Thermal-Magnetic Circuit Breakers are the norm here... I've never even heard of a "new" residential fusebox. I guess, with our materialism and hedonism, fuses would be very inconvenient...
Dryers and Ranges are all generally 120/240V. Water Heaters are usually straight 240V. (Not really 2 phase, but opposite poles of the same phase, if that makes sense...)
Here, back in the late 40's early 50's, the power company supplied two meter bases. One was for your lighting and power circuits for your home, the other was for just the water heater at a reduced rate. Apparently the PoCo wanted to compete with Natural Gas.
Allegheny Power owns both the electric and gas reserves here... So no competition exists anymore.

The guys in California would be more likely to have seen the exotic environ"mental" stuff!
