Can anyone tell me when the color coded insulation for the large (#4 and above) wire has been around? I sort of remember when I was in the field back in the late 90's and early 2000's that it was just coming out I thought. Back then, it was an adder to order it. So when did it become more prevalent?
The reason I ask is that I am doing a project of replacing a chiller and the facilities person is wanting the entire run of 2 sets of 400 kcmil cu to be replaced unless we can tell when they were installed.
