Generator voltage

So I have a 120v 2 hots and a neutral 10 kw powertech. At the panel I have 2 hot legs a neutral and ground. With that said if I get 120 off of each leg would I not have 240? Case in point a 220v dryer.

No, not necessarily. My generator is wired so that both hot legs are in phase. Each leg is hot, but if you put a volt meter across the two hot legs, it reads zero volts, not 220. If you are plugged in to 50 amp shore power, however, and you put a volt meter across the two hot legs, it does read 220. I don't know why they configured the generator that way. For one thing, in my coach nothing uses 220 volts.

A member of the forum posted years ago about wanting to be able to use his generator to provide 220 volt backup power to his house. If I remember correctly, he had Power Tech change the wiring so his generator would provide 220 volts. He said it wasn't a difficult thing for the technician to do. I like that idea myself. It would be nice in an emergency to be able to supply the house, including the electric range.

I you have the right generator; the one with the wires going from the generator, to the box mounted on top of the generator, labeled as "T" xx wires, that connect to the goodies inside of the box, you can get 240v across the two legs, and 110v from either leg to neutral.
The wiring from the 240v gen output to the transfer switch may need to be rewired.
Additional research is needed....
