I was reading the following thread:

and it perplexed me. 240.21(C) is prefaced with saying you can have no OCPD if (1) through (6) applies. So I would think if your secondary panel is 100 feet from the transformer with a main circuit breaker, you wouldn't need a fused disconnect or circuit breaker within 10 or 25 feet of the transformer. What am I missing?
