Maybe that's not a transformer. Looks like they are red and green wires for telephone use. Maybe this is the demarcation point for telco.

Why does the floor appear wet?

A sub panel needs 4 wires. This one is missing a ground. Also you cannot run the load circuits through the same conduit as the feeds.

Also, you cannot have wire sheathing that far inside of the box. I think 1/4" max inside the box.

Guys, this circulator does not run constantly or you would have hot water in your cold supply. Instead of running the shower for several minutes in the morning until the hot water gets to the shower head from the tank, the user will push a button located in the bath room so the circulator displaces the cold water in the hot lines. By doing this consumes no water at all.
