What is a “spy yard”. And the 4 pole breaker? Only the neutral conductor has colored tape ... is that ok?
the close-up of the cables in the clamps ... too many per clamp? And looks like the clamp screw is biting into the jacket. But the clamps are not snug.
That is not a 4 pole breaker, it's 2 pole that uses 4 pole spaces. ITE Imperial Corp., a predecessor of the company Siemens bought was the first to introduce those mains way back in the 1970's, Cutler-Hammer, & GE, followed in doing so.
