but one thing i did see the subfeed box where is the grounding bar ???
because i can see the netural and ground wires at one common bus bar there.
the other thing is that where is the uf wire clamp to hold it or the conduct is missing ??
when you work on that box did the inside cover is missing allready ??
myself i dont like to use the subfeed box on 4X4 at all not too strong there but can hold up ok unless it have 4X6 then it will be fine there
