I have noticed different methods for terminating stranded wire to devices.

as not all devices are created equal,the method varies...

what i see most of is stranded made to devices that are meant for solid only without forks.

the wire is stripped, a small 1/8" piece of insulation is used to hold the very end from fraying, and the whole deal is placed under a device screw.

comments???

The UL White book receptacle section (RTRT) says: "Terminals of the wire-binding screw, setscrew, or screw-actuated back wired clamping types are suitable for use with both solid and stranded building wires.

I do this too. I don't really like it; the more you tighten the screw, the more the wire seems to get pushed out from under the head of the screw. But I don't know of any better way.

I've done that to in a pinch..

Ideal makes these forked terminals that are on the end of a little blue wire nut. They're much cheaper than crimp type, easier to use and look a lot better too. I use them if space permits, otherwise I use the ol' trick Steve mentioned.

If you twist the strands counterclockwise first, tightening the screw will further twist them instead of untwisting them.

I think that's if you are are inserting from the left side.

Where have I gone wrong?

I was always told to have the wire inserted with the turn of the thread ( clockwise ) and that would eliminate the insert from 'right side' comment.
Of course if the binding screw is 'counter clockwise thread' that would be a different story.
