Wire color...

[Al Skierkiewicz]

Whoa Tex,
I didn't say I would make the team remove it. I said I agreed with the assessment that green is a color used for safety ground. As such I would inform the team of my assessment and let them decide. Inspectors do have a responsibility to try and help teams. We are on the front line to help you be competitive because it is best for all involved. As green is often thought of as being a common/earth/ground/safety, an electrical person would walk up to help you troubleshoot and naturally think that the green is tied to battery common. If used in the output of a speed controller, that could allow a person to tie a meter or other electrical device to it thinking it was common and find a pulsed 12 volt signal there. Smoke may follow. In auto electrical, as Joe has pointed out, there are other color codes.
As always, teams have the right to question the inspector and ask the LRI for a ruling. An LRI will usually include the head ref and FTA in discussions that transcend the rules. As much as we try to help, teams often disregard our advice. A testament to this is teams who mount the breaker panel upside down and have breakers fall out or teams that attach chain sprockets directly to the shafts of CIM motors without the use of additional bearing surfaces and have the motors fail during a finals match. The list is long, these are just a few.
