Bay 3 trifoam wasn't working

Never bring your wires in through the top of an electrical box in a car wash:



The butt splices are a temporary repair until I can relocate the box where it can be accessed more easily, terminate the wires from the bays there, run new wires to the pump stands (They currently run through this box and into the cabinet for each pump stand and then BACK to this box), then move the low pressure function wiring to the new box. So far everything else is working, but all the trifoam connections crumbled when I tried to splice the bay 3 wire.

There must have been an inch of water still in the box. The leak happened over three years ago.

Drilling a drain hole would have helped a bit. My line of thinking these days is that it seems no matter what you do there's a chance water will get in so let it out. Putting conduit in the top is just asking for it though.

I probably would have left the gasket off the lid if I had ever been in the box before. At least then the water would have run out.
