Users must wire their Powder units, the way their country / state or electrical contractors choose to wire, to ensure safety codes are met. 220v/20A breaker is usually adequate for the Slim Shaker, but they might require a 30A, and this choice, and their method ( wire directly into grid), or outlet style will determine the plug they will need to use. It's up to the user to make that choice.
Note that this is a 220V unit.
