Factory and typical not an issue.I am not familiar with this installation i.e. meter service panel combination.
First, there are extensions from the main breaker to the bus bars. Is this a modification? Why is the bus bar not directly connected to the main breaker bolts?
Likely a violation, would need more detail.Second, several NM cables enter together through the knockout at the top of the panel. Is this typical since they are not secured?
Violation.Third, the 12/3 romex on right side of panel is within a conduit that is installed outdoors (wet location)?
