The only torque specs for a duplex receptacle that I could find was on the Leviton web site (
www.Leviton.com). This is the statement from their spec sheet for the 5262-IG Receptacles –
Designed torque capability of +20 inch pounds.
Interestingly, I called Leviton and their Rep told me that all of their standard devices with screw terminals are listed at 12 in-lbs...
I said: "Man that's
light!" And he said, "Yes sir, 12 in-lbs."
(Oh, and Joe kept the second torque wrench without any prodding at all!)
