What is the difference between 110V and 220V?

Electric PlugMost homes in the United States mainly have standard outlets that can handle 110V. For those appliances that need more power, 220V outlets are installed.

110V is typically the amount of current the wire can handle before it becomes unsafe, and the amount of voltage supplied to the outlet.

220V is, very simply put, 2 wires that combined produce twice the amount of voltage to the outlet.

Why Not Make Them All 220V?
Copper wire is expensive, so generally homes are built with mainly 110V outlets.
220V also present safety concerns. Many of us have been shocked by an electrical outlet at some point in our lives, a 220V outlet will feel like twice the shock, and twice the pain.

Why Do We need 220V outlets?
For rooms with appliances such as a washer, dryer, oven, furnace, etc, that require the extra voltage, 220V outlets are installed.
