What's the better option on a dedicated ground?
What's the better option on a dedicated ground? A dedicated yet redundant ground, such as adding a ground rod in the crawl space under the outlet for all my electronics.... but it is still connected to the ground via my subpanel.
Or an isolated ground, I add a new ground rod for my electronics, but I disconnect the outlet's ground from the subpanel.
One small problem is the retrofitted grounds can not go the proper depth, there isn't 8 foot height in the crawl to go straight down. I can only go diagonal so the rod is more like 5 foot deep estimated.
How do I test the ground to see what's better in a scientific way?
I added a new ground to my subpanel and it made such a huge difference I thought I'd add one more.
