[Build] Conduits towards darkroom

there's a plan for the wires. read the entire text
below before doing anything--that way you'll have the
whole idea: better to know that before you start.
from the four square box in the storage room to the
octal box over the door to the darkroom, pull one each
of white, red, black number 12. use the wires that are
in the boxes along the wall (read the printing on the
side of the wire--look for 12 AWG). be careful to get
lengths that are long enough: the length of the pipe
plus ten inches at each end plus an extra 12 inches.
each length of pipe is ten feet. the four square box
in the ceiling is four inches, but you should wrap a
couple of loops or wire inside the ceiling four square
box (hence the extra 12 inches).
stretch the three wires out on the floor (measure
again to be sure they're plenty long enough).
pick a color and double an inch or so back on itself,
and tape it to hold the bend leaving the bend itself
pick another color, butt its end against the folded
back end of the first piece, and tape the two lengths
together to cover the butt joint.
lay the last length along side the first two but a
little bit behind the butt joint and wrap tape around
all three wires with enough wraps to ensure they don't
go to the four square box in the storage room and
push the exposed bend into the empty pipe run to the
push, push, push, push, push... until the wires
stick out of the square box in the ceiling.
you'll probably have to get up on a ladder and pull
the wires gently to ensure they point out of the box.
then back to the storage room four square box and
push, push, push, push... until you've pushed enough
wires to reach the octal box over the darkroom door.
there should be at least ten inches of each of the
three wires sticking out of the four square box in the
then back up on the ladder and push the exposed
bend into the pipe that connects to the octal box over
the darkroom door; make sure there's enough wire that
you can fold a couple of loops inside the ceiling four
square box and at least ten inches of each wire
sticking out of the octal box over the darkroom door.
that's it for that pipe run.
after you get that far, let me know, 'specially if
you want to start feeding the wire from the southwest
sub-panel to the storage room. that'll be pretty
different work, so don't just start doing before you
learn the plan and the new techniques.
with great thanks,
