vacuum cleaner, 1700 W — 17 A on a 100 V / 15 A circuit

1700 W divided by 100 V is 17 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 vacuum cleaner draw?

1700 W over 100 V is 17 A.

Q. How many fit on this circuit?

0. Eight tenths of the 15 A breaker is 12 A, divided by 17 A.

Q. Is a power strip fine?

No. It passes 15 A, so plug it straight into the wall.

Q. What wire does it need?

AWG 12 carries this current comfortably. Two hours a day comes to 102 kWh a month.
