TIL my microwave uses 100% of the 15A a North American plug can provide.
The voltage on that circuit doesn't sag appreciably from 120V under load, so it's using 200W more than the nameplate says it should, 1600W.
I'm a bit surprised that Black & Decker used such close margins; my kettle draws a more reasonable 13A.
It's no wonder they changed the building codes here to require 20A outlets in kitchens... 😂
@pete not sure what manifacturers advertise as power output, but A/C *effective* power output is 0.5*I^2*R = 0.5*I*V (because cosine squared averages to 0.5). However, it could well be they specify maximum power output, just I*V for marketing purposes
