We have a 1500 sq foot barn on a concrete slab about 200 feet away from our house. The electrical supply is a 40amp breaker with a 8/3 underground cable. I wired the barn myself, but I never put in a specific ground for the barn directly from the barn's breaker box into the earth...
The grounding for the barn is from the barn's breaker through the grounding wire in the 8/3 feed linked into our house's ground. Is this ok? Is it safe? What do you think? Should I add a specific ground for the barn?
