> Thanks for the EU detail! Are you saying the typical house in the EU has three phase power delivered to it? All three phases?
Yes! And many electrical devices rely on it, though sometimes fallback to regular 230V single-phase at 32A is possible, e.g. for stoves.
And considering a typical stove runs at 11-15kW and a typical electric water heater between 15kW to 25kW, you'll need it as otherwise you'll need far higher amps than is reasonable.
Honestly, only due to the technology connections video did I realize that the US does not use triphase power in most homes, which was genuinely surprising.
