switch legs

[frizbeedog]

The 2008 code requires identification by both phase and system for branch circuit conductors in builings that have more than one voltage system. It would have to be the same color as the phase conductor or permanently posted chart at each panel would have to specify a second color or means of identification for the switch legs.

To use color alone for both the hots and the switch legs you need the 3 phase colors for each of the two systems and then 6 more colors for the associated switch legs.

So, twelve colors if I'm using the second color group which has been specified and posted at each panel as unique to the phase it has been associated with? Have I got that right?

What if 12-2 mc is ckt 4?

Colored tape.

so you could use any color switch leg longt as you identify it with tape or maybe a number?

Our local AHJ is relaxing the requirement for colored MC. According to our vendors, the company I work for is the only EC in town that uses colored MC.
I recall a two day lead time on some red/blue 12/3 MC I ordered last year.

I used some purple/yellow 12/3 MC to feed a string of lights (ckt 5 i.e. purple in this town) in a bathroom hard ceiling. The purple was for the constant hot to the emergency ballast and the yellow was the switch leg. I could have purple phase-taped the yellow, but I didn't, because IMO, the somewhat universal "field" system of conductor ID works just fine.

Yes, assuming that is what your posted identification directory says.

good because i just pulled a ton of 3ways and 4 ways. I used different colors for ease of identification for me then just taped and numbered them when i was all done.

But did you use the same method for all of the A phase conductors and is the method used on you posted directory at each panel? Note, this only applies to buildings with more than one voltage system.

i posted it at the lighting contactor, the panel is all the right color wire
