Wire Ferrules Explained: Why are Ferrules Used and How are Ferrules Crimped

This video first demonstrates what ferrules are and why they're used. It then demonstrates three crimping tools to properly crimp ferrules.

Items demonstrated in this video:

Rotating Head Crimping Tool: FER TOOL ROTO
Gun Type Crimping Tool: FER TOOL 24-10
Gun Type Crimping Tool Kit: FERTOOL28-10KIT
Production Crimping Tool: FER TOOL STRAP

A wire was sticking out of your white wire crimp. Shows why electricians twist the stranded wires so they don't stick out.

Nice demonstration of ferrules and crimping. Do you have any crash course type video to enable layman to do basic things at home...

[gplusgplus]

If you just put on the ferrule and screw it on the terminal screw won't it get pinched as well?

[rakly]

would be nice if they made the insulation heatshrinkable.

Is there an issue with dissimilar metals? Thks

On that first ferrule you crimped with the nice tool, it has a strand hanging out. :-(

Thank you. I bought a crimping tool combo and it came with a box of the regular connectors I've seen all my life. And it included a box of these ferrules, which I had never seen in my 68 years. So, I did what I usually do when needing to know how to use something; I searched YouTube. And thanks to you, I now know what they are used for, and also know that I will NEVER just stick in loose wires in a set-screw terminal again.

Hey Jerry! It's so nice to see you again. I worked with you at the Parks & Recreation Department in Pawnee. So good to see you're doing well.

Thank you for the informative video. I thought these ferrules would come in handy, for small electronics - like R/C quadcopters, where often the wires soldered directly to the board. I can crimp the ferrule, then solder that to the board - instead of having a sloppy wire. Not really a "certified" way to do it, but quadcopter is a hobby - space is limited.

These are late coming into my life but they sure make things convenient.

Thanks for the pointers.  After reviewing several hours of DIY videos (such as yours), I was able to install my tesla gen 2 HWPC. It was a total pain in but still saved me about 1k doing it myself. I'm going back to all the videos that I was able to get some key information and leaving a "thanks" comment.

Thank you, I recently discovered ferrules, this taught me a lot

[Electronzap]

That tool with the strip of ferrules in it is really cool.

[mariuskaizerman]

Almost any brand who offers self-adjusting crimping pliers offers at least two types of crimpers:
1. square (4 point) crimp
2. 6 point crimp

Any reason I should prefer one over the other ?

[Grayback]

These ferrules are very nice.I've used them for car audio applications like compression terminals on amplifiers and distribution blocks.If you don't like the different colors of insulators you can simply use heat shrink to cover them.

[kenibnanak]

If only those tools worked with 6 or 8 gauge braided wire.

Learned something newcthx, I have never seen the belt load. Thats a handy addition I will have to add to my tool box. Great vid, tossed a like in forcyacas well..

[JamieBainbridge]

Good explanation and demonstration of ferrules and how to use them properly, thank you!

[Gruntled]

These are super popular in Russia, used by residential electricians in line voltage applications. A really neat way to attach stranded wire to breaker terminals, busbar terminals, etc.
