What uses 220V in a house?

How do I know if my electricity is 220?
If it has 220V, there will be three wires from the power line to your electrical panel, two hot and one neutral. Measuring across the two hot leads, should give you 220V.
What's the difference between 110V and 220V?
Each 110-volt circuit connects to a single bus bar and has only one hot wire, so only one circuit breaker is needed. By contrast, a 220-volt circuit connects to both bus bars, so two breakers are needed one for each bus bar and each wire that connects to that bar.Mar 3, 2019
