NOTE the 30AMP RV connection is usually the one most likely to burn up all of your 120VAC appliances as some unknowing folks will wire these up using two HOT connections as it resembles the house 240VAC Dryer wiring connections.

This is the best illustration/explanation in this thread. clear, concise, and totally accurate!
Many times, "Hot" will be noted as "Line", as in "Line 1" and "Line 2".

Actually, no convoluted explanation needed. This explains it all, as previously noted!

Just semantics. NEMA 14-50 is 120/240 service that for some reason needs an extensive convoluted explanation. Virtually every home in the USA is wired the same but everyone gets befuddled with an explanation about how an RV works.

If the appliance was only 240v the plug would most likely be NEMA 6-50

For those reading this thread in confusion, 1. Listen to Hank. 2. Don't go re wiring anything based on some of the info presented here!

I think you're right. Some people refuse to accept that it's the supply, in this case 50 amp 240v, that determines that it's a 240v RV not how you divide up the 2 legs and use them. So I guess I'll just let it go.

Thats the MO of rvnet threads man! Too much geritol. This is like a live version of that old movie "Grumpy old men."

Circuits that are 120/240 volts are not normally referred to as having phases although the current is flowing 180 degrees apart.

You misunderstood what I was saying. I said if both hot legs were in phase, meaning supplied from the same source hot leg then no neutral canceling would take place. If the 2 hot legs are 180* out of phase then neutral canceling would take place. People keep insisting the 50 amp supply is 2 120v supplies. Technically and by code it's a 240v supply as the 2 hot legs are 180* out of phase. As i said earlier it's no different than the service coming into your house. Almost everything in your house runs off 120v, one of the 2 hot legs. It's quite possible to have no 240v loads at home.

Why people keep insisting that the RV 50 amp supply is some how different is beyond me. It's a 240v 50 amp supply. How the 2 hot legs are used to supply 120v or possibly together to supply 240v is irrelevant. Same thing occurs in your home but it's still a 240v supply.

"Possible" I suppose, particularly for those running gas appliances, but I suspect the vast majority of newer homes these days will in fact run an electric oven and electric clothes dryer, each of which requires 240 vac 2-phase power, which of course is easy since incoming power wired to the house breaker panel is exactly that.

All 50 amp feeds are two legs of 110 volts. All campers are 110 volts. No such thing as a 240 volt camper.

Since my MH accepts 240v at 50 amps and manages the two hot legs I would say it's a 240v MH. If it only used one hot leg and had a single pole main breaker as opposed to a 2 pole main breaker then it would be a 120v MH. It doesn't have to have any 240v appliances to be considered a 240v MH. It accepts and manages 240v therefore it is a 240v MH.
