toaster, 900 W — 3.91 A on a 230 V / 16 A circuit

900 W divided by 230 V is 3.91 A. This circuit allows 12.8 A continuously, so 3 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
