I want to add a 30a RV plug on an outside wall so I can plug in my RV. Right on the other side of the wall is a 30a Dryer (220) plug that I don't use because I have a gas dryer. It seems the logical thing to do would be to come off this box.
The dryer plug is an older three wire type with a Black, Red, and White wire. There is no ground to the plug. Or, is the white the ground on this type of plug, meaning the white is not neutral?
The 30a RV recepticle has three screws which I assume are for Hot, Neutral, and Ground.
With this recepticle, can I use one of the hot wires, ie, the "Black" for power, the "White" as neutral, and add a ground? Would this be safe?
Or should I take the other hot wire (Red) and connect it to neutral in the main breaker box, and use this as my neutral to the RV recepticle?
