Need some help here. 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 have attached a pic to help explain my plan.
