Guys, this workmanship is not that unusual. There should be a mud daubers nest and mouse skeleton in there where it crawled in via a missing connector.
Here you go...
Got the mud dauber nest. No dead mouse, just the mouse pantry. There were no connectors in the 3/4" knockouts on the octagon box, so the critter highway was 4 lanes wide.
Dug this gem out of my detached garage. Wiring was a cluster, EGC's all cut off, reversed L and N, romex subject to damage, etc. All since replaced with EMT, and passing through a 20A GFCI; there is currently no EGC connected at the house end. The 12 gauge UF going to the house is tapped off a 15A bedroom circuit. I hope to take care of that this month.
