The reason one side is hot and the other neutral is that it's a
convenient way to get 220 V. You have two hot sides, each at 110 V to
a common neutral, but at 220 V to each other. That's why you have
three conductors coming into your house. That way, things like
electric stoves, clothes dryers, heavy machinery, etc. can use the
higher voltage and lower currents.
