Appears no one so far has ever wired a house or paid much attention to how its wired. Takes about 90 seconds and a flat blade screw driver to see for yourself what is going on.
It’s a very good idea to understand how a house is wired. It’s an extremely bad idea to mess around the utility box with a flat blade screwdriver. Instant death can occur if you don’t know what you’re doing.
