TV, 120 W — 1 A on a 120 V / 20 A circuit

120 W divided by 120 V is 1 A. This circuit allows 16 A continuously, so 16 of them can run together.

This circuit handles it

Fine on a power strip

Power draw: 120 W
Voltage: 120 V
Breaker: 20 A
Current that flows: 1 A
Limit for continuous use: 16 A
How many fit at once: 16
Wire it needs: AWG 24
Two hours a day, per month: 7.2 kWh

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 TV draw?

120 W over 120 V is 1 A.

Q. How many fit on this circuit?

16. Eight tenths of the 20 A breaker is 16 A, divided by 1 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 7.2 kWh a month.
