In the original picture, did anyone note the lack of paint and un-used clips along the top of the board, to the left of the disconnect? I would tend to think an "alteration" has occured here. One other thing, unless them wires are feeding the meters from the back, they aren't going into the tops of the meters, do you see any bends there? Or glands for that matter. It looks to me that the meters are only there for show.
I did notice that, Mike. What I think happened is that there was a piece of SE cable coming down the "mast" that ran directly into the disconnect switch. Someone decided to add metering after the fact, which is when it went from really bad to really, really bad. I zoomed the view and it appears that the meter on the right shows some wires coming out of the upper-right corner.
Regardless, the whole thing stinks to high heaven. Why there are three meters on what appears to be a single-phase installation is beyond me.
I'm sure that this installation is in Mexico. I've seen work like that everywhere I look when I've been there. Scary to say the least.
