wiring a 30 Amp Power Outlet 30A Circuit Breaker {{UPDATE}}

Seem like a lot of shade tree electricians here. I am also not an electrician but when running an outdoor box like that is 100’ away from the panel may require a breaker at the outlet. Code may also require not only a ground from the panel, but a local ground rod. If the box is mounted on a post you will need to have the wire up the post inside conduit with a water tight connection. As to the connections inside the box, they should be all to pugs as breakers always plug on to a Buss bar.
