Referring to 300.20(A), I have a single 800A 480V breaker feeding a distribution block through 3, 3" Ferrous metal conduits, approximatly 25'. This distribution block feeds multiple, lower amperage, fused disconnects. I am feeding the distribution block from the breaker with 9 runs, 3 per phase, of 250MCM. I was told it does not matter if you run each phase through its own conduit or combine 1 run of each phase through the conduits. I interperate the code to say that you must have 1 run of each phase in each conduit, essentially creating a circuit, to minimize induction heating. Am I correct?
