17 Amps to Watts
17 A = 2,040 W
17 amps at 120 volts is 2,040 watts (4,080 W at 240 V).
Step by step
- Use the formula watts = amps × volts (P = I × V).
- At 120 V: 17 × 120 = 2,040 W.
- At 240 V: 17 × 240 = 4,080 W.

How it works
Power in watts equals current in amps multiplied by voltage: P = I × V. On a standard US 120 V outlet each amp delivers 120 watts; on a 240 V circuit each amp delivers 240 watts. For breakers, plan continuous loads at no more than 80% of the rating — that is why a 15 A circuit is usually limited to about 1,440 W of continuous load.
