Wa2wise, mamills ... Great catches.
The breakers with the "x" marks are, in fact, off while I worked on those circuits. One of the circuits mysteriously stopped supplying power to the entire run, and all three were in the same pipe. You caught me working ... and doing so safely ... don't let anyone find out!
As for the small wires double-lugged to the mains ... by golly, you're right. I was so focused on the trees, I failed to see the forest. I was wondering what I would do for work Monday; now I have a customer to call upon.
