Ferrule crimping - An easy way to improve reliability of electrical connections.

Рет қаралды 249,002

Күн бұрын

Crimping a bootlace ferrule to the end of a stranded conductor or fine wire is an easy way to improve the reliability of an electrical connection. In this video, we explore what can happen to conductors when you don't use a ferrule crimp.
Using a ferrule can speed up electrical installations, ensure consistency across connectors. They make life easier for electricians performing maintenance activities in the future by making it easy to remove and replace wires without damaging the conductor or retwisting strands together.
To demonstrate ferrules in this electrical tutorial we are using a Wiha ratchet ferrule crimping tool. This tool can cope with conductors from 0.08mm2 up to 16mm2. A unique feature of the Wiha crimp tool is the guide plate which is sized to allow easy handling of smaller crimp ferrules.
Comments always welcome.

In allot of industrial sites I've worked on (oil and gas) the use of ferrules on all connections, ELV or LV is mandated in panels, junction boxes or end devices. They are a good job and don't really take any longer once you get used to using them. They are especially good for connections that get removed now and then for testing or alterations, I think this is the main advantage in using them, you can terminate them multiple times and they still provide a perfect connection, twisted strands are only good for one or two terminations before they need to be restriped and twisted up again and the wire is getting shorter every time you do that!

I came across this video while researching the use of ferrules; as I've always been uncomfortable with the way stranded wire gets chewed up. I didn't know you could get one to connect two wires together. Apart from protecting the wires, it solves the age-old problem of one wire slipping out when you are trying to put two into one connection. Love the video.

What a brilliant video. I don't know if it's just me, but this is the first video I've seen advocating the the use of ferrules in a domestic situation, inline with industrial standards where reliability is perhaps more important. Very well done sir, a point very well made! Perhaps I could add that the ferrules you are using have plastic end bits that are quite bulky, which is fine for one core, one termination. Where several wires are entering one termination though I find that plain ferrules are handier, and three or more cores can be inserted. I appreciate double type ferrules as you show are available but its not always the best solution. Once again many thanks for the great video.

Awesome video! I'm an auto electrician by trade and I work out in rural areas, and there is a tool at the start of the video I have not seen before, but been thinking about making! it's that handy wire roll holder on the right side of the screen in the first 30 seconds of the video. I work in a workshop, and I have been lucky enough that the bollards used to keep cars in the workshop at night are a smaller diameter than the inside of my rolls of wire that I work with, however I don't always have access to these bollards due to where the cars are positioned sometimes, and due to being in a workshop with other people. Also, these bollards require a hole in solid ground with a steel pipe inserted into concrete in order to work, and that setup just isn't portable for the times I am having to work outside of the workshop and on somebody's farm. I don't suppose you would have a link to where someone could purchase this product in Australia?

Great video! We use ferrules all time using the single wire connectors similar to what is showed at 7:33. Looking at your example, I can see some of the barrel of the ferrule poking out not allowing the shoulder of the ferrule to butt up against the connector. I like to cut off the end of the ferrule so that none of the barrel shows and the shoulder (the plastic part) is butted up against the connector (if that makes sense). My question is if that is good practice or not to cut the end off? or if you know what the standard is. Any info would be appreciated.

Thanks for the video. I have been using ferrules for several years on all flexible cores. Something to bare in mind, they don't always work. I have had experience with terminating 1mm flex into a spur with a ferrule and they fall out, some spurs terminals can be too big for a small ferrule like 1mm or 0.75mm. So I have had to cut the ferrule off many times, twist and fold over to get my decent connection. This doesn't happen in all spurs depends on the branding, just double check them before screwing back.

Ferrules are incredible and underused. See them quite often in commercial BMS installations and they make a panel look so tidy and the terminations are much more effective than twisted strands, which often seem to break when the screw has been overtightened. Also, lots of panels use push fit connections, try pushing a twisted stranded cable into a push fit connector:/

Thanks for the video. At first, this topic is a bit of a minefield with such enormous variation in a number of variables for the process of crimping. May be doing a detailed look at all the different types would be helpful such as self adjustable square vs. hexagonal crimping tools etc...Also, the variation in quality of these tools is enormous from cheap chinese designs up to what I could see as one of the best manufacturers being Weidmuller. I would imagine there is also quite a variation in quality due to the standard of ferrules themselves. What could have given clarity to this video would have been taking measurements on a voltmeter to prove the ferrule was a better connection in comparison to the bare wire... may be one for the future! : )

@_--_--_ 4 жыл бұрын

Problem beeing you would probably not see a difference when measuring resistance, even if only one strand of the bunch was connected, as the higher resistance path would be very short. However you would still have that high resistance spot, which would create a hotspot at higher currents. Quite misleading if you are measuring resistance and thought its alright, while in fact it isnt. Though you could pass a few amps through it and measure voltage drop, that would work better.

