After doing some yard cleanup, I realized that my panel ground wire was severed.
I went to Home Depot and was told that they only carried a temporary solution (see attached photo) and that I should seek a code compliant connector. I also talked to an electrician and I was told that to be up to code that I cannot use a connector and that I must re-run a new ground.
Unfortunately our setup would require us to run the new ground with new ground rods in a new location because the current path of the ground is no longer accessible (it's under concrete).
Can I use a "compliant connector" or do I need to run a whole new ground wire?
