First let me say that I view this forum all the time but rarely post. I have about 30 years in the trade and 12 years as an inspector in one of the busiest towns in NJ.
Here's the question, Can the feeder tap rules of the 2008 NEC 240.21(B) be applied to the solar connection that is connected to the supply side of the service disconnecting means as in 690.64(A)?
My answer would be no, as this is not a feeder and the tap rules do not apply. The first question I would have would be "what size overcurrent is protecting the feeder?" You would have to know this to apply the tap rules.
I have inspected hundreds of Solar installations and the solar equipment, or a fused disconnect for the solar equipment, is installed adjacent to the service disconnect. It is my interpretation that the conductors before the service disconnect are service entrance conductors.
Although I hope everyone on this forum agrees with me, if someone disagrees and thinks that the tap rules due apply please show me a code section that allows this. Also remember I am talking about connections on the supply side of the service disconnect, not back fed breakers.
