does anyone remember what year the color identifying the high leg on a 4-wire delta-connected secondary was changed from purple to orange? I remember working with systems that were marked with the purple tape on the b phase in the late 70's. This is of course concerning the NEC and not local codes. thanks

Dave, I was a young lad learning the trade and living in Michigan in the late 70's and have NEVER seen Purple used for high leg identification. Some have posted here that purple is currently being used in their jurisdiction.
 
Purple is still required here by one of our POCO's. They also require the high leg on the "C" phase. After the meter we change to orange to comply with the NEC and terminate on the "B" phase.
 
I, too, don't remember seeing purple. I do recall as a young tadpole that the center bus was always the high leg in a panel, but it was red instead of orange. I also see in other older services that it was red and on the right-most lugs in disconnects.
 
I have seen Red, Blue, Purple, and of course Orange used. I remember marking high legs Blue in the 70's, but these were in existing facilities where there was a standard already in place.

I started with the 61-65 NEC and I'm pretty sure it was orange back then

Dang Charlie, How old are you? If I recall correctly back then all that was required was that it be identified. Here in MI it was mostly orange, but red, blue, and brown have also been used.

110-15
230-56
408-3 (E)
409-102 (B)

NEC says orange and B phase however Progress Energy here in NC likes to put it on C

high leg

The utility guys say the high leg has to go through the meter on the right side for the meter to work correctly. And then it goes back to b phase in the panel. Identified with orange in my area.
