You can't add multiple 20a 220v circuits together. Do this instead: Buy a breaker box with a 30a 220v breaker from Home depot. Install a 14-50 plug on one end, and your 30a receptacle on the other. This way you can use the 50 amp plug but still have overcurrent protection (effectively the same as a 30a circuit). If your charger already has a 30a breaker then you can just make an adaptor cord for the 14-50 outlet. Let me know if you want help building something.

>Hello Gary I did not explain that well. The place I am going to has existing 220 plugs in the hotel rooms for air conditioners. They are 20 amps circuits. If I plug into two rooms and run them into one I would still have 220 but at 40 amps. I could wire the plugs the same so they would not run power from different legs together. This would work as long as they wired all the rooms the same. I am sure the place does not want me to start taking their wall plugs out of the wall or pulling their breaker box panel off.  Do I just assume they wired all the plugs the same or should I make up a little circuit breaker box with two 20 amp plugs in and one 40 amp plug out? If it flip the breaker then I could just switch the wires on one 20 amp 220 air conditioner wall plug. ThanksDon   In a message dated 6/18/2006 10:23:48 PM Pacific Daylight Time, gary at whitecape.org writes:Don,
