I guess all the people posting using B in a residential job, never use the structured wiring cans. OnQ, Open House, Leviton, etc... ALL!!! use A. I have never seen it otherwise.

I agree it's a pain in the butt to always have to look if the system you're using is wired A or B. But until these manufactures get thier crap together and pick 1 wiring scheme, we are going to have this confusion.
Pay attention to what your wiring and select A or B depending on what you're doing.
