Answer 1

Answer:

Most homes have three-wire service—two hot wires and one neutral. Electrical utilities deliver electricity through a masthead at the roof. Wires continue through the meter to the main panel. ... Both hot wires and the neutral wire make a 240-volt circuit for large appliances such as air conditioners and electric furnaces.
