Awl --
So I finally unloaded those 20 old #14 bx cables off the ancient upstairs fuse panel, onto a breaker panel downstairs, 7 (mis-wired) Edison circuits and all....
It went pretty well, with about half the bx cables able to reach the new panel, and half being spliced upstairs, via #14 wire in 3/4" Greenfield.
The advice here prior to the job proved invaluable, and **many thanks to all who offered their thoughts and hard-earned knowledge and experiences**. ahr is really a web-treasure.
But.... Holy shit, What a job!!!!. You might wonder, Well, what's so tough about DAT? I don't really know, as much of it is a bad fog now.
But, I can say that including the demolition (about 70 sq ft of heavy plaster/lathe wall, about 30 feet of 10" duct in about a 1.5' x 1.5' wood encasement), this was a 3-week job, many days 10 and 12 hours days. Admittedly some head-scratching time, but mostly back-breaking and finger-wearing labor. Including some moved appliances, gas plumbing.
What a I thought would be an afternoon's work would turn into days.... Good thing I'm not in the contracting/estimating business, dats f'sure.... And the cosmetic finishing still awaits, an even longer job. But everything is at least functional now.
But here's some weird/funny stuff I encountered.
- During the demo, I inadvertently cut a bx cable, an edison circuit. Would normally not be a problem, except the "red" had so faded that it is sort of indistinguishable from the white, ie, both appear tan/beige. Worse, I don't really know what these wires control, as the house was wired in a helter-skelter fashion, where one fuse would control a hodge-podge of outlets/lites.
How do I sleuth this out? It seems to me, for the time being, it would be best to keep both presumed hots on the same leg for now. Nothing is blowing so far.
- While unloading the fuse panel of its neutrals (first I'd remove the hot from the fuse, then the corresponding neutral), my main temporary neutral connection to one fuse panel became undone, unbeknownst to me.
As I unloaded the circuit neutral (hot already removed), there was still arcing. I'm assuming that with the main neutral removed, this neutral was carrying return current from *other* hots, with the current eventually making its way to ground (btw, these bx cables don't have a ground wire). Ergo, arcing from other hots?
Is this to be expected, with a main neutral removed?
- With a non-edison circuit (one hot/neutral) controlling a few lites/outlets in the kitchen, and all wires separated in a junction box from a demo'd wall, I noticed on separating out the old mess that I could get an outlet and lite to go in series, ie, both would dim.
I can readily see how this would happen in an edison circuit with a lifted neutral (in which both lites etc would be normal OR one dim and the other too brite), but I haven't been able to sketch out how, with just one hot, parts of the circuit would wind up being in series.
Is this normal with a lifted local neutral? Or does this indicate a fundamental wiring problem? How to sleuth?
