Electricity? Never touch the stuff
I'm hiring an electrician to run a 50 amp line at my daughter's house for my RV. I only need 50amps because I have two A/C units. It's a 30' toy hauler. No W/D hookups. Everything is 110 (I believe). ...

Two questions,
1. I've heard of some wiring the same 120V phase to both sides. Wouldn't this drive twice as much current through neutral line?
2. Other than the problem of hooking to a single phase circuit, why wouldn't the AC units be 2 phase? Wouldn't that be much more energy efficient?
What is being discussed(?) here is called split phase. The return path on the neutral line carries an inverted sine wave from L1 & L2. When L1 & L2 carry a balanced load, there is no current flow on the neutral path.
Maybe you can follow this.

RLS7201 is 100% correct. The neutral only carries the unbalanced load between the two line.
