According to Randy,
The 50A outlet is outside, and if you look close enough, dripping wet! (Its been raining here off and on the past couple of days.. and we're supposed to be in for a really wet New Years weekend. The large 3 phase disco used to protect the Zinsco subpanel to the right of it, but near as I can figure, someone bypassed it with #12 that you can see piecing things together in there... Nothing in that place made a whole lot of sense, but it seemed to "just work"... I wasn't even daring enough to put an amp clamp on the #12's to see what they were carrying!.
