Which one was pretwisted and which one was not? (Short or long pair)
(Don't flame me for the colors of the wires, I thought the twist would show better with the contrast...)
I used this technique on one pair of wires:
I stripped each wire 1-1/4" and pre-twisted with the lineman's pliers (my first pair... Ideal brand, not "Kleins") Then I snipped the bare twisted ends back to about 5/8" and installed the yellow WireNut by hand until I could tighten no more, then removed it...
On the other pair, I stripped 5/8" off and installed a yellow WireNut by hand three turns, then tightened it an additional 8 turns with the yellow "Ideal WireNut Wrench". Then I removed the wirenut for the photo.
Can you tell which one is which?
The pretwisted version only had three scratch lines in each wire from the WireNut spring, whereas the one done "my way" has 9 scratches where the spring grabbed. Three times as many...
Also, viewing into a light, there are voids between the wires on the pre-twisted version, none on "my way"... It's all about contact area and pressure, folks... (With a Cu to Cu connection...)
Oh yes, and if one used improper care when stripping the wire (and they "ring" it even just a little) the wires may break when done "my way"... but I've never had a wire break in many years with the way I strip wires. (Notice the only non-Ideal brand tool is the strippers... Hey I think Klein's are better... I'm not Ideal crazy!)
How about a picture and
1000 words! (sorry)
