I wired up a 30amp plug in my barn this weekend to power the travel trailer when it’s in the driveway. My barn is wired with a 100amp service breaker cabinet off the house main service, which was ins...

Is the barn a sub panel connected to the house main panel? Or direct feed from the utility transformer?
Does the barn panel have a ground rod or does it have a ground wire feeding back to something else?
Not that it matters but is the barn wired with two main breakers with split phase 240v service or is this just a single phase 120v service?
The barn is a 100A sub-panel fed from the house main 200A panel, not separately fed from a transformer. The barn does NOT have separate ground rod. In the panel in the house, the ground wire leaving the house to go to the barn panel is terminated on a common ground/neutral buss. That same ground wire at the other end that reaches the barn panel is also terminated on a common ground/neutral buss.
The barn has one main disconnect. It’s a standard SquareD 100A residential house panel.
Thanks for your help.
Since the barn panel is a sub panel to the house main panel it should not be bonded. Bonding both panels creates a ground loop that could cause continuous current flow thru that portion of the ground wire system.
I agree with this. Furthermore if the neutral wire fails you now have full rated current being carried by a ground wire which is typically not as large of a conductor.
