In the 2020 Edition of the National Electric Code, in Section 110.15, titled High-Leg Marking, it states, "... only the conductor or busbar having the higher phase voltage to ground shall be durably and permanently marked by an outer finish that in orange in color or by other effective means." An other effective means may be marking engraving with "high" or the voltage.
Obviously, only the highest-voltage leg shall be marked with an orange outer finish or with "high". However, does it mean that only that leg should be marked at all, or does it mean that orange or "high" is allowed on only that leg, meaning that other legs may be marked with other colors or words less strong than "high" such as "medium" and "low"?
