This page provides a "living document" of the Omni Commons electrical system. It is not necessarily completely accurate, though it strives to be, and is always important to get updated!
3 of these panels are Federal Pacific Electric and need to be replaced ASAP: A, AB, BA
Also see our page on power usage
Timeline
- In 2021, Kent Cates (electrician) evaluated all our panels and wrote a brief report

Panel AA
This panel was cancelled in April 2021.
Panel AB
This panel is Federal Electric and needs to be replaced ASAP.
In 2019 we added another circuit to this box to power lights & outlets in the secure storage closet above it. In the confusion, something may have been switched around. Liblens briefly lost power. Needs to be re-assessed and re-labeled.

Panel AC
This panel is Federal Electric but is no longer receiving power. It will be replaced with the kitchen remodeling
this panel is located on the East wall of the West pantry of the basement kitchen.
its feed was a 40A/40A double breaker from Panel A WHICH HAS BEEN REMOVED
this panel only powered the kitchen stove hood fan & light before this panel was then disconnected at its feed.

Panel BAA
This panel HAD Federal Electric breakers BUT is now only a junction box, and is no longer hazardous.
This cabinet is simply a junction box for a feed coming from Panel BA
in ballroom mezzanine and going to Panel BAAA
in Entrance Hall.
A screw prevents the door from being opened, and there is nothing to see in there.
Panel BAAA
Label -> | Breaker # | Breaker # | <- Label |

8 | 7 | Outlet next to Counter (1ft above floor) & Outlet under counter |
This panel used to be under the entrance hall bar counter. When that counter was demolished, this panel was moved to the wall.
Panel C
100amps
I couldn't find this panel to take a picture --yar
Panel D
100 amps
There is a wire in this box that comes from the other side of the wall, in a junction box 5' off the ground covered with a 2 gang Plastic Blank Wall Plate which is joined to wires assumed to go to outlets lower on that wall. But since we didn't see the expected result when we hooked it up, it's not connected right now. Also there are no available circuits left in this box. That wire is labeled inside this panel.
Fan Panel
It says "exhaust fan", but does not have power coming in, and serves no known purpose. Breaker was removed and front panel capped off with a metal plate. Feed wires inside are capped off. (needs updated picture)

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"
- "origin panel letter" + "sub-panel letter" + ... (for each sub-panel add another letter) ...
- 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
- the appropriate sub-panel name (described above) + "breaker number"
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.
