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

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

Breaker # Used What Is It
6 Yes, works 20amp, 2 outlets hot metal side of furnace room, short drop near center of shop. Light in the boiler room.
8 Yes, works 20 amp, outlet at hot metal side of furnace room, possibly second outlet behind lockers.
7,9,11 yes. works. Power to chiller/heat pump on the roof for AC... and also the air handler under it inside. The
25 yes , works Lights at catwalk and kitchen, outlet at kitchen fridge.
26 yes, works Currently connected to the entire east wall. This includes dust collector and Clausing electronics. Please do not connect chop saw table to east wall while others are working.
35&37 used Compressor 40 amp 1 phase 240v thru a 35 amp disconnect in boiler room.

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.

PP1-3

Metal shop, by the lathes.

Breaker # Used What Is It
1, a&b yes, works 20 amp.
3, a&b  ?
5&7, a&b yes, works 50 amp, 240v, cold metal.
5b & 7a yes works 20 amp 240v, dedicated Clausing lathe.

PP1-4

In the tool cage.

Breaker # Used What Is It
12 yes 20 amp, 120v, south wall of the shop.
14 yes 20 amp, 120v, south wall of the shop.
18&20 yes, works 50 amp, 240v, hot metal at welding area.
23 yes 20 amp 120v, south wall of the shop.
24&26 yes, works 15 amp, 240v, shopbot.
37 yes, works 20 amp, 120v, hot metal at welding area.
