One of three things will happen:
1. It is wired correctly and everything works great
2. You have it wired wrong, but not seriously, nothing work or only half the outlets work.
3. You have it wired so that 240 volts go across half of your circuits and you burn up everything plugged into half of your rv circuits!
The 50-amp plug on an RV requires a neutral, two hot leads, 180 degrees out of phase (but that isn’t really necessary if nothing is actually 240 volts), and a ground.
Neutral has to be neutral or you are in deep trouble. If you wire one of the hot input lines to neutral and the neutral input to one of the hot lines, that half of the circuit will get 120 volts and all will work properly. The other half will have one of the hot input lines as the neutral and the other hor input line as its hot line. The result is 240 volts across that “neutral” to hot connection and everything on that half of the circuits will get 240 volts, possibly blowing up your frig, microwave, TV, or anything else!
