I'll throw in another point. It does not have to be 240 volts between the two hot legs. We have been in a number of RV parks, one just a couple days ago, that has 120 volts on each hot leg, but a meter across the two hot legs measures 208 volts. All this as a reminder to forget talking about 240 volts or 208 volts, as this does not matter with most RV's, only 120 volts. Also, residential watt hour meters do measure the watts on both legs. The coils on both legs inside the meter are wound around the same core in the meter and regardless of how much current there is on each leg, they are added to the watt hour reading on the meter, so, if, as was mentioned, there was 6,000 watts on each leg, the watt reading will be 12,000 watts, not 6,000 watts, but actually measured in watt hours.
