277V color wiring re-tagged to 120V wiring

[cppoly]

If 277V color coded wiring has been installed already, can the conductors be tagged at the termination points to indicate 120V wiring? This way new wires do not have to be pulled.

The wise butted answer is a question... What is 277V color coded wire? :lol: The more serious answer is, I know what you mean, and since the code doesn't actually dictate the colors of the phases, just that they have to be constant, and it doesn't require the marking to be along the entire length of the wire, except for grounding and grounded wires...

Yes you can identify wires that are not white, grey or green to indicate a different color.

BOY, brown, orange, yellow . I know you know what I meant too. The key word I take away from it is "constant", would this re-tagging be constant? For instance, the situation is that 120V circuits have been pulled using BRB, blue, red, black. 277V circuits have been pulled using BOY coloring. There is one circuit that should be 120V except it has BOY coloring. Can this circuit be identified at the ends by BRB tagging so that BOY conductors do not have to be removed and replaced?

What I should have typed is consistent, not constant. See the similarity.:slaphead: Meaning that once a color code is determined for the service it has to remain throughout the building. Identifying with tape or spray paint is an acceptable method. The code doesn't place ANY restrictions on this for line voltage conductors, restrictions of size and color are reserved for neutral and ground wires only. If it were me, I would just tape the wire along its entire length in the box, so that another electrician (also like me) doesn't come along and think, what was this hack doing?

Why not use a labeler and label the now 120 volt conductors "120 volts" ?

That sounds like the easiest. Is it allowed in this case?

Is it still consistent labeling if no other conductors elsewhere in the system are identified except by color?
I suppose you could document the new labeling convention as being "color or Dymo label, with Dymo label overriding color" , and change all of the places where the labeling convention is posted.
