If a circuit breaker is feeding multiple sets of feeder cables, does the equipment grounding conductor have to be sized for the breaker and be sized the same in each set of parallel feeders? Or can it be divided among the sets?
For example, an 800 amp circuit breaker feeds two sets of 600 kcmils. Is one #1/0 equipment grounding conductor (the requirement for an 800 amp circuit breaker) required in each set of cables or can the #1/0 equipment grounding conductor be substituted for two #4 equipment grounding conductors since there are two conductors being run in parallel?
