@GordonGFox You commented about a year ago about "heat shrink insulation". I just bought a 1925 house with a hodge-podge of misc. old wiring. I know I will encounter plenty of frayed old insulation as I go about replacing switches, outlets, and other basic DIY repairs and upgrades. Is that heat shrink stuff available at common home centers like Lowes or Home Depot?

What was the purpose of this video again?

My understanding is that nickel-copper got the nod because BARE nickel -- under lugs, etc. was superior to bare copper. So if the environment was nasty, nickel - plated copper would be spec'd.
Likewise tin plated copper is the NORM for high quality switchgear, that is, gear used in harsh environments or subject to intense loading.
Ordinary commercial/residential busses use aluminum. ( slightly alloyed)
The thick insulation dates from the sixties and before.
BTW, nickel too

id mount a blister on top, clean everything up in the panel, then splice everythng up top(or burndy them) then chase nipple down into the panel with the right colors/size for each circuit

Understanding the wiring in an electrical receptacleby easyplex425,756 views
purpose of video was to show difference in insulation type and thicknes used over the years for the same size conductor. When inspecting it is easy to think the thickness of the wire indicates the conductor size, not always the case. Older #12 awg looks a bigger than newer #12 awg

is thicker insulation is better , why were the old cloth type wires covered in nickel plating?
windoes98se 1 year ago
@windoes98se the older / thicker insulation is now replaced with newer thinner insulation with what is supposed to be better insulation qualities so they can use less of it.
the old copper wires were nickel plated because the old insulation used at that time was deteriorated by copper

i would have burned off the cloth and wrapped the wire with tape. the frayed parts just look like fire starters....

heat shrink insulation is a beautiful thing, slide it on, heat it up and looks professional, easier than using tape
