JS: no. run 1" and take it from an existing 1" run, extending
the existing branch and diverting it from powering a track to
feeding a small sub-panel ("wires" not "cable").

JS: buy an identical panel and rip out its guts to
replace the guts of the existing front panel, which
shows serious damage to its busses.

JS: progress has already been made on this.

JS: latest tentatively agreed-upon plans include
diverting a second 1" pipe run from another track
to power a second small sub-panel somewhere "over
there".
the idea of two smaller sub-panels is primarily
to re-purpose existing #6 wire rather than buying
new wire and pipe for entirely new runs, and
secondarily to distribute power capability across
the space--we can tap sub-panels for power as we
decide in the future.

JS: yes, no. we cannot easily later put in three-
phase. three-phase requires four wires, correctly
sized pipe, and a three-phase sub-panel. Neil's run.
plan is to use the "stinger" leg of the three-
phase to power the oven and cooktop, possibly
some other devices.
if we install the usual split-phase panel, we
pretty much forever dismiss using three-phase and
we miss using the available power of the third leg.
