Electrical
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.

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.
