comment What “code” applies to projects that I do in my own home?
Once adopted as law, the text of the adopted version is no longer copyrighted. You can find recent code books in PDF format at bulk.resource.org/codes.gov. The PDFs can be large enough to make your viewer unhappy; I will print out 100-page runs to another PDF and view that, which I fine scrolls far better in my viewer.

comment Why am I measuring low voltage when I connect this fluorescent fixture to an existing circuit?
The setup isn't entirely clear to me. What are you touching the probes to in order to measure the voltage across the circuit?

The response is saying that you can't daisy-chain the L and N terminals, so no doing feed->Load1->Load2->LoadN. Instead you need separate feed->Load1, feed->Load2, feed->LoadN. This could be done by pigtailing all the conductors to a single feeder. Just be careful not to exceed the circuit and conductor amperage rating.

comment How can I run an additional electrical circuit to a wall mounted TV?
I'm pretty sure cutting holes in a faceplate violates its Listing. Wiremold is a better route if you don't want the hassle of fishing cable through a finished wall.

comment How can high and low voltage be mixed in a junction box?
2011 Oregan electrical codes (adopts NEC 2011 with amendments) have that at about 800.133(A)(1)(d) Exception 1. Exception 2 allows that it's okay if the power conductors are there solely to supply power to communications equipment, provided you keep them 6 mm from the communications circuit conductors. (I use Oregon because I didn't see any other state adopting the 2011 NEC at bulk.resource.org/codes.gov/.)

If you hate the sconce so much, don't look a gift horse in the mouth -- just replace it.

comment What's the best way of replacing a plug or switch in a house with aluminum wiring?
If you need to connect copper to aluminum, do not directly twist copper with aluminum. The two will eat at each other, and resistance and heat will increase. The only way to splice copper to aluminum safely is using a device listed for that use. Others here mentioned a wire nut that you can safely use instead.

comment What should I do with wires that are too large for back-stab terminals on a receptacles?
Just because a wire fits in the backstab terminal doesn't mean you can safely stick it there. The quickwire terminals of some older receptacles accept 12 AWG wire, but Code has since changed to restrict quickwiring to use with 14 AWG wire only.

You can put 15A receptacles on a 20A circuit. A 20A circuit is able to safely supply up to 20A of power draw. A 15A receptacle can safely supply up to 15A of power draw, which obviously can't exceed the 20A its circuit can supply. The T-shape prong on a 20A plug prevents plugging a device that draws more than 15A into a receptacle that can't safely deliver that kind of power.

comment Inferring wire gauge from cable size
I wanted to work out wire gauge from mid-run cable. It seems that's not really possible, so per @Steven's answer, I'll just use an AWG wire gauge directly on already exposed wire in the breaker box.

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.
