OK, all kidding aside I can't believe any Insurance carrier or agent endorsed that video pile of dung.
If any Litigator stumbles onto this video in the course of preparing suit against a Carrier or agent I will be happy to be a COMPENSATED Expert for you and even explain in greater detail what is wrong in that video.

To begin, note the use of Micronipper double blade wire strippers. These are NOT Ideal design strippers with blades that don't engage the conductor, the strippers in the video actually notch the conductor at the point where the insulation begins to be removed, they continue to plane the conductor all the way to the end. You get caught with these type strippers on a Federal job you and your tools are leaving the job.
That initial notch will grow and cause conductor fracture on stranded wire over time, sooner if vibration is present. The planing is loss of conductor capacity.

I really enjoy the demonstrator pointing to the pair of bypass strippers and saying he doesn't like them. Probably because they do less conductor damage.

Moving on from the damaged conductor issue, the actor tells us how he twists the stranded conductor. Get caught doing that on a job and you're headed down the road. Stranded wire is manufactured with a twisted lay to the individual strands to keep them in proper orientation in the bundle, and exceeding that lay by twisting the strands is not acceptable as a terminating procedure because it adds stress to the joint and leads to failure from vibration.

Then the actor mentions corrosion. No schmidt Silvio. 10 to 20% of the population exude a corrosive element in their sweat, you just put your paw on that bare copper that was cleaned before it was insulated and you think it might corrode. You completely skip the usually mandated and often ignored dip of the conductor into an anticorrosive grease. Stick with your acting because you lack skill in electrical assembly.

Lets move on to his crimper. That's a T&B design hand crimper and has been around industry and electrical trades for over 40 years from multiple manufacturers. They are expensive and they are one of the best crimpers made. Every one of the 9 I picked up and looked at today is clearly stamped on the jaws. There are 2 (two) crimping positions in the jaws of that tool. 1 is for insulated terminals and the other is for noninsulated terminals.

Mr Video Presentation is proudly crimping plastic insulated terminals with the jaw for bare uninsulated terminals. His crimp is definitely overstressing the individual wires in the conductor, even if he didn't twist the strands.

But he's not done.

He moves on to expound on heat shrink covered terminals and demonstrate the misuse of the Butane powered shrinker. He scorches the heat shrink and proudly proclaims the insulation is a pretty good seal with the wire insulation.

My hunch is his previous job involved asking if he could supersize that for you.
Thank God he didn't have low melt point solder terminals or gel filled terminals or he could have set the building on fire.
