OK this is pretty simple one, but I need someone to agree with me or set me straight...I was working with a buddies JW at a print shop(I help man his jobs from time to time) we were pulling wire in emt, I would ask him what colors and he would say red/black for ALL the 208 loads, but when I looked at his make up in the panel he spliced blue to some of the wires for the phasing, instead of laying out the circuits ahead of time(like anybody would do) he just pulled then spliced to keep phasing. Am I crazy or is this a violations? How is this different then taping? And yes it was #10 AWG so re-identifying isn't allowed, unless I am wrong!
Thanks in advance,
H2O

With regard to your last sentence, the general rule in the NEC is that if the individual conductors are available in different colors, you need to use the colored wire.
Re-identifying is generally only allowed when there is ho way to buy wires with colored insulation (like 500 kcmil).

Ghost.....
Sim-Pul (Southwire) has a rainbow of colors, up to 750KCMil including green.

thanks, I know you can't re-identify #6 or smaller. Just wondering if there was a reason or exception to splicing in the panel that would see this as anything other than what is was, which is re-identifying.

No doubt the guy is just playing games- he wants his work to 'look professional' while not actually bothering to BE professional.

Technically, I don't think you're actually required by the code to identify the phases at all ... the entire panel could use pink wire and still be fine. I believe the requirement to identify things by voltage and phase applies only when there are more than one power system in the building- say. 480/277 and 208/120.

Ironically, I'm currently involved in a job where the opposite situation developed; the wire crew pulled in three colors, then the service crew installed a single-phase service. There goes the color coding!

As for larger sizes, I have seen increasing numbers of contractors think they're now required to use colored wire, choose to do so for a 'clean' look to their work, or who think the inspector / customer "wants" colored wires. (I'm referring to the big stuff here, too!)

Now, while we're on the topic .... why is there pink wire, but no pink electrical tape? laugh

Leave the red tape out in the sun long enough and it will be pink

Re-identifying is allowed except for 200.6 for grounded conductors (white), and 250.119 for equipment grounding conductors (green) 6 AWG and smaller, except in certain circumstances, such as multiconductor cable.

No offense to any potential pink-lovers in the audience, but I think it would get red tagged if there was no way to tell Phase A, Phase B and Phase C apart from one another.

Why is there so much black electricians tape but so few black electricians?
