An excellent posting.
i think I could answer about 50% of the questions. Terminology has
changed as has most of the technolgy. And some of the assumptions
too.
I had never heard of a Nearnst lamp or a Cooper Hewitt lamp.It was
interesting looking it up in Wikipedia.

8. What are the distinctive features of the different kinds of metal
conduit?

They had metal conduit? When I bought my first house in the mid 70's it
still had "live" gas pipes in the wall from the original gas lighting,
although it had been modernised presumably around 1912. The lighting wires
ran in surface mounted E channel wood sections with a pinned-on cover, each
channel carried a single conductor, rubber insulated and cotton covered. At
least the power circuits, such as they were, were mostly PVC (some
lead/rubber).

When I were a lad, we removed lots of metal conduit from house. It
had a seam and the joints etc had clamps. We also removed "capping and
casing" as it was known, wooded channels with a wood cover and "VIR"
cable. (Vulcanised India rubber). Perfect for starting a fire as it
deteriorated.
There was also a systyem of running rubber cables on the surface with
porcelain cleats.

My parents house was wired in more modern times, 1950. The mains cable
was pinned to the walls and sheathed in lead. Be worth a fortune today!

I still keep coming across disused bits of lead sheathed cable in the loft
of our 1930's bungalow. Surprisingly the insulation looks to be in
remarkable condition where it's been exposed at the cut ends - not that I'd
suggest that it would still be safe to use. A "junction box" for the lead
sheathed cable I came across looked quite scary though - a thin piece of
metal sheet with 4 cable clamps equally spaced round the edge and a
porcelain terminal block in the middle, it didn't look as if it ever had
any sort of cover.

We've still got a lot of cloth-covered/rubber stuff in our place (built
1949) - they replaced the accessible bits (e.g. most of the ground floor
due to access available via basement) but the lighting and top floor is
still mostly the old crap.

There's even evidence of knob-and-tube wiring in some of the outlying
buildings, although it's long since been replaced with more modern stuff.

No. This was either a DC system where two voltages were available
from a specialist generator or an AC system where the secondary on the
transformer was centre tapped.
There was no national grid in those days. People that had electricty
generated their own or it came from the local factory/mine, there was
spare capacity at night when the work force went home. There was a
myriad of different sytems and voltages.
I remember learning about such things at college. Never saw one. I
did work on DC for the local trolley buses but it was rectified from
AC. (Mercury arc rectifiers)
