I was wondering why the Kill-A-Watt wattmeter that I normally leave things in the room plugged into was beeping. Turned out that having an electric kettle and a space heater both on on a circuit were enough to drive the power usage over the 1800W that a normal US household circuit can provide, and that apparently the thing beeps in that case. It let me flip off the kettle before the circuit breaker flipped, which was nice.
I think I might look into a low-wattage, vacuum-insulated (to help compensate for the fact that the heat will have to be put into the water over a longer period of time) kettle.
Oh, I’ll probably have to upgrade wiring too. Unfortunately what’s in my budget is probably single-strand 22-gauge aluminum core, if I’m lucky.
then hold on until you can do the work. electrical fires are nasty and properly sized breakers to your wiring is a major part of making it safe.
