Yesterday I had a fuse blow 3 times and I eventually tracked it down to an outdoor outlet that wasn't so watertight. The outlet had an outdoor cover on it but after opening it it was obvious that moisture and debris had been getting into the box. The outlet in the box also seems to have shorted inside and was actually rusted (may have been 40yrs old).
I bought another cover plate, but I really don't think a new cover plate with the foam insulator is sufficient. It seems like a regular INDOOR box that's been embedded into a brick wall. The electrical outlet is installed on the top of the box with the screws going into holes on the outside. I'd like to know how to properly close up this box.
Here are some pictures:
The circuit is also not GFCI protected so I'll add one to an outlet inside on the same circuit.
