How do I fix the AC unit to be connected properly to its circuit? How should the AC Unit/Garage/Subpanel be setup? Maybe I can separate the neutral and ground, then ground by connecting to the garage ground wire? If you want to note any other changes to make, you can do so.
Notes: The "Junction Box" is where the current electrical meter is located. A new meter pole was installed in the corner of the property. Thus, the old meter will become the "Junction Box". The "Main Panel" will have a bonded neutral and ground. The "House Main" will have a separated neutral and ground. The "House Main" will be grounded through the SER coming from the "Main Panel". The "Garage" is detached from the house and has an Ufer ground.