Definitely a good idea for the typical 7 copper core house wiring. The problem is that electricians have a bad habit of leaving barely any slack inside fittings and screws in the terminals nick the cores, so that when replacing a fitting invariably some of the cores snap while trying to insert or screw the wire into the new fitting. Once the wire is stripped back a bit to expose intact cores the wire is so short it is almost impossible to get it inserted with the fitting out of the wall. A ferrule protecting the cores would hopefully solve this.

@Candisa 3 жыл бұрын

"The problem is that electricians have a bad habit of leaving barely any slack inside fittings..." That's called bad practice, or a plasterer who cut 'those annoying unnecessary long cables' between first and second fixing. Good electricians leave enough slack on their cable to reach the end of the fitting opposite of where the cable enters and then bend back to the terminal, or even a bit more than that.

Great video giving examples. Had the debate with our qs when I put on an EICR that neutral fly leads on rcbos had been shortened and only twisted in terminal. I gave it a c2 and said its a regulation to use them. 526.9.1 he said that must be a new reg so I continued to show him it in the 17th and in the 16th. But yes all who don't use them when using screw terminals should really change as soon as its pointed out to them. However the guys on site will call it a specialist tool and expect company to supply it. That said I have 4 in van 1. 25,35,50. 2. 6,10,16 3. 0.5-6 and 4. 0.25-10.

When shortening rcbo leads i almost only ever use a 4mm grey bootlace ferrule. Now as the size of the neutral for the 6A and 32A differ i should probably be using a blue 2.5mm for the 6A but i find the larger grey gets crimped very tightly although its not a perfectly square crimp. The screw terminations torqued to 2Nm further compress and tighten the ferrule. The only time id be concerned with getting a compressed slightly distorted ferrule is if it were being used in a square clamp and the square edge was required for contact. Anyone disagree?

In india we see these as valueless but it is good compare to old method. We use old method since long. Nothing problem in electrical disruption.

one big issue tho - someone thinks crimping is a good idea so they choose a crimp, its slightly too big, gets a poor crimp, the screw grips the crimp but the wires fall out of the crimp. very important to get the right crimp for the cable csa

Ferrules should not be used to make a bad idea better, they are not the "Answer" as you say to good workmanship.

@brucerobson8767 Жыл бұрын

You use the terms ‘nice and tight’ and “firmly and securely” for tightening the screws on ferrule. I’ve invested in a torque screw driver, what torque do I use?

Never saw a sixteen sided crimping tool, I have a four sided in the same style and an old school one with the two faces pressing into each other. Would you say one with more pressing sides (basically making the surface more round I guess?) Is better than one with less pressed sides like a two ore four sided one? Greetings from Germany ✌

Depends upon the type of terminal - hexagon slightly better for round holes. Square for square.

@@efixx so having both around might be a good idea. Thanks. I suppose the hexagon one is more expensive?

The correct answer is you should use whatever the electrical code specifies in the locality where you are! Having done high-tech installations in over 20 countries, I can tell you what is “required” in one place is specifically disallowed in another. Interestingly, it’s in the UK where I have seen these ferrules disallowed, because the wire can actually slip out of them, even when you think you’ve got a great, snug connection. All is not always what it seems, so go by the book, and never assume the way you learned, or the way you think is best is the way to do it wherever you are.

When it slips out it wasn't crimped properly. If you make a good crimp connection and try to pull it off the wire, the copper wire itself will fail before the crimped connection. I've seen guys trying to crimp ferrules with their combination pliers because they hadn't the proper crimping tool. No wonder that such crimps will fail...

The issue that I have had is that a cable that will fit into a conection with out . Some times will no longer fit into the connection after you have crimped a ferule on to it .

@@hotrex7779 It depends also on the shape of the crimp, the square shaped crimps don't make so much trouble. It also depends on the type of connector and it's current rating. You can't put a 1.5mm² with a ferrule in a 10A terminal, but in a 16A one they'll fit.

youve seen these disallowed in the uk. what industry was that in. think youll find many panel companies use these. its not hard to use the right crimping tool for the job. plus dont put a 2.5 ferral on a 1mm cable.

Hi I was looking to get a crimper. Would the sleeves you crimp on be OK for a 3 pin plug. Thank you.

Absolutely

@unclefatbloke687 Жыл бұрын

it would be better to use UNinsulated ferrules though, because the plastic sleeve will cause the bend radius to be too large for the tight corners in the plug! Also the screw clamps are not very deep, so you might need to snip off a few mm of the ferrule after crimping.

@Splattertube 11 ай бұрын

Maybe a silly question, but I run into equipment that spec "use copper conductors only." Does the ferrule still satisfy this specification? I saw another comment here regarding checking and comparing continuity of bare vs. ferruled conductors.

@efixx 11 ай бұрын

When you see “copper” only it really means don’t use aluminium as they require special precautions. Ferrules are made of tinned copper so should be an issue. You can find white papers on the web comparing long term performance of bare copper vs ferruled conductors - ferrules win
