A little off topic here but it fits. uncle harry, I enjoyed your comment about marking conductors with the color orange. This color by NEC identifies the conductor with the highest voltage in a 240V, 3PH, DELTA supply. High leg, wild leg, crazy leg are all terms I have heard used. Any way my wife and I frequently argue about the colors orange and red, each accusing the other of being color blind.
The only other place I remember red being mentioned is as the "B" phase conductor of a 208-120V, 3PH WYE supply. Although I have never seen it printed, I have notice the color code used in US industry is as follows.
Black Power
White Neutral
Gray "
Green Earth ground
Green w/ yellow tracer " "
Red 120vac control
Yellow 24vac "
Blue 24vdc "
Knowing this it is very handy when troubleshooting an unknown piece of equipment. If nothing else just so you do not blow your meter up by not having set to the correct scale.
Anybody else experience this?
I also also enjoyed how people call a certified, tested electrician and are dumbfounded when he does not have a machine he has never seen before repaired and up and running in five minutes or less. After all he is a professional isn't he?
