Use?

There is no single amperage for every electric oven. A countertop oven, a built-in wall oven and an electric range can have very different electrical requirements. Use the rating plate and installation instructions for the exact model and country version.

The circuit-breaker rating is not the amount of current the oven draws continuously. Do not assume an existing circuit is suitable simply because its breaker number falls within a general range.

## What Do Volts, Amps and Watts Mean?

Volts describe the electrical potential difference, amps measure current and watts measure power. [Kilowatt-hours measure energy used over time](https://www.eia.gov/energyexplained/electricity/measuring-electricity.php). These are related quantities, but they are not interchangeable.

For a simple resistive load, power in watts is voltage multiplied by current. For example, 2,500 watts divided by 240 volts is about 10.4 amps, while 2,500 watts divided by 120 volts is about 20.8 amps. These are arithmetic examples, not specifications for an oven.

For an appliance with motors or electronic components, the relationship can also involve power factor. Use the manufacturer’s stated input current and installation requirements rather than relying on a simplified calculation to design the circuit.

## Where Should You Look for the Rating?

Find the model number and rating plate using the manual’s directions. Do not pull out a hardwired oven or remove electrical covers just to find a label. The manufacturer’s installation document should identify the required supply, grounding and circuit protection.

Make sure the document matches the exact model and voltage version. The age of the house, the shape of an outlet or a cable’s apparent thickness cannot establish its capacity.

## What About Microwave Wattage?

A microwave’s advertised cooking output is different from the electrical input it takes from the supply. Do not divide the cooking-wattage figure by the supply voltage and treat that as its installation current. Use the input rating and the microwave’s electrical instructions.

## Who Should Check the Circuit?

Have a [qualified electrician assess the existing wiring, connection, protection and local requirements](https://www.usfa.fema.gov/prevention/home-fires/prevent-fires/appliance-and-electrical/index.html) when installing or replacing an oven. A higher-rated breaker is not a safe way to upgrade undersized wiring.

If a breaker repeatedly trips, stop using the appliance and have the cause investigated rather than repeatedly resetting it or fitting a larger breaker. Preserve grounding and use only the connection arrangement the manufacturer permits.
