2 feeders, 1 building

[brian ploskunak]

I am installing a 120/208 volt panel and a 277/480 volt panel at a separate building. Both feeds come from the same main building. Do I ground both panels to (1) grounding electrode system at the separate building?

Yes, see 250.32(A), 250.50, 250.58.

Yep, 250.58 says it right there in black and white! Thank you George.

De nada.
