Hi, I recently moved to NJ. My almost new dryer has a 4 pronged cord/plug, while the wall socket is 3 pronged. Could I convert the socket to a 4 pronged? I see a wire coming to the socket with 4 wires - red, black, and white, and a copper naked wire currently connected to the body of the socket bin. I also purchased a 4 hole socket from hardware store.
