Hi guys

I have a couple questions that I can’t find in the code book and did not know if they are.

I have always heard that you can not tape (identifying a ground or neutral or hot) wire under a #6 and also when identifying the wire at the termination you have to tape it 6" back is any of this stuff code because I am having a hard time finding it.

The common way to mark 480 is brown orange yellow but I can’t find that either I know that is how it is done but from what I am getting in the code book you can do whatever but it just has to be marked that lets say you use black red blue for 480. Is that right.

I have heard you can not run flexible conduit for more then 6' if it is exposed. I found that it said that in the code book for Greenfield but I did not see that for seal tight. Can you run seal tight as long as you want.

Thank you

Just some stupid things that we were talking about at work.

>> Nothing under #4 - unless it is part of a cable assembly. 3 bands encircling the conductor, is what I remember from the code.

>> The code is quiet on this matter - Other than taping the wild leg orange. Basically as B, O, Y or BK, R, BL - But what ever the color coding is on the premise, its wise to keep it the way it is.

>> You can run FMC or LFMC for as long as you want. However, some localities only allow 6'. The CODE says you cannot use it as an EGC on a 20A circuit if it is longer then 6', you need to run an EGC IN the conduit.

Thank you, I was looking to see if anyone knows the code #

Magnettica

200.6 (A) & (B) for the 6 AWG question.

Ok art 210.5 talks about identifying different phases and no there is no NEC requirement about colors other than neutrals and grounds.
Im working on the reidentifying smaller than #4 I know its true looking for art. Dont think it says 6" back, 3 stripes will do you.
See art 338 on fmc it can be run as long as you want if conditions are met.

You are required to tape or mark (I normally use a black felt tip marker) the hot or common on three way switches when using a three wire (e.g. 14-3 or 12-3 NM) and the white is the hot.

I doubt that the OP was refering to this.

Article 348 is about FMC.

Article 338 is about SE and USE.

250.119(a) talks about conductors larger than #6 being identified with at least 3 stripes for equipment grounding. Not sure if that was what I was looking for.

And 200.6 is for grounded conductors like someone above said.

210.5 C talks about the colors. In Wisconsin, Comm. 16 adds a Fine Print Note that recommends BOY for 480/277 and BkRBlu for 120/208., but it's just a recommendation. We have some GE plants in the area, and they spec just the opposite. Kinda freaky your first time in a panel.

350.30 A Exception 2 talks about the 3, 4, or 5 foot lengths for flexibility of sealtite.
