I bought a new drier with the "inverted V" 3-wire power plug. The drier outlet I have is like an overgrown version of a 110 grounded outlet, with 2 vertical 110 prongs and a ground socket. I bought a V-socket to accommodate the new drier plug, but when I shut off the breaker and opened up the old socket, I found red and black hot wires, and apparently a bare AND a white ground wire. My question: Do I need to hook BOTH the white and bare wires to the ground terminal, or just ignore the white wire altogether?
