First thats just the panel that is tucked and sealed in the stand.
Second. No water comes any where near it. Its in a cabinet that water is no where near. Even if i did overflow the 20L that sits on top of it, the way that panel is mounted into the stand is such taht its directly in the middle, and the back is sealed. There isnt any pipes or anything with water that goes through it.
Third, each connection is a spade connection so its not coming off.
Fourth, im not an electrician so its not pretty.
Fifth, its perfectly safe. No loose wires, No open conenctions. The plywood that its mounted to completely covers the screw connections where the wires attach. Wood doesnt conduct electricity last time i checked with a fluke.
I was just showing how i mounted the plugs for reference. The front which isnt show has face plates on it and is nice and clean looking.
