Right, 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.

Right, 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.
