* In 2021, Kent Cates (electrician) evaluated all our panels and wrote [https://drive.google.com/drive/u/0/folders/0B4_Q7DQvNFT-RFFCZmNQTWVMTXM a brief report] <blockquote>Inspection of Electrical System at Omni Commons - 4799 Shattuck ave - 2/5/2021. Main Electrical service is 200 amps, Copper wire Thhn. There are 12 sub panels throughout the building , Feeder wires are Copper THWN and THHN wire. Found 1 small panel that had Aluminum wire. Panel types were General Electric, Federal Pacific, Siemons, Industrial Electrical. Sub Feed wiring is in Conduit and MCC, wire type is Copper Thhn, THWN and some cloth covered  ires. No Aluminum wire was found. There was No Knob and Tube wiring found in the building.</blockquote>

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.

==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 [[Media:Panel Diagram.pdf|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 Construction and Maintenance Working Group|Building Working Group]].

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! Also see our power usage, floorplans, old breaker diagram, and cancelled panels.

3 of these panels are Federal Pacific Electric and need to be replaced ASAP: A, AB, BA

  • Main Panel (in ANV office, room E of rear [48th St] exit)
    • Panel A (adjacent to main in ANV office)
      • Panel AB (in basement next to N staircase)
      • Panel AD (located upstage left in N corner of W wall of ballroom)
      • Panel AE (located in storage room S of stage in N corner of W wall of ballroom)
    • Panel B (in Crow's Nest above stage in ballroom)
      • Panel BA (in rear ballroom balcony near S wall)
          • Panel BAAA (behind Entrance Hall counter on S wall)
    • Panel C (in Disco Room at base of ladder to DJ booth)
    • Panel D (in ANV office on E wall shared with Entrance Hall)
  • CCL Panel - (Located next to door into CCL / sudo room area) - Apparently not yet documented here?

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.

This panel used to be under the entrance hall bar counter. When that counter was demolished, this panel was moved to the wall.

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.
