Love how he says to not use traditional wire strippers, but every demonstration is made using them.
Tip 3: yellow-green wire should always be a little longer than L and N, in case if the plug is pulled hard, the PE wire will pull out as the last one.
Another tip for your universal wire stripper: When stripping multistrand wire, before removing the stripped sheathing, use it to twist the strands. You'll get a far more universal and tighter twist that way.
TIP 4: Knots that can tighten will result in the perpendicular crossings trying to sheer through one another while strain is also being applied. If the knot is just snug and then soldered this tip is useful. Heat shrink wrap won't prevent the sheer and strain forces.
a tip for the replacement plug is to leave the ground a little bit longer than the other 2 wires, this means if the strain relief (clamp) on the back fails then the last one to pull out is the ground tis can be commonly seen on Type G Plugs, the brown is always shortest, followed by the blue then the green is the longest so if the wire is pulled out of the plug the Live disconnects first, followed by the neutral then finally the CPC/Earth/ground is last.
All of you guys saw this before I did, and I have to say that you picked this guy apart very well. As one of you said, "a little knowledge can be VERY dangerous". Good job people!
If you twist the wires together as is implied in NEC Article 110.14(B) then the wire nut simply holds them and insulates the exposed wire. The twisting is specifically for soldering or brazing but the idea of a twist on connector is basically the same and why the master electricians I know pre twist the wires before installing a wire nut. Positive connection is achieved prior to installing the wire nut, no guessing if the wire nut created the connection. While Wagos are good it is worth noting that articles I have read indicate they have higher resistance than wire nuts. Not usually a problem but the user should be aware.
The reason to never give up the old wire stripper design is not all insulation behaves with "self adjusting" types as shown. Certain marine style cables are the main offenders. I have run across thermosetting insulation [I forget the exact type] that gets down into the strands which even defy normal wire strippers: a pocketknife or boxcutter was the only way to prepare wire ends, by shaving down wire insulation at a 30 to 45 degree angle, then cleaning remainder out from between the strands before terminating.
Tip #5: Don't use UL Listed connectors, instead use Chinese counterfeit WAGO connectors that aren't certified by any safety agency. Tip #4: Just don't.
I've used them my entire career as an electrician and I've never, ever had a problem with a good pair from a reputable manufacturer such as Klein.
Master tip when using ANY wire stripper on stranded wire. Do not remove the insulation all the way immediately. Use the bit of insulation to twist the wires and then remove it the rest of the way, much neater and easier on the fingers if you do a lot of them... all day long...
Wow. This guy has as much not-so-good advice as he does good. A mixed bag of best practices. Better call an electrician.
40 years experience for me and I agree that some people know just enough to be VERY DANGEROUS! ⚠️
Most of us, as electricians, we'll find this somewhat entertaining and scary. In addition to that, most of us will work with voltages and not signals.
One trick that was missed and also works great with universal wire stripping with stranded wire is that, do not pull the detached piece of sheeting straight out with your fingers. Twist it out, rolling the loose tube while pulling it out. It makes perfect and really tight twist on the wire that is much better than you can do with your bare finder.
I love 1:52 where he starts using the exact tool that the thumbnail and intro are saying no one needs 😂
I have a pair of those automatic wire strippers. I found them to be way more work than the manual ones. You need to constantly adjust the dial on them, they pinch the insulation short of the stripped part (sometimes pinching all the way through), and they usually require multiple attempts to get the tension just right. I switched back to regular manual wire strippers.
I had a pair of universal wire strippers like the ones shown. When I was dealing with some short wires sticking out of a wall receptacle, they were no good for stripping those wires. I had to buy a pair that worked on the same principle, but stripped the wires from the end.
I like Wago’s 221 and 222’s. Also I have switched my preferences to 3M wire nuts. Especially the tan/red ones. They work for most connected circuits in home construction.
Those large universal strippers don’t always work in 12v applications where space is limited. Also, if you do this kind of work long enough, you can eyeball the gauge wire you are working with to a t.
Overall, fun video and some good hints.
