How Many Amps Does a Table Saw Use?

Table Saw draws about 15 amps at 120 volts (1,800 watts running) and briefly spikes to around 38 amps at startup. At 15 A, a table saw is too much for a shared 15 A circuit under the 80% rule; it belongs on a 20 A circuit, ideally with little else running on it.

Voltage

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.

Same 1,800 W load: the current halves when the voltage doubles. Table Saw is typically a 120 V appliance in US homes.

The startup surge lasts a fraction of a second; it matters for generator sizing and breaker trip curves, not for your electric bill.

Breaker and circuit for a table saw

At 15 A, a table saw is too much for a shared 15 A circuit under the 80% rule; it belongs on a 20 A circuit, ideally with little else running on it. For a dedicated circuit, guidance is a 20 A breaker with 12 AWG copper (75°C terminations).

Worth knowing: Jobsite and contractor saws run on 120 V; 3+ HP cabinet saws require 240 V.

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.

Measure what a table saw actually draws

The figures above are typical ratings. A plug-in power meter between the outlet and the cord shows the real amps and watts with nothing opened up. A clamp meter reads one conductor at a time, so it is the tool for hardwired and 240 V circuits; clamped around a whole cord it reads close to zero.

Frequently asked questions

Table Saw typically draws about 15 amps at 120 volts, based on a typical rating of 1,800 watts (amps = watts ÷ volts). Because it has a motor or compressor, it briefly pulls around 38 amps at startup. Check the nameplate on your specific unit: ratings vary by model.
