Hi everyone. I thought I would throw out a few more color codes that we use here in the US.

As you may allready know, black, red, blue, brown, orange, yellow, and purple are all used as hot/live.

White or gray is always neutral, except when used for a switch loop in a cable assembly and is properly reidentified.

Green or bare copper is always ground/earth.

Our UK members may find this interesting. The black/red color code is used here...for DC systems. Red(+), Black(-). In fact, I just finished wiring my dad's boat and all boat cable I used is black/red. There is a new variety which is yellow/red, to cut down on the confusion with black=hot in AC.

Our fire alarm systems use these colors:
-black/red for interconnection between smoke detectors and pull stations.
-blue/white for interconnection between horns and strobe lights.

Audio cable (with one pair) for connecting speakers (for a home theater, for instance) is typically black/white or black/red. The other pair in a 2-pair cable is usually yellow/green.

Thermostat cable for central air conditioning sytems is red, white, green, blue, and yellow.

Confused yet? [Linked Image]

If I think of any others, I'll post them.
