Greetings,
I have a mix of newer Romex wire and some original sheath wiring (house was built in 1950). I took down the drop ceiling in the basement and there were multiple wires that were not run properly through the joists; it was just laid on top of the drop ceiling "insulation/tiles". So, I'm trying to wrangle a mess and run all the wire through the joists like they should be. Luckily, some of the older sheath wiring would go to a junction box, and to another junction box and then to another. Where I am able to access the start and end of a particular section of sheath wire, I am replacing it with Romex (and elimiating as many "stops" in the junction boxes as I can). I do have some questions though:
There are a few junction boxes that I will have to leave the original sheath wire, because it runs up the wall to the main floor or upstairs and I can't access the wire to replace it. I paid attention to how the wires were hooked up in the junction box and took pictures with my phone. I want to double check myself when I hook everything back up. Obviously, Romex is easy, black is hot, white is neutral. When the newer Romex wire is feeding (incoming power) the older sheath wire, I want to be sure I hook it up correctly hot/hot and neutral/neutral. How would I make sure I know which is which on the sheath wiring when there is no power feeding it (can't use a multi-meter on a non-live wire, right?)
If I feed the sheath wiring with incoming power from the Romex, could I use an outlet tester on an outlet that is on that sheath wire circuit, past the junction box to check myself?
Or, before I hook up everything together in the junction box, could I connect the Romex feeding the power, the sheath and an outlet right there, just as a test? In other words, wire nut the Romex incoming power, the sheath wire and the outlet together and check it with an outlet tester. Would that double check me?
I should probably invest in a good multi-meter. Is there an easier way to check that I am overlooking? FYI, none of the older sheath wire is marked on the outside; I am going to mark it with black and white electrical tape at each connection point when I test it to be sure.
Thanks!
