I found this snippet when researching re-identification of grounded conductors (neutrals). I had a panel recently with a few red wires used as neutrals. I called it out for improper identification but was under the impression some white tape would do it. According to this, that is not acceptable on 6 awg and smaller cable (at least in MN). I’m a little surprised by this. Anyone know the reasoning?
You’re probably right, code wise they should have run the proper colored conductors in the raceway in the first place. I don’t see any real issue with taping a #10, #8, or #6 conductor either.
