laptop, 65 W — 0.28 A on a 230 V / 16 A circuit
65 W divided by 230 V is 0.28 A. This circuit allows 12.8 A continuously, so 45 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 laptop draw?
65 W over 230 V is 0.28 A.
Q. How many fit on this circuit?
45. Eight tenths of the 16 A breaker is 12.8 A, divided by 0.28 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 24 carries this current comfortably. Two hours a day comes to 3.9 kWh a month.
