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)

PP1-2

Small fuse box

Back of the shop, left of PP1-1, above the light switches.
Left fuse, exit signs.

PB1-1

An unremarkable box full of wires.

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.

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 two rows of 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 and one row in the arts area
• 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.
