|Some of these fixtures are pretty rough after thirty years of hard usage.
It is hard to believe the barns were originally built and wired by a master electrician.
What a rat's nest.
The National Electric Code specifies that "boxes" have six inches of wire available so degraded and obsolete outlets and switches can be pulled out and replaced. The guy who wired these barns begrudged even three inches and then back-stabbed the outlets. Bastard!
Even worse is that he passed bare, non-metalic wire through raw holes in the sheet metal siding. It looked like he knocked some of the holes through the sheet metal with a tire iron.
|This is more appropriate type of pass-through for plastic insulated wire going through a sheet-metal wall than to snake the wire through the hole with raw edges. Link
I don't begrudge the few extra cents it takes to buy the next larger receptacle to give me extra room to fold and pack wire. I don't begrudge a few extra feet of wire. I wince when I buy outdoor grade wire when I only have a foot or two exposed to the sun...but I do it anyway. Sure it takes longer to use a hole saw to cut a round hole and bang in a grommet to protect and secure the wire. But those are the right things to do.
The last barn will be a challenge. It looks like it has been rewired and relamped at least twice and the barn only has two working outlets and two more that were abandoned in-place. Go figure.
