In terms of power, the equation goes like this: 30-amps x 120 volts = 3600 watts. That is how much power you can use at any given time. Compare that to the 50-amp equation- 50 amps x 240 volts = 12,000 watts. Obviously, you can run more appliances with the latter system. You will also pay more for that privilege.
