I have always called that out as an improper installation, recommend repair as needed by licensed professional. The wires should be under the plate, the bottom one on your first pick looks like it’s about to come out. Any heat expansion/contraction and it will. Hell, they even made it twice as bad with a double tap on the one above it. I have typically only seen this setup with handyman work.
Those CH breakers with metal feet are approves for two conductors. It is not a double tap. And those are fixed plates. The wire DOES NOT go under the plate. It goes between the plate and screw as shown.
Sorry guys, but my research I did years ago tells me that the metal claw foot CH breaker does not allow two conductors. It is the plastic foot CH breaker with an oval pressure plate connection point that allows this.
Thanks. I’m glad to finally get some real clarification on which CH Breakers allow two conductors. There’s been a lot of discussion on this message board from other inspectors and Electricians with multiple different viewpoints but no real answer.
