I’d like some advice to connect the main panel to the conduit. It’s 2” conduit to the outside which connects to a detached garage. The problem I’m not sure of is how do I go from this LB box to the main panel without hogging out the entire 2×4’s in between the two. It’s 2” conduit because a bunch was given to me. I’m running 3- #4 and 1- #6 through this.
