Katt's guide to AC wiring color codes!

Green: should be safe to lick.
White: might be safe, but inadvisable.
Black, Red, Blue: do not lick
Brown, Orange, Yellow: most definitely do not lick.

OH and this only applies to the US. Other lickability standards exist in different countries.

Katt talks about wiring phases 

So I feel like going on about this since I think it's cool.

Residential wiring is what's called split-phase. You have an A phase (default black) and a B phase (default red) that are 120V (RMS) AC sine waves and 180 degrees out of phase with each other. The voltage between the two phases is 240V (useful for things like heaters and large appliances). Neutral (white) is held to zero volts and serves as current return for both phases.

@starkatt You're making this more accessible than many manuals and books I've seen try to demystify matters! Keep going, please. n.n 👍👍
