[Build] electrical status

[jim]

   thanks for the note, neil. more or less your suggestions 
seem right to me. main consideration is to respond to 
priorities that the community resolves, should there be any. 

   maybe good to divide the overall job up into little tasks 
that are unassigned, then each pick a task depending on what 
we feel like, who's there to help, community wishes.... we 
could make a list (e.g. run pipe from southwest sub-panel 
along southwest wall, complete wiring within sub-panels 
(note: i think the northwest, aka "front", sub-panel will 
benefit from some sturdy posts that guide wires coming in 
from the top pipes around the bus bars, also don't use the 
top three positions...), re-group and switch workshop lights, 
re-group and switch middle classroom lights..., and so on. 
i might get around to making such a list and post it inside 
the "electrical storage" room. 

   i believe scott will wire the toilet and shower room 
interiors and present a pipe or box to the exterior wall 
that we feed, likely from the "kitchen" sub-panel. 

   tracks will be used. will they remain in place is the big 
question. 
   note i hotted up only one side of each of the two of the 
hotted up tracks, and i wired the one over the 
workshop-classroom areas backward (i'll go to the octal box 
and reverse the black and red connections so they conform to 
the other tracks, i didn't understand the construction at 
the time i hotted them up in a hurry). 
   (that said, what's the point of presenting both red and 
black to the track rails? maybe tie both hot rails to just 
one circuit, i.e. bridge the two hot connections in the octal 
box for the track. that spares people from reorienting the 
connection in the track and also spares a circuit.) 

   moving the light fixtures will be a multi-person job: best 
to remove the bulbs before dicking around with the fixtures 
themselves. i hope to try pointing at least one set of them 
up at the ceiling to see how indirect lighting works (also 
might help protect people below in the event that a bulb 
breaks). 

   i'm using black for receptacles and never for lights. red   <---!!! 
feeds lights and appliances. where necessary, black can feed 
appliances. 
   main point: never put lights and receptacles on the same 
circuits--if someone shorts a circuit (likeliest at a 
receptacle), the lights remain on--safety consideration. 

more thanks, 
jim
