How Many Amps Does a Sewing Machine Use?
Sewing Machine draws about 0.8 amps at 120 volts (100 watts running). At 0.8 A, a sewing machine fits comfortably on a standard 15 A or 20 A household circuit.
Amps = watts ÷ volts. Enter the wattage from your appliance's nameplate or label for an exact figure.

Breaker figure is guidance for a simple resistive load — confirm against the nameplate and a licensed electrician.
Sewing Machine amperage at 120 V and 240 V
Same 100 W load — the current halves when the voltage doubles. Sewing Machine is typically a 120 V appliance in US homes.
| Draw | Watts | Amps at 120 V | Amps at 240 V |
|---|---|---|---|
| Running | 100 W | 0.8 A | 0.4 A |
Breaker and circuit for a sewing machine
At 0.8 A, a sewing machine fits comfortably on a standard 15 A or 20 A household circuit. For a dedicated circuit, guidance is a 15 A breaker with 14 AWG copper (75°C terminations).
Guidance only — actual circuit sizing depends on your unit's nameplate, wire run length, and local code. Confirm with a licensed electrician. See the wire & breaker size chart for the full NEC ampacity table.
