I think you've got your units mixed up. 100A @ 120V = 12kW. Assuming the newer homes are 200A, that would be 24kW. 166kW seems ... unreasonable, especially over

- bombcar 4y agoAh I found 200 amps at 220 threephase which is still a bit more than most houses.
- quickthrowman 4y agoYour math was still off, 200 amps at 220v three-phase is ~76.2 kW. 200*220*sqrt(3)=76210 watts
- ars 4y agoUS homes are measured at 240 volts. 100 amp would be on each of the 120v legs. High power US home is 200 amp times 240 volts. More typical homes are 100 amp or 150 amp.
- kennend3 4y agoAs the other person posted, you are mistaken. Houses in north America are fed with two 120V "legs" and so the 100A is actually at 240V.
