[Build] Fwd: [Noisebridge-discuss] The electricians are coming! (today between 4 and 5pm)

I'm mostly a lurker, and don't even got to the space with any kind of
regularity, so feel free to disregard what I have to say.

However, I am a state licensed electrician.

It's a bad idea to put all the lights on one phase (which is hopefully
what all the red wires are) and all the plugs on a different phase.

Two reasons come to mind. One: if there should ever be a power outage
on one phase, you might lose all the lights. (Though this is unlikely)
Two: someone might want power for a 220v machine some time. You need
separate phases for that, and you should NEVER run separate phases
with the same color wire. IMHO, that's how someone will die/start a
fire/do other bad things.

That's just my two cents though, Neil and Tim probably also have input.
