Terms of the Trade: What Is a 110 Line?

Lead Image

The standard voltage for a typical household circuit is 110 volts, often called a "110 line." This will support most appliances and lighting used in kitchens and throughout the house. These days, it's a bit of a misnomer, since the standard voltage has been 120 for many years in most of the world.

220 line (actually 240) is a higher voltage used for large appliances that need a higher amperage, such as an electric clothes dryer.
