The usual wall circuit is 15 Amperes, times 120 volts peak is 1800 watts.
746 watts in a horsepower, so how do you get 4.5 HP out of a wall socket?

It's probably more like 15 or 20 amps and that is 115 to 120 volts
RMS, not peak. Peak is 1.414, or roughly 162 volts. On single phase
they current and voltage should be close enough for all practical
purposes to call them in phase. (except during starting)

If it were DC, you'd be correct. AC has more or less sinusoidal voltage

So, using RMS at 115 volts he's still close.

and current, not necessarily peaking at the same time, and a whole bunch
of other stuff I used to know about.
