The dishwasher's junction box needs a ground, and I currently only have white and black.
Can the flexible conduit be used as a ground? If I can securely rejoin the flex to the solid conduit (using the clamp seen in the photo), I would still need a wire at the other end, from the flex to the screw. Maybe I just wrap a solid wire around the outside, sort of like this?
Or, could I run a new ground wire from the solid conduit, and into the flex? Not sure how that would work...
The junction box is the same as the one in this question. It's plastic, and has 3 screw-down connectors.
