YES THE GREEN IS CONNECTED TO A FRAME GRD,THE BLK GOES TO L1 OR LEFT SIDE THE WHITE IS CALLED NEUTRAL OR IN THE MIDDLE AND THE RED GOES TO RIGHT SIDE.OR L2. RED AND BLK OR ODDSITE PHASE 110V AND THEY CAN GO TO EITHER SIDE SO WHAT IT LOOKS LIKE IS (BLK WHITE RED) GRN TO GRD. IF YOU HAVE OHM METER THEN THE L SHAPE ONE OHMS TO THE WHITE. DO NOT GET THIS WRONG. REF. ON NORMAL HOUSE WRITING BLK IS GRD AND WHITE IS HOT, BUT ON 220 WHITE IS GRD.
