My home wiring is copper/white/green but the new dishwasher is black/white/green. I thought copper meant ground so I'm a little confused by the green being ground and what should connect to what.

    Your general location might matter. North America orange/copper can be used as a hot/black wire colour, but unusual. Would be found more with conduit than wire cable system. Ground can be only green colour(yellow stripes allowed) or bare(no insulation/copper)

    The insulation is ORANGE. The wire inside it is copper. "Copper" as a wire color implies bare uninsulated wire (or wire that should not be in your house walls, like cheap clear speaker cables)

1 Answer 1


If you are in the US, your "copper" is really orange and designates a hot wire. Connect it to the black on the DW. ( be sure the power is off)

White to white

Green to Green
