How Many Amps Does a Toaster Use?

The running amps a toaster draws, the watts-to-amps math behind it, and the branch circuit it belongs on.

Quick answer: A toaster uses about 9.2 amps at 120V (roughly 1,100 watts). It belongs on a shared 15A or 20A / 120V circuit. Amps = watts ÷ volts; the nameplate governs.

A toaster or toaster oven draws about 7-12.5 amps (850-1,500 watts) while heating, on a kitchen small-appliance 20A circuit. A large toaster oven at 1,500 watts is 12.5 amps by itself, so do not run it at the same time as a microwave or kettle on the same circuit. Amps = watts / volts; keep the continuous load under 80% of the breaker. The nameplate lists the exact draw and always governs over a typical value.

Frequently Asked Questions

How many amps does a toaster use?

A toaster uses about 9.2 running amps at 120 volts (roughly 1,100 watts). To get your unit's exact draw, divide the nameplate watts by 120: amps = watts / volts. A toaster or toaster oven draws about 7-12.5 amps (850-1,500 watts) while heating, on a kitchen small-appliance 20A circuit. A large toaster oven at 1,500 watts is 12.5 amps by itself, so do not run it at the same time as a microwave or kettle on the same circuit.

What size breaker for a toaster?

A toaster does not need its own breaker; at 9.2 amps it shares a standard 15A or 20A / 120V circuit (NEC 210.52(B)). Just avoid running it at the same moment as another heavy load on the same circuit. Keep the total continuous load under 80% of the breaker.

How do I calculate the amps a toaster draws?

Divide the wattage on the nameplate by the voltage: amps = watts / volts. A toaster at about 1,100 watts on 120V works out to 1,100 / 120 = 9.2 amps. The nameplate always governs over a typical value.

How many amps does a toaster oven use?

Same answer: toaster oven is another name for a toaster. It draws about 9.2 amps at 120V on a shared 15A or 20A circuit. A toaster or toaster oven draws about 7-12.5 amps (850-1,500 watts) while heating, on a kitchen small-appliance 20A circuit. A large toaster oven at 1,500 watts is 12.5 amps by itself, so do not run it at the same time as a microwave or kettle on the same circuit.
