comment Inferring wire gauge from cable size
I will open up the breaker panel and gauge the wires then. I could use the same trick to gauge the 2-wire no ground fabric-coated stuff, as well, rather than trusting they ran 14/2 W/G to 14/2 no ground. Thanks!

comment Inferring wire gauge from cable size
Using a magnifying glass is a good idea. I don't have one handy, but that's a cheap fix. I did manage to read the embossing on several more cables by turning out all the lights and then shining a flashlight on angle at the embossing, so shadows filled the letters. Some of it was still too worn away to read.

comment What to do with an apartment with only 2-pronged outlets
GFCI works without ungrounded cable because its purpose is to interrupt a ground fault by opening the circuit, not to ground power. It measures flow in and out, and when the delta exceeds a limit, it opens the circuit to stop the flow of current entirely. The assumption is that the missing current was diverted across your heart, and you'd appreciate living another day.

comment How can I trace cable through floors and walls?
@Tester101 Browsing the fox-hound/analog/digital toner listings on Amazon left me fairly confused as to feature and quality differences between options. With prices between $15-$75 for seemingly identical options, then a big jump to $500 for intro pro kit, I haven't the faintest idea what to get or what its real-life limits might be. Guess I could ask further questions. AC and EMT probably require different kit, like a magnetic stud finder or metal detector…

Given the state of the electrical wiring, I can't imagine them taking the trouble to pull cable they weren't going to use. Even if capped off, I'd still like to trace the cables to be sure. Same technique/tool (if it exists) would also come in handy when chasing wandering circuit paths between outlets.

Some rewiring was definitely done. It looks like a service panel upgrade for washer/dryer hook-ups followed by somewhat more recent work when most of the attic was finished. Ground floor is still serviced by fabric-wrapped 2-wire without ground, with the old service panel serving as an impromptu junction box (ugh).
