Hi, I have recently purchased a home that I believe has some K&T wiring still in use. I am not 100% certain of this however and I have hired an electrician to come out in about a week to check and see exactly how much is present and still in use, but I'm trying to educate myself at the same time. I don't know much abuot what it looks like than the pictures I've seen online. There is a light fixture in our attic that I believe may be knob and tube wiring but I cannot be sure. Hoping someone can look at the attached image and confirm whether it is or not. Thanks!

I would like to clean up a 30-year-old panel that is obsolete and a potential hazard. I want to replace my GTE / Sylvania (Zinsco-compatible) breaker panel. A problem is that this panel is about 12" wide and is flush against studs. Rather than carve up the wall to put in headers for a wider panel, I came up with "Plan B". My "Plan B" is to: 　 (1) Mount the the wider panel (a Square-D Homeline HOM20L125C) one stud over (next to the existing Zinsco), (2) Pull all the guts out of the Zinsco except the ground bar, and (3) Turn the Zinsco into a large junction box, both for feeders and circuit wiring. 　 I can cut a nice neat rectangle in the drywall for the Homeline with some vertical play to match up holes through the common stud and between the two panels. I expect to have to cut new knock-outs in one of the panels. 　 [Q1] The Zinsco is fed from a 100A main disconnect outside. The #2 AL feeders may not be long enough to connect to the lugs in the Homeline. I have not encountered AL-to-AL connectors for #2 wire. If not long enough, what is the best way to extend these feeders -- less than 12"? [Q2] Ground continuity to the outside disconnect panel is through Rigid Metal Conduit and a separate #10 Green from the outside panel to the ground bar. There is also a #6 Green from the ground bar to a pipe somewhere. Is it sufficient to run another Green from the Zinsco ground bar to the Homeline ground bar? Or should it be run from a connector attached to the RMC? What gauge wire should this be? 　 Thank you, Lynnx
