I know this isn't quite what you mean when you say electrical engineering, but, how many amps is a standard three-pronged edison plug rated at? Also, what is common house wiring rated at? I believe that a three-pronged plug is rated at 15 amps and that logically the wiring should be able to carry at least that. By my calculations then in the US with good ol' 120-volts you should be able to carry 1800 watts on a wall outlet. I'm just a layman at electricity and I just wanted to be sure. As much as some people dream about it I don't want to burn down my school.
