Roger,
It's in 310-12(c) ('99, my '02 isn't handy)
"Ungrounded conductors shall be distinguished by colors other than white, natural gray, or green"
Now, what about a LV thermostat cable that has a green conductor?

1999 310-12(c) Ungrounded Conductors. Conductors that are intended for use as ungrounded conductors, whether used as single conductors or in multiconductor cables, shall be finished to be clearly distinguishable from grounded and grounding conductors. Ungrounded conductors shall be distinguished by colors other than white, natural gray, or green; or by a combination of color plus distinguishing marking. Distinguishing markings shall also be in a color other than white, natural gray, or green, and shall consist of a stripe or stripes or a regularly spaced series of identical marks. Distinguishing markings shall not conflict in any manner with the surface markings required by Section 310-11(b) The wording was changed for 2002. 2002 310.12(C) Ungrounded Conductors. Conductors that are intended for use as ungrounded conductors, whether used as a single conductor or in multiconductor cables, shall be finished to be clearly distinguishable from grounded and grounding conductors. Distinguishing markings shall not conflict in any manner with the surface markings required by 310.11(B)(1). [This message has been edited by iwire (edited 05-29-2004).]

That is interesting, that the'99 wording was changed in the'02 for distinguishing the color coding of ungrounded conductors - I wonder why sometimes a good thing has to be changed.
Back to the topic: Making fun of the pictures is fun, but it hides the fact that there are big problems out there. It has become almost epidemic in proportion how much of this type of wiring is going on today. It is a sad state that the almighty $ and lack of education has brought our society to a dangerous level of safety to save a buck. Even worse is these people (both the installer and the cheap customer) have put the good electrician's name in bad light. What I mean by that is whenever there is a fire these days, the first question is "was it started by electric". Like Joe Tedesco has stated, SOME HOW WE NEED TO CLEAN THIS UP!!!!!
I know it shouldn't, but this kind of stuff is really starting to make me sick.

When I see someone who obviously has $$$, yet went to extremes to get something "on the cheap," I delight in charging them a premium to get it working! Such folks deserve no sympathy.
Rule of thumb: if your car, house, etc., are nicer than mine, I am the one who deserves a break!
