Wow. This kind of thing happens to me all the time. I *still* haven't figured out all the quirks of the previous owner's wiring...
But what's this about new code changes? Did I miss something, or was your panel just really old?
Wish I had that kind of room!
Thanks,
Bill
Panel is probably original to the shop, 20 years or so old, newer panels have a separate ground bars for the neutral and ground to connect to. It's mostly to do with electronics. I'll have some computer equipment in the office of the shop. The current panel has only one ground bar, which the neutral and bare ground both go to. However they did run 4 wires from the main, two hots, one neutral, and one ground; which is the way it should be done.
They also had the subpanel grounded at the shop to a ground stake outside. This essentially creates a ground loop. When running machines in the garage it would cause the TV's and computer equipment in the house to flake out a little due to electrical 'noise', so I disconnected it.
Splitting the ground and neutral will further isolate electrical 'noise' both in the shop and a from reaching electronics the house.
