2,000 Watts to Amps
2,000 W is 8.696 A at 230 V and 16.67 A at 120 V (single-phase, power factor 1). Table for DC and three-phase, power factor 0.8, and the formula.
Formula
Worked example
- I = 2,000 / (230 × 1) = 8.696 A
- With a power factor of 0.9: I = 2,000 / (230 × 0.9) = 9.662 A
On other supplies
| Supply | Voltage | Current at pf 1 | Current at pf 0.8 |
|---|---|---|---|
| DC | 12 V | 166.7 A | not used |
| DC | 24 V | 83.33 A | not used |
| DC | 48 V | 41.67 A | not used |
| Single-phase | 120 V | 16.67 A | 20.83 A |
| Single-phase | 230 V | 8.696 A | 10.87 A |
| Single-phase | 240 V | 8.333 A | 10.42 A |
| Three-phase | 208 V | 5.551 A | 6.939 A |
| Three-phase | 400 V | 2.887 A | 3.608 A |
| Three-phase | 415 V | 2.782 A | 3.478 A |
| Three-phase | 480 V | 2.406 A | 3.007 A |
Three-phase rows use the line-to-line voltage. DC ignores the power factor.
What 2,000 W looks like
2,000 W is about the load of an electric kettle or a large hair dryer.
This is an estimate of the load current only. Choosing a cable or a breaker also needs the installation method, the ambient temperature, the voltage drop and the rules you work to.
Frequently asked questions
How many amps is 2,000 watts?
2,000 W is 8.696 A on a 230 V single-phase supply and 16.67 A on 120 V, both with a power factor of 1. The current depends on the voltage, so it is a different answer on every supply.
What if the power factor is not 1?
The current rises. At 230 V and a power factor of 0.9, 2,000 W draws 9.662 A. Heaters and filament lamps are close to 1, while motors and many power supplies are lower.
What about a three-phase supply?
2,000 W on 400 V three-phase at a power factor of 0.8 is 3.608 A. The line voltage is used with the factor √3 (about 1.732).
