There are exceedingly few homes, especially single-family homes, in the US that do not have split-phase 240V power.
208V (2 legs of 3-phase) power is almost always relegated to condos or apartments and never single-family homes. Even in that case, many 240V appliances function just fine on 208V albeit at a lower maximum power.
Even fewer still, to the level that you don't have a 'home' at that point but, but a small commercial building, have 480V power. Only commercial buildings have 480V, and they basically always will have conversions to usable residential power for using... normal stuff.

- Kirby64 1y agoRight, so if you’re getting 480V hooked up you have a small commercial building at that point. And you probably still have 240V feed for the rest of the house. Also, these days you have many more options than just getting 480V. Running a VFD off 240V to generate 3-phase is much more affordable generally for a used lathe or something. Even getting 480V connected to a house is sometimes impossible, or at very least so expensive it makes no sense.
