Might request a single phase unit unless there is a lot of horsepower going on(10 hp. plus size motors) I would assume the purchasing agent is aware of the options. Farm Irrigation around here use a rotary converter when 3 ph. is not available. Ma and Pop (Small 1 0wner no empoyee business) make their own..
With that much electric horsepower, that fancy electric snow blower might just have some built in heaters to keep it from icing.Nowadays a VFD.....Variable Frequency Device takes care of voltage and phase. And adds a speed control.
More likely: It might very well be cheaper to power such a device with higher voltage. While the controls are a lot more expensive, you get way more power out of a smaller, lighter motor. Service wires don't need to be as heavy gauge, either.
Ambull can tell us all about that stuff; he's got some high powered certifications that tell us not to argue with him about electricity.
