this may be incidental but how far should the wire loop around a outlet terminal screw?
i have always looped almost completely around but the instructions for the new GFCI i am installing says 2/3 around?

does it really matter?

thanks

If you can get it all the way around then fine. But two thirds is OK as long as the wire can't slip out.

GFCI's normally use captive screw plates, and require no bending of the wire at all. Strip about 1/2 to 3/4" off the wire, insert it under the plate or in the hole and tighten the screw. Yours may be different, granted, but at Norm says, 2/3 is fine.

Too long and the wire can kind of squeeze out to the edge of the screw head, instead of being tight against the shaft and tight under the head. The more contact the better. 2/3 of a wrap is fine.

This is based on my Navy training about wires under terminals and wrapped around posts for soldering.

And I agree with Larry..GFCIs normally have a clamping plate either in the hole or under the screw.

thank you
i always try to get it all the way around, and after tightening sometimes the end comes around to actually touch itself at at the beginning of the loop.
any harm in that?
in any event i always strive to make the connections snug and secure
