      I just moved into a new abode and brought my dryer. I have a three pronged cord and the wall has a three pronged outlet. Looks good except there is a copper wire (ground?) sticking out of the side of a metal box containing the outlet. Should I hook up that copper wire to my dryer ground?

      In mobile homes, connect the fourth green ground wire to the dryer frame, esp. in states like Alabama during hot dry weather where dry clay soil does not make a good electrical conductor to the house ground stake which is driven into the earth.
      Otherwise, during dry spells, I have measured up to 90 volts between the electrical ground and the metal housing of househole appliances.
      Hot wires- Phase A (black) is 120VAC to common (white). Phase B is 120VAC to common (white).
      Get 240 across Phase A and Phase B.
      Common (white) – Connects directly to the second lower mounted wire on the utility pole.
      Ground -(green) – connects to the common (white) at the electrical junction box.
      Ground (utility) – Metal mobile home frames are grounded with a metal stake driven in the earth. When the earth is dry and rain begins to fall, standing on the metal steps to open the front door can draw a spark. Thusly, the purpose of the fourth ground strap.
