So each of the two legs of your 50-amp outlet calculates as 120 volts x 50 amperes = 6,000 watts. And since you have two identical 50-amp legs, you can find the total wattage by simple addition of the two legs. Thus 6,000 watts + 6,000 watts = 12,000 watts total power from a 50-amp, 120/240-volt pedestal outlet.
