We were building a 400amp 3 phase service.
Out from the meter cabinet we went into a 400amp fused disconnect. From there we wanted to feed each of 2 Main breaker 200amp panels. My idea was to run 2 - 2" conduits, from the disconnect. one to each panel. the panels were 10 feet from the disconnect. I assumed that this could qualify as a tap. It's effectivly the same thing. The inspector violated it and said these were parallel conductors not a tap. I quoted 240-21D to no avail. Who is right?
