I decided to add a small subpanel to accommodate extra outlets for my garage. I have an older Square D 100A main panel. Only cat no I could find is QOC-20m e6. First thing I noticed after pulling the panel cover to see how I should go about running service to the subpanel, is that all the neutral and ground wires are under the same lug per each respective circuit. Not ideal, but not unheard of.
Now, my question is, when running the neutral and ground to the new subpanel, would I connect both to separate lugs on the same neutral/ground bar in the main panel?
