How should I label and organize my home electrical circuits?
I spent a couple hours this past winter mapping out my entire house.  

The fields on my spreadsheet are as follows for each box in my house (lights, outlet, switch, garage opener, anything):


Panel Breaker (examples A1-10, B1-10)
Drop # - the first box on the branch is simply labeled 1, second box 2
Notes - if I know how things are wired in the wall I will put a note like "wire goes straight up to attic from outlet"
Room of the outlet - each room with unique name (Bedroom 1, family room, den...)
Location of outlet in room - I use actual navigation directions and go from left to right on each wall.  So an example would be "West wall outlet #2" - meaning there was outlet #1 to the left of that on the west wall.
What the outlet does.
Other notes - I have aluminum in some of the house so I marked these here and marked if I have an extra wire for fan.


I could see wrapping the branch with yellow tape with BRANCH written.  You could also give every wire a unique code A1-4 = branch off of panel A1 and outlet #4.  This becomes hard to conceptualize if your branches aren't daisy chained but still works with notes.

My wife thought I was nuts spending a few hours doing this but I have already saved a ton of time.  If I need something off, I just pull up the spreadsheet.  Also this allowed me to transfer some of the outlets to other circuits or to new circuits - I had 4-5 circuits with way too much on them.  I am now down to 1 circuit that only has a little too much and would have never realized without the spreadsheet.
