- Electrical Terminal Service (www.electerm.com) has you covered when it comes to wire ferrules, including bare ferrules, insulated ferrules, twin ferrules, and ferrule crimping tools.
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

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 RUclips. 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.
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 the..... 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.
That tool with the strip of ferrules in it is really cool.
These are late coming into my life but they sure make things convenient.
Thank you, I recently discovered ferrules, this taught me a lot

Very informative video! I was researching plumbing ferrules and came across this and learned something new today. Thank you!
same here
Good explanation and demonstration of ferrules and how to use them properly, thank you!
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.
Nicely explained. Learned something new today! Thank you for posting this video and for the effort taken to make it.

Great Video as Always
Nice demonstration of ferrules and crimping. Do you have any crash course type video to enable layman to do basic things at home...
I was looking for a way to improve the safety of my home built 3D Printers.. and this video was very helpful ... and now I know why I haven't seen Ferrules here in the US.. Thanks! EDIT: Now I need to import one of those Wezag crimping guns :)
I have used ferrules extensively here in the US since 1989. However, I first saw them in Europe and had to search hard to find them here. They cut down our loose wire problems down to almost nothing. They are easily available now.

A wire was sticking out of your white wire crimp. Shows why electricians twist the stranded wires so they don't stick out.
Is there an issue with dissimilar metals? Thks
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.
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..
If you just put on the ferrule and screw it on the terminal screw won't it get pinched as well?
Hello these ferrules kind of terminal lug can i use this in my thhn to the plugin type breaker?
I have a amp/tyco #59500 crimping tool, what die is used to crimp 14-8 non insulated copper ferrules???
Well explained, ty for the video
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.
Hello just want 5o know what kind of wire do you have, do you use thhn stranded wire?
@@pit3835 in Russia they have stuff very similar to THHN, maybe more strands, like lamp cord in the US, but the real problem is that most terminals there are not designed for stranded wire
@@Gruntled2001 Thank you for the information.Here in Philippines ournstandard wire is THHN i thought i can use that terminal lug.
@@pit3835 You still can, not a problem. I do it in my work here in the US.
That belt feeder is pretty neat. Hadn't seen that before.
would be nice if they made the insulation heatshrinkable.
How much is that gun type crimping tool? Price isn't on the site
Most holes to insert wires are round. Is it okay to use a square crimped ferrule in them? Searched the net for a round crimp. Seems it doesn't exist.
Yes it's ok, I put ferrules into round Wago terminal blocks all the time. The run at full rated amperage with no problem.
What are the pull requirements for a ferrule crimp?
No need on solid wire ?
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 ?
+Marius Kaizerman Most users would not really notice a difference. But to get technical:
The square shape crimped wire-end ferrules offer optimal protection against twisting at the contact point.
Hexagonal crimps (6 point) allow for wire insertion in the clamp from any orientation, and hexagonal crimps, with a somewhat rounded crimp form and extremely low maximum diameter, are ideal for confined clamping spaces.
Thank you
Great explanation many thanks :)
I picked up an rs ferrules tool for £10 secondhand,they go for £70 new here in the UK ,I think it will be useful
nice video visited your site
you mention the wires fanning out when pressure is applied to a terminal screw. Does twisting the wires prior to insertion not correct this problem?
Twisting helps, but under pressure, even twisting will not prevent the wires to start to fan. Ferrules solve this problem.
Ferrules are universal all across the world, just not in the US.
It is better not to touch copper with your skin.
What is the name of the last tool used? The belt fed ferrule crimper.
+Grant Gross The tool part number is: FER TOOL STRAP. We have two in stock, available to ship today.
Give us a call if you're interested. 248-549-2233.
Where can I find the specification for the amount of exposed wire from ferrule?
Ive read it is one diameter?
In my company we make it flush

how are they manufactured. I need machine for manufacturing ferrules.

On that first ferrule you crimped with the nice tool, it has a strand hanging out. :-(
Nahh, not a big deal lets cut off the excess wire shall we... :D
Hello from 2018. Also came to the comments section to point out the sloppy crimp with the fancy tool.
Well he didn’t join the strands together he just stripped it left all the strand fanned out
Yep, he gone cause somebody to die 😶
@@johnnyviva9017 That is exactly what ferrules are meant to prevent, strands making contact with other terminals, that should have been noticed or edited out.
Thanks! Can't beat an instructions video with no waste. This method not project applicable.
why not just tin the wire with solder? does the same thing, no?
Not quite, with solder you also get solder creep.
INCC74656I This was meant specifically to replace the heat, the mess and the bother of soldering.
Neat, safe, and no waiting for the iron to warm up.
Try that when you need to land 500 wires in a panel. Ferrules are the way to go.

Will not be too sure of solder in an overcurrent fault situation. Still get the creep/spreading with the screw terminals.
If only those tools worked with 6 or 8 gauge braided wire.

Eyes freaked me out at first :)
