Generator Size for Three RV's
Hello, We have a spot on our farm that we would like to setup for three campers. We are wondering if we could buy one generator to power all three. One is a 50 amp with two A/C's Two with 30 a...

No, the computations are pretty simple. 50+30+30=110 amps. At 120 volts, that would be 120 x 110
= 13200 watts, so yes, a 15,000 watt generator would cover you.
I agree with the earlier posts that the 50 amp rig is 2 legs of 50 amps each, so the math is
(50+50) + 30 + 30=160amps = 19,200 watts.
You can get a generator smaller than 20,000 watts continuous duty, but remember that you won't be able to run all 3 RVs at full capacity at once. Few 50 amp RVs run at full capacity, but many 30 amp RVs do, or nearly so.
I always thought the 50 amp service was two 30 amp legs and two grounds, not two 50 amp legs. I've lost my mind and still trying to find it.
