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
>> Nothing under #4 - unless it is part of a cable assembly. 3 bands encircling the conductor, is what I remember from the code.
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.
>> 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.
I have heard you can not run flexible conduit for more then 6' if it is exposed.
>> 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.
Poor planning on your part does not constitute an emergency on my part.
