Panel AA

Panel AA

This panel is a mystery to us. We could not identify any use for most of the breakers, other than #9. I suspect it may have fed the former bar area fridges, appliances & outlets which were demolished in 2015. Perhaps the overhead lights as well.

AFAICT this panel only powers the kitchen stove hood fan & light. Nothing else seems to be effected.

Documentation Protocol

Any building's electrical system is intended to serve the needs of the users of the building in a safe manner. However, we operate within constraints such as the historical developments of the electrical system, regulations, best practices, etc. In order to reduce ambiguity and risk, we must use a consistent documentation protocol throughout the system to understand and share knowledge of historical, current, and future uses.

Naming Convention

• 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

Here is the OLD breaker panel diagram

Protocol

• We are especially (not exclusively) updating our electrical system documentation on a room-by-room basis.
• As you work throughout Omni Commons, you should only use the system described above to map the electrical system.
• All other systems will be overridden.
• You can print this page and the building floorplans above in order to document the labeling you make on the actual outlets, panels, etc.
  • After labeling and writing on the printed building floorplan, deliver it to any member of the Building Working Group.
