As it gets closer to your house it goes to a sub station where the voltage is lowered and then sent on its way. It finally arrives in your neighborhood and is sent to a transformer where the voltage is lowered to 220 volts. This is what comes into your house and goes to the circuit breaker box. The next section describes a bit of technical mumbo jumbo about sine waves and phase relationships.
This is because so many devices need to convert from the high AC voltage received from the mains power supply to a more lower DC voltage. How this is achieved is through a step-down transformer. The step-down transformer may convert 120VAC from mains to 12V by having a primary to secondary coil with a 10:1 ratio. The voltage output by the transformer is 12VAC.
