You're saying I can run the vacuum pump in building 2 off the generator fed panel in building 1 if I first terminate the branch circuit in a service rated disconnect in building 2 and bond the equipment ground to the buildings ground system. I then need labeling in both buildings. If you or anyone knows code reference for this installation (including labeling requirements) I'ld appreciate it. I'm sure I'll be dealing with an AHJ on it. Thanks, Pat.
