10 years ago I had a workshop built off the back of my attached garage. At that time I installed a 50 amp sub panel in there.
This is a 1975 home and the main panel in the basement is a 3 wire so I followed suit and ran a 3 wire to the sub panel. My home is being sold and the home inspector told the buyer that the sub panel needs to be 4 wire.
The need for separate neutral/ground is understandable but how is this possible since the main panel is only 3 wire? I understand that a separate ground can be run but the 3rd wire already serves as ground so isn't that redundant?
Short of rewiring the entire house, how is this supposed to be handled?
Thanks for the help.
