I couldn't respond to your post in the technical reference area to the thread entitled "valuable information here for everyone!", so I'll post it here.
I'm probably being a little too critical, but this one has always struck a nerve with me for some reason. The last 3 and 4-way switch diagram in the second link from the top violates 200.7c2. Maybe I'm being too picky, but don't you feel that any diagrams posted for the purpose of education should be void of violations? Otherwise the links are great! Matt
