I was visiting a retail greenhouse with my wife and found this power distribution center.
What interested me most were the "clear" low voltage wires entering the power panel. Tracing them, I discovered the "clear" wires are speaker wires from the paging built into the telephone. The "white" low voltage wiring also intering the panel comes directly from the phone.
Apparently, someone thought it was a good idea to splice low voltage speaker wires in the 120/208V panel - for safety!.
The open green and white conductors into the plug in the GFI box are for the festoon lighting.
What's with the white, black, green THHNs in a cord cap
You're right!. I didn't think that was a flex and it's carrying the wieght of that box. And judging by the green algae around and the plastic cover that sits over the phone, this area gets wetted by the in-house irrigation system too.
