OC , when I added the power for the 5er I also added another box next the main on the side of the house.The additional box is for a shop I'm gonna build and only thing tied to it is the plug for the 5er right now.
I didn't open the main box that was added onto. If the main box had the ground and the common tied together would if effect my GFCI plugs in the house ? They all work fine.
Thanks for the response
