 2006/3/1 [Science/Electric] UID:42041 Activity:moderate ```3/1 Say I have a circuit breaker that says 20A. How many watts can I load on it before it pops? I'm asking because every time I have a space heater (1500W) and hair dryer (1850W) on, the circuit breaker pops. \_ P = VI where P is power in watts, V is voltage in volts, I is current in amps (A). Wall socket voltage is a max of 120V in the USA and is 220V-240V in some places elsewhere. Can you figure it out now or do you need more help? \_ [80 column nazi-ism removed, helpful original 83 col text restored] So take *that* 80 col nazi! --content quality >>> 80 cols retentive ness and format advocacy. \_ P = VI where P is power in watts, V is voltage in volts, I is current in amps (A).

Rally, damn you, RALLY! \_ AS a rough estimate, and with normal US household power, you can say 100W = 1A, so you're trying to throw 33A through that 20 circuit breaker. Of course it's going to blow. \_ Isn't this high school physics?```

This would be for use with electronics that accept 100V-240V. While the power strip is intended for use at 120V, it's just wires, right? (Also, this power strip has no power LED or similar.) If anything, ... ```
