I have an old house, ca 1928.
A lot of the wiring is old. A lot has been replaced over the years.
I'm not an electrician but I am very comfortable doing wiring. But I don't have the experience of an electrician to be able to answer what's up with this particular wiring.
Into my breaker box, one of the sets of wires is a large, multi-wire, metal-sheathed cable.
This cable has 3 Red, 3 Black, and 3 White wires.
This is 14 gauge wire.
2 of the Red are not in use -- they are each coiled and capped with wire nut.
The remaining "hot" wires -- three Black and one Red -- are set into 15 Amp breakers.
The whites all go to the common return.
Is this typical? Using a huge, multi-wire cable, to feed the rest of the house?
I'm not sure why there aren't 4 white returns. Or, rather, an equal number of hot wires and return wires. Is that also normal? (It's possible I mis-counted, though, the wires are a mess)
Should I treat this bundle any differently than any other wiring?
