   what do you think that we map the circuits at 
this point? neil knows a lot about electricity and 
could help if you don't know what to do. 
   mainly, figure out which receptacles, lights, 
tracks, and any other electrical things are 
connected to which circuits. 
   GOAL is to mark receptacles, switches, lamps, 
pipes, etc. with numbers that correspond to sub-panel 
circuit breakers. 
   sub-panels are 
* Rear 
* Front Primary 
* Front Secondary 
   circuit breakers are installed in positions that 
are numbered starting with 1 at the top left and 
increasing down the left column then resuming count 
at the top of the right column down to the bottom of 
the right column. 
   some positions have two breakers in the single 
position, so the top breaker is A and the bottom 
breaker is B. 
   in the Rear sub-panel, in position 1 there's a dual 
breaker R1A and R1B. in fact, if you look carefully at 
that breaker you'll see it's really four breakers, R1A, 
R1B that's tied to R2A, and R2B, all in a single 
breaker case. So notice that a single case may occupy 
more than one position. In the Front Primary sub-panel, 
there are 12 positions down each side, so top left 
position is FP1 and bottom right position is FP24. 
   for the Rear sub-panel and the Front Secondary 
sub-panel, the mapping instructions will work. 
   because the Front Primary sub-panel is torn apart, 
there's no way to tell which wires connect to breakers 
in which positions. either skip mapping the Front 
Primary sub-panel, or label each wire that sticks out 
of the pipes that connect to the Front Primary sub-panel 
and use that label name to mark pipes, receptacles, 
switches, etc....
