Dishwasher Installation - Power Cord Ground Wire?
Question:Please excuse this simple question but I'd rather be safe than sorry. I've read the instructions a million times....appliance must be grounded but I don' t know what that means! Under the dishwasher I see a black wire (hot), I see the white wire (Neutral) and the green ground wire is attached under the head of a screw to the appliance - does this mean its already grounded? So now I purchased a universal 3- Wire Dishwasher Power cord. Obviously white to white and black to black but the power cord has the green ground wire..where do I connect this to? Would I place it under the same screw where the other green wire is? I have no experience doing this. Please help before I get electrocuted! It seems simple enough but I'll wait for some advice...and may be someone can clear up what hardwiring means?!?! Thanks in advance.
Answers:
Yes, attach the green ground wire to the screw (usually painted green) on the appliance. The metal chassis of the motor is the ground.
Hard-wiring the appliance in would mean a direct connection to an existing power cord coming out of the wall with no outlet.
I assume the universal power cord plugs into an outlet on the wall in the rear of the dishwasher. The cord should have 3 prongs. Two flat ones and a rounded one. The rounded one is the ground plug and it is connected to the green wire. Coonect the green wire on the opposite end of the cord to the same screw as the green wire on the DW. This will complete the grounding. If you did not have an outlet to plug into (just wire coming out of the wall or box) you would use electrical wire with 3 wires in it. A white, black and uncoated copper wire. The copper wire would be the ground and it would hook up under the same screw and be connected to the copper wire from the wall wire using screw-on electrical connectors. This would be hardwired.
