I have dc generator 15kw 48vdv with 250 amp interior generator breaker. The gen bkr terminals has 2 - 2/0 awg conductors feeding cell tower equipment which has dc battery. The dc generator is grounded with #2 awg GEC going to ground ring. The cell tower equipment enclosure with battery is also ground to the same grounded ring with GEC size of #2 awg.
What nec rules need to be followed dc site above in terms of EGC, dc generator grounding and conductor sizing. Is 2/0 awg size ok per nec? Also do I need to run equipment ground conductor from ec gen to the cell tower equipment? Dc generator rules of 250.30 apply separatley or non separately derived?
