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?
Yes, if a single 120 volt service is wired to both L1 and L2, the neutral carries the total load from both hot legs. Assuming a standard 50 amp single breaker though, the total load cannot exceed 50 amps.
Standard residential/RV 120/240 volt service is not "2 phase", it's a single "split-phase" service.
