The items that Joe has presented bring light to this discussion.
I mentioned that the Manufacturers do not specify the conductors must be pretwisted, so that would rule out anything on that side [such as the turned down inspection for not twisting the wires].
It's obvious to me that UL would not pretwist, so that gives the Manufacturers "No need to pretwist" angle more validity.
Now, seeing people in the trade use the wirenut twister bit [for cordless drills], or the hand crank twisters - which are produced by the same Manufacturers which make the wirenuts being installed - I wonder if this is acceptable?
Like everyone else, I have been pretwisting conductors [with Linemans' pliers AKA "Kliens"], trim them as needed, then land the wirenut firmly enough to hold as an Insulator to the splice - rather than the sole conductor. This equals out to a tightness which does not distort the wirenut, nor pulls apart from the "Tug Test".
I'll have to print this thread out and present it.
It will be almost impossible to not pretwist after doing so for 18+ years!!!
Now as to the taping of Receptacles thingee, that one just sounds weird!
I would like to see a design or safety issue concerning this!
