stranded wire and devices

I wouldn't encourage anyone to twist the wires opposite of their natural lay.
Best way is to do what was mentioned earlier. Use a pair of strippers or lineman's pliers, strip the wire back but don't pull the insulation off all of the way.
Ive done thousands of them that way and never had a problem (that I knew about)
 
It's also easy enough to pinch the hook closed around the screw with a pair of needle-nose pliers and hold it while tightening the screw. I do the same thing when attaching a wire to a grounding screw in a box.
 
Also, they are nice because you can put two wires per terminal, and only have to tighten once screw. Once you use BR receptacles you wondered how you ever used regular CR's. The high end federal spec and hospital grade stuff like the 5362 models also have the backwire feature.


You're not talking about using the device as a splice point are you ?
 
The twisting of the wires in the reverse direction works well because as you tighten down the binding screw on the receptactle, the clockwise direction of the screw will actually tighten the reverse twisted strands of wire. Without the reversing the twist the binding screw tends to "open" up the individual strands of wire.

Anyone have a copy of the current Electrician's Bible? Looking to see if it still recommended for # 10 and smaller? Have always followed the recommendation because of the way it pulls the strands in clean and tight(no free sparklers hanging out looking for action when the circuit gets tested to see "if it will let the smoke out").
 
Is it against the code to wrap a stranded wire around the screw terminals on switches and recp's? If so please give me the code section.

Massachusetts electrical code amendments 110.14 (A) deletes last sentence and adds terminals for 10 or smaller wire must be rated for standed wire or stranded wire must be made solid. We use fork crimps all the time with resi grade devices.
