How Many Amps Does a Coffee Maker Use?

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

Quick answer: A coffee maker uses about 10 amps at 120V (roughly 1,200 watts). It belongs on a shared 15A or 20A / 120V circuit. Amps = watts ÷ volts; the nameplate governs.

A coffee maker or Keurig pulls about 8-12.5 amps (1000-1500 watts) while the heating element is on, then almost nothing between brews. It shares a kitchen small-appliance 20A circuit but should not run at the same moment as another heating appliance (toaster, kettle) on the same circuit, which is what trips the breaker. 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 coffee maker use?

A coffee maker uses about 10 running amps at 120 volts (roughly 1,200 watts). To get your unit's exact draw, divide the nameplate watts by 120: amps = watts / volts. A coffee maker or Keurig pulls about 8-12.5 amps (1000-1500 watts) while the heating element is on, then almost nothing between brews. It shares a kitchen small-appliance 20A circuit but should not run at the same moment as another heating appliance (toaster, kettle) on the same circuit, which is what trips the breaker.

What size breaker for a coffee maker?

A coffee maker does not need its own breaker; at 10 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 coffee maker draws?

Divide the wattage on the nameplate by the voltage: amps = watts / volts. A coffee maker at about 1,200 watts on 120V works out to 1,200 / 120 = 10 amps. The nameplate always governs over a typical value.

How many amps does a keurig use?

Same answer: keurig is another name for a coffee maker. It draws about 10 amps at 120V on a shared 15A or 20A circuit. A coffee maker or Keurig pulls about 8-12.5 amps (1000-1500 watts) while the heating element is on, then almost nothing between brews. It shares a kitchen small-appliance 20A circuit but should not run at the same moment as another heating appliance (toaster, kettle) on the same circuit, which is what trips the breaker.
