Power Panels

If you find out what a circuit breaker does, make sure it's numbered in the box and that information about what it powers ends up here. If possible, label the outlet box as well. What form this document takes remains to be seen; hopefully we will get a solid amount of information into it so further work on our electrical system won't totally be explorative.

First Floor

PP1-1

Back of the shop by the loading dock. Can't miss it.

Some sketchy shit in this one.

Single phase and 2 pole circuits wired to 3 phase breakers.

Several high amp 3 phase breakers that are unmapped.


Breaker # Used What Is It
8&10&12 unused 3 phase, 20 amp, 3 black. Wiring trough, boiler room. Dust collection circuit thru existing disconnect.
19&16&18 used 2-120v circuits on a 3 phase breaker. Blue wires. Boiler & zone pumps, this is bad and wrong.
22 unused this is a stray 208v single red wire on a 3 phase breaker that runs to wiring troughin the boiler room. Should be disconnected and abandoned.(used to be paired with wires pp1-2 # 35&37)


The following is the result of wire tracing done 04/25/2017. Tucker
Conduits from this panel were sharpie labeled with letters for this mapping.

Conduit Label feed path What It Feeds
A direct run across ceiling to junction in catwalk, from junction along catwalk and down to PP1-5 PP1-5
B Via PB1-2 to roof AC
C To junction above SE corner of boiler room, then to socket on boiler room wall Socket PP1-1:10 on small metals wall near S end of wall
D direct run to boiler room main boiler room feed

PP1-2

Back of the shop by the loading dock. Can't miss it.

Conduits from this panel were sharpie labeled with letters for this mapping.

Conduit Label feed path What It Feeds
A dead ends 20' into shop
B into PB1-2, through wall into dock 220V welder outlet on N wall above hydraulic pump
C into PB1-2, then to Pj1-1, then down to PB1-1 rear door exit sign, and sockets above PP1-1 labeled as PP1-1:10
D conduit runs to PB1-2, but has no lines no lines in this conduit
E Junction in ceiling above cold metals, which feeds 3 things:
  • hanging 220V 1phase twistlock above Johnson bandsaw
  • fat pipe out of junction to south takes 90deg east and feeds hanging 120V sockets over lockers
  • narrow conduit south takes 90deg turn and tracks back towards boiler room, feeding an unused junction/socket in the boiler room wall
    • 4th conduit from this junction goes north and dead ends
F direct to lights in ceiling Shop lights, 2nd row from the East wall
G direct to lights in ceiling shop lights, 3rd and 4th rows from East wall
H across shop ceiling and down East wall 120V outlet run along East wall of cold metals

Small fuse box

Back of the shop, left of PP1-1, above the light switches.
Left fuse, exit signs.
traced wiring 4/25/2017, and both fuses appear to feed the fans for the heaters in the ceiling, and the junction boxes next to the roof vents. While this fuse panel does feed into the junction that feeds the exit signs, it is just passing through and does NOT actually feed the exit sign: Tucker

PB1-1

This junction is fed by 2 different wiring paths:

  • The first wiring path comes from the small fuse box (listed above), and passes through the socket box labeled PP1-1-2:10, then through PB1-1 and up ~4ft to PJ1-1. From PJ1-1, it passes through PB1-2 and out too a conduit in the ceiling where it splits to feed the heater fans (with the exception of the SW one), and the junctions next to the 2 vents in the ceiling
  • The second wiring path starts at PP1-2, goes up the conduit labeled 'C' to PB1-2. From there it goes out to PJ1-1, and then down to PB1-1. From PB1-1 it feeds the exit sign over the back door, and the sockets above PP1-1 labeled PP1-1-2:10

PB1-2

Power box connected to PP1-1 by conduit. Bridges the A/C heat pump/air handler circuit, among other things. The 3-phase for A/c heat pump and air handler is bridged such that the entire 3 phase comes from PP1-1 up to the roof via PB1-2, and a branch switched on the roof by relay comes back down in the same conduit that goes the the roof. This circuit is passed via conduit to the air handler, and switched manually on the bottom of the air handler.

Below is the result of wire tracing done 04/25/2017. Tucker

This junction is a pass through for circuits from PP1-1, PP1-2 and the small fuse box.

  • Small fuse box
    • lines go through PB1-1->PJ1-1->PB1-2->roof and supply heater fans
  • PP1-1
    • This circuit feeds through the conduit marked 'B' to the roof and presumably the AC (see note from previous mapping)
  • PP1-2
    • from conduit 'B', the circuit feeds through the wall behind PB1-2 and into the dock, where it supplies the 220V welder outlet on the back wall above the hydraulic pump.
    • from conduit 'C' -> PB1-2 -> PJ1-1 -> PB1-1 -> exit sign over back door, and the outlets above PP1-1
    • Conduit 'D' connects PP1-2 and PB1-2, but no wires are run inside.

Light Switches

Upstairs

There are five lighting circuits upstairs, four of which are on three-way switches.

  • There is a switch next to the front stairway for stairwell and upstairs landing (the other switch is at the bottom of the stairs). Leave this light on.
  • There are three switches on the Arts side of the stairwell labelled 'Arts' 'Electronics' and 'Mid'. There is an identical set of switches by the door to the back stairway.
    • Arts is the lights on the arts side of the upstairs
    • Electronics is two rows of lights on the electronics side
    • Mid is one row of lights in electronics
  • Many of the fixtures in electronics have individual pull-switches (wall switch must be on)
  • The switch for the lights in front of the shelves on the north wall of the electronics lab is behind the shelves. Follow the conduit that comes down from the ceiling.

Shop

The shop lights are near the back door-- look to the left of the loading dock, to the left of the electrical panels with the clock sitting on top. There's a row of lightswitches with a red panel around them.

Unfortunately, there's no way to turn them on from the other end of the shop. There is one light that's supposed to stay on, but sometimes it gets turned off. There's a switch in the kitchen with a sign that says something like "don't turn this off", but it doesn't say why. I think there may be another switch somewhere else.


The "Don't turn this switch off" switch is a 4-way switch; the other two are 1: next to the back door, and 2: behind the CNC Bridgeport (which would be a useful place if we used that sliding fire door into the Abbey "lounge" area)


There are a few more lights in the shop that don't need to be left on overnight.1) above the woodworking sanding equipment- pull the plug. 2) to the left of the manual Bridgeport there is a switch controlling the lights overhead. 3) on the cold metals island there is a power strip for the lights above. 4) to the right of the sink in hot metals is a wall switch.


Lounge

  • Four switches by the front entrance that control the lights in the main part of the room
  • Two switches by the safe to the left, one for the safe lights and one for the short hall by the doorway to the shop
  • One switch to the right of the safe, that controls the outlet on the ceiling in the center of the room.
