Hello, I'm new here and seeking some advice. First off, I'm in Louisiana. My area uses the NEC 2008 as the electrical code.
I'm planning to run power to my detached shop soon (hopefully). When we built the house, I spoke to the power co. and asked the best way to prepare for bringing power to my shop. I wanted 200A for the house and 100 or more to the shop. They sold me a Milbank 320A meter socket which has double-barrel lugs. One barrel of the lugs feeds the house. The other will feed the shop. I intend to install a 125A panel at the house. That will feed another 125A panel in the shop. I'm sure I can just feed straight to the shop, but I figure it would be convenient to be able to cut power to the line feeding the shop if ever needed. The panel in the shop will have a main breaker. What I'm unsure about is should that first panel at the house have a main breaker plus a 125A branch circuit breaker to feed the shop panel, or should it just be a main lug with a 125A branch circuit breaker feeding the shop panel. Keep in mind the panel at the house will only be feeding the shop, so there will be no other breakers/circuits in it. As per NEC and best practices, which is the correct way? I've attached a picture to hopefully explain my plan better.
