iron, 1500 W — 12.5 A on a 120 V / 15 A circuit
1500 W divided by 120 V is 12.5 A. This circuit allows 12 A continuously, so 0 of them can run together.

Continuous loads get eight tenths
A breaker does not trip the instant you reach its rating — it holds for a long while first, and the wire warms up in the meantime. So a load running more than three hours is planned to eight tenths of the breaker. On a 16 A breaker that is 12.8 A.

How to read this
- Current is the power draw divided by the voltage — a different country gives a different answer.
- The number that fits at once is eight tenths of the breaker divided by that current.
- A power strip stops at 15 A. A bigger breaker does not help; the strip is the ceiling.
- The wire gauge is taken straight from the wire pages.
Frequently asked questions
Q. How many amps does a iron draw?
1500 W over 120 V is 12.5 A.
Q. How many fit on this circuit?
0. Eight tenths of the 15 A breaker is 12 A, divided by 12.5 A.
Q. Is a power strip fine?
Yes — it stays within the 15 A a common strip holds.
Q. What wire does it need?
AWG 14 carries this current comfortably. Two hours a day comes to 90 kWh a month.
