I just replaced my dishwasher, and noticed that the old unit had two wire connections: black-to-black wire and white-to-white wire. The ground wire from the home was exposed and wrapped around a screw on the unit.
Now, my new unit has a green wire for ground. Is it okay to simply connect the exposed ground wire to the green wire on the unit? The alternative would be to re-strip all of the wires so that the ground is not exposed (but, I'd rather not).
