# How to Determine What Size of Breaker to Use for Stove
Fitting the wrong breaker to your stove can be time consuming and expensive. Amperage that is too low will result in your circuit tripping frequently. This will mean you'll be spending a lot more time than you'd probably like resetting your breaker. If the amperage of your breaker is too high, you could cause permanent damage to your stove.

1
Look for the data plate on your stove. On it, you should find a section labeled FLA or LRA that will express your unit's maximum electrical capacity in either watts or kilowatts.
-
2
Determine the voltage of your circuit. This should be printed on your circuit-box cover. It's usually either 120 or 240 in the United States.
-
3
Use a calculator to multiply the capacity of your stove by 1,000 if it's expressed as kilowatts on your data plate. Then, divide the wattage of your unit by the voltage of your circuit.
-
4
Multiply the figure resulting from Step 2 by 1.25 to arrive at the amperage of the breaker you'll need for your stove. The National Electrical Code requires a circuit ampacity of 125 percent of full-load current.
