wiring a 20A-250v 3-wiring grounding
I have a subpanel directly under my main breaker on the meter pole. This subpanel was used for a 8 x 12 shed. that was set up with a small a/c, light, and about 6 outlets. the wire running from the subpanel to the breaker box inside the shed was a 10/3 and has four wires. I no longer have the shed. I want to run this to a 20A-250v outlet for an A/C -heater window unit. But the outlet only has three screws.
I was told to combine the red and black together and use on one screw. then the white to other top screw and ground to ground. Will this work?
