Go look at high power standby server power systems if you don't believe me.

I've got a 4-day weekend coming up, so maybe I can test then. The math all works though.
I recommend most people get an interlock, but I'm not going to. There's not a ready way to affix one to my panel. I'll also be testing in a less incremental way, just because going all the way is in my nature. I prefer to start at the most likely point of failure and work back to success, instead of starting with success and working towards failure.
Looking at the past 48hrs, household electricity consumption peaked at 1800 watts briefly, minus 240v circuits like the oven and EVSE. Average consumption over the past week has been 540 watts.
I plan to test the half of circuits most important to me in a power outage. I do not yet own an oscilloscope, so I can't keep an eye on waveform, but I can keep tabs on voltages and current.
