According to nec 210.5 C 2 and although i have never seen it done, it is apparent that larger wires in pv can use green insulated wires and cables for ungrounded "hot" conductors 4 AWG or larger.
According to 210.5 C (2) where a branch circuit is supplied from a dc system over 60 volts and 4 AWG or larger, only its terminating and splice points are required be identified by polarity using MARKING TAPE, TAGGING OR OTHER APPROVED MEANS.
There is no notations in this code section of dissallowing white, gray or green conductors as there are in other sections.
Key point us that identification is only required at sectional wire terminations and splices.
Im wandering if this was NEC intent to leave this out?
