I’m in the middle of an install by a solar contractor, and have a question on how they have the main panel breaker wired. This is a SolArk install, so the SA is powering the entire panel via the main 200A breaker. They specified 3/0 copper cable, but the 4-lug main breaker doesn’t support that large of cable, so they trimmed down some conductors to fit. They are only using 2 of the 4 lugs. Any concerns or code violations with this? They also have one of the screws pretty mangled, lost another one, then broke one lug completely off the breaker.
