OK, so an attempt at creating a prioritized task list:
1) Put the front panel back together, possibly replacing some or all of it.
If I understand right, this item will bring power back to the front end of
the building?
This is a day's work for one or two people?
2) Run 1.25" conduit and wire to the Kitchen area, and mount a sub-panel on
the pillar there
This is a day or two's work for two or three people?
3) Run 1" conduit from existing branch to the shop, install a sub-panel
A couple of hours to a half day for one person?
4) Create some local runs in the shop
A couple of hours to half a day for one person?
5) Create some local runs to the kitchen
A couple of hours to half a day for one person?
6) Finish tracing and labeling the front panel
A couple of hours work for two people?
Some definitions:
"A person" is "a person knowledgable about electrical," except where there
are "more than one person" where it includes one knowledgable person, and
other people who are willing to do what they're told.
Hours above are task-hours, so "a couple of hours for a couple of people" is
four man hours; however, it seems to me that above is about as paralellized
as it can get?
Thanks guys,
