rec.woodworking the following:
If you only turn off one breaker, you will often get some voltage that bleeds
back through the neutral at the supposed-to-be-dead fixture. If you used a
meter as opposed to a voltage sensor, I'll bet that it's not the full 120 VAC.
Now - although this is not something that I have ever seen - expand that to
a 4 wire source cable (3 hots and a single neutral) to the first junction box
and you've brought that 3rd breaker into the picture.
4-wire cable? It's used in dryer cables but it's a lot larger than
what you'd find in a lighting circuit.
OTOH, "I have this wire, so I don't have to go buy 'new'."
I'm pretty sure this wiring is all original to the house, which was
commercially built.
That doesn't negate OTOH, "I have this wire, so I don't have to go buy 'new'."
Ayup. The sort of thing which appeals to guys trying to stay
under budget, be they DIY or Professional DIY.
