twists under wirenut skirt

Kind of a weird observation/question here.....

I was looking at a pack of nuts and it said to twist until "approx. 2 twists of the conductors are seen under the skirt of the wire nut.

So I noticed in my house someone twisted them quite a bit more than that, say 3 or 4 tight twists visible under the skirt of the wire nut....

Im guessing its a non-issue but is it frowned up to twist em' up good and tight like this? Are the overly twisted ones at my house stressing the conductors negatively?

No, they are fine. We twist 'em until there are three twists in the conductors beyond the skirt of the wire nut.

We also fail them if any bare conductor is visible under the skirt of a wire nut protecting a splice of current-carrying conductors, so I don't know how we could tell.

Are the overly twisted ones at my house stressing the conductors negatively?
Anyone who can use a pair of pliers to stress copper conductors 14AWG or larger enough to damage them has my respect. They need to quit doing electrical work and focus on their career in body building and strength training instead.

It can happen a lot easier than you think. I had two #14 solid conductors twisted with 9" Kleins 10 or 12 years ago and one of the conductors broke.

Usually the wires breaking is caused by nicking them when they're stripped.
