120/240 volts at 60 cycles per second ac.
It is supplied as a single phase service, split 120V-0-120V.
One hot leg is 120 volts, a second hot leg 120 volts but running at 180 degrees out of phase from the first leg, and a neutral.
Every 120 volt outlet in your home carries one leg of 120 volts plus the neutral.
If the outlet has a ground, this is for safety in case there is a fault like a short of a hot leg to the internal frame or the outer casing of the appliance, which should always be connected to the ground. If such a fault occurs, the ground wire takes a very high current which causes the circuit breaker to trip or a fuse to blow.
An appliance such as a clothes dryer in your home, that uses 240 volts, is using both hot legs. Because they are 180 degrees out of phase from each other, the combined voltage is 240 volts.
