Yoopersup,
My point is that if you say that the screw that is used for the termination of the EGC must be a listed "green grounding screrw" there is no way to terminate the listed and labled lug used on a large conductor to the enclosure or grounding bus.
Ist the NEC code HANDbook is put out by the NFPA same folks whom bring us the code book. Its interpreations are accepted by most electrical inspectors
The interpreations in the code handbook are not the offical position of the NFPA and are no more valid than yours or mine.
The code does not intend that the only screw that can be used to terminate an EGC is the green 10-32 screw. Can you provide the UL listing category for a "grounding screw"? I haven't been able to find it.
