Trumpy,
Wire Twister has the right answer. It is all about the money. However is this a "Conflict of Interest"? Wasn't there a problem years ago when a certain wire company got Aluminum wire approved to be used in houses? Remember what happened then? I also think that a code change every 3 years is too short. What is wrong with a code change every 5 or 6 years. I don't get the chance to write to the NEC code panel because I don't use the new code until a year or two later.
