I know squat about electrical issues, but have found several good wiring diagrams for Rancos, so I'm good there. I have a 15A extension cord that I cut to wire it up and, unfortunately, the only wire that is identifiable by color is the ground. The other are not colored.
Does it matter which you consider common and which you consider hot (i.e. the wire going to one of the prongs always going to be the common and one side the hot?). If so, I may have no choice but to hope that the next one I cut has colored wires! I hate to waste another cord, but better that than the Ranco or me!
Thanks for any input.
