No matter how much I’ve seen, hardly a week goes by without finding something new and astounding.
I guess this is supposed to be bonding??? New wire in a 1950s house.
Looks like they built in some redundancy. A triple bond.
Perhaps an attempt to provide a grounding means for 3 prong receptacles?
Either way it is incorrect and should be repaired.
lol…things like this inspired the term “likely to become energized”
