Longest Length of A Run of Greenfield w/ground

[themadaman]

In a renovation and/or new construction situation what is the longest run a greenfield whip can be used when a separate ground wire is pulled with the other conductors? I am aware that 6' is the maximum length allowed between junction boxes ect... Are there exceptions to this?

You can run it as long as you want as long as a EGC is pulled.

Keep in mind that FMC is not a cable and the 360 degree max bends between pull points still applies. 348.26

If you're using the FMC as the EGC it must meet all of the requirements of 250.118(5). As Bob said there is no 6' limit if you're installing an EGC within the flex.
