Electrical

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 page on power usage

Primary Electrical System

 * Main Panel (in Phat Beets, room E of rear [48th St] exit)
 * Panel A (adjacent to main in Phat Beets)
 * Panel AA (in Phat Beets, on E wall adjacent to Entrance Hall)
 * Panel AB (in basement next to N staircase)
 * Panel AC (in basement NW Kitchen Pantry, on E wall)
 * Panel AD (located upstage left in N corner of W wall of ballroom)
 * Panel ADA (in shower room on E wall)
 * 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 BAA (on N wall of classroom between ballroom and Entrance Hall)
 * Panel BAAA (behind Entrance Hall counter on S wall)
 * Panel C (in Disco Room at base of ladder to DJ booth)
 * Panel D (in Phat Beets on E wall shared with Entrance Hall)


 * CCL Panel - (Located next to door into CCL / sudo room area) - Apparently not yet documented here?

X = Disconnected

Panel A


200amps

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.

Panel AC


80A from Panel A

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

Panel ADA


This panel is located upstairs in the "shower room" which also used to house a hot tub and laundry machines.

Panel B


100amps

Panel BAAA


This panel no longer exists, the cafe people took it out with the rest of the counter.

Panel C
100amps

I couldn't find this panel to take a picture --yar

Panel D


100 amps

Fan Panel
[yar will upload a picture]

230 amps, says "exhaust fan", we don't know what feeds it

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 Working Group.
