Wow. A 400 amp service?
Reports the George Washington Bridge in #NYC is now fully closed due to high winds.
Our first single family house had 100 amp service. We were always blowing fuses. Our second house had 200 amp service, built in 1993. Didn't trip the circuit breakers very often, but it happened. As well, we had gas heat and a regular air conditioner, and only one zone.
This house has 400 amp service, but a big part of that is the “electric furnace” that comes on when it gets too cold for the heat pump to heat the house anymore in the winter. I'm told that those things are electric hogs. And I have TWO heat pumps, not one, for two-zone heating and cooling.
All things considered, since I have an all-electric house, my bills aren't too bad. Pretty decent insulation, the heat pumps were pretty efficient when we built the house 10 years ago (although they're no longer considered very efficient at all), we're careful about keeping the thermostat reasonable. All in all, it doesn't cost much more, when taking into inflation, to provide the electricity we need for everything, including heating and cooling, than we spent for electric + gas 10 years ago. And that house was only about 2300 sq ft, and this one is about 3200 sq ft.
But the peak usage to turn some things on, and to keep them on for the periods of time they need to be on, is pretty outrageous.
