I tend to think of the 50 amp RV power as being 100 amp equivalent. You can get 50 amps of 120 vac thru hot leg 1 and/or 50 amps of 120 vac thru hot leg 2. That gives the equivalent of 100 amps of 120 vac (12,000 watts). Or you could even get 50 amps of 240 vac (also 12,000 watts). But there is never more than 50 amps of current ever passing thru any given wire. The center neutral really confuses things unless you really fully understand current flow with two hot legs out of phase.
