Thanks guys. I can't say I really noticed the different names used by various manufacturers == I'll have to take a closer look in my Graybar catalog and compare Hubbell, Leviton, etc.
Trumpy,
We're talking about the grade, or quality specification which American receptacles and switches are sold under. Hospital grade recepts. are the highest quality, and are marked with a green dot on the face.
Correct me if I'm wrong folks, but don't hospital-grade devices have to meet certain criteria for minimum tension on the contacts after X insertions/withdrawals?
