Question:
Greetings,
Thanks for the NEC question forum. Here is the question: If a 1600-ampere parallel feeder is installed in (4) 4-inch PVC conduits, what is the minimum size required for an equipment grounding conductor for the feeder. Does this equipment grounding conductor need to be installed in each of the four PVC conduits? Thanks for your time.

Answer:
Hi Andy,
Thanks for the comments and for participating. Quite simply, the response is 4/0 copper EGC is the minimum size and yes, this 4/0 copper EGC would need to be installed in each of the raceways of this parallel feeder.
