Any building's electrical system is intended to serve the needs of the users of the building in a safe manner. However, we must work within constraints such as for our geography, regulations, best practices, and most importantly, the system we employ below:

System

  • Label the main electrical panel as "Main"
  • Label the direct sub-panels of the main panel with a letter, e.g. "A", "B".
  • Label each sub-panel that is connected to a first-tier sub-panel of the main panel.
    • "origin panel letter" + "sub-panel letter" + ... (for each sub-panel add another letter) ...
      • e.g. "AA" for the first sub-panel from panel "A"
      • e.g. "AAB" for the second sub-panel attached to panel "AA"
  • For each circuit, label each outlet, switch, and load with:
    • the appropriate sub-panel name (described above) + "breaker number"
      • e.g. All the outlets in one room that are on the same circuit should be labeled "CA4" meaning the circuit is on breaker 4 on panel CA, which is the first panel originating from panel C that connects to the Main panel.
    • the draw on the curcuit
      • e.g. 20 amps

Protocol

  • We are especially (not exclusively) updating our electrical system documentation on a room-by-room basis.
  • As we do audits and work on individual rooms, you should only use the system described above to map the electrical system as it is discovered.
  • All other systems will be overridden.
  • You can print this page and the building floorplan below in order to document the labeling you make on the actual outlets, panels, etc:
