Terminals 6014-A (dual 6mm2?)

Featured Replies

I bought these TE6014-A terminals to insert 2 x 6mm2 cables and then crimp.

Two 6mm2 Cu stranded cables are too large for the ferrul.

What am I doing wrong?

Never used these before and not very well made and not very thick metal.20250818_073809.jpg.94b2d051ef5b76cbc244b9125d6682fe.jpg

Yeah, I've had similar issues with "dual" wire thingies, 2 wires of the specified size just don't fit, I think it's just crappy design / manufacturing.

 

Just get the next size up and the job's a good un.

 

These things are very thin by design, crimp them up and they add very little to the overall size.

 

I hope you have the correct ferrule crimping tool, don't just poke the wires in and hope the terminal crushes the ferrule, it won't :whistling:

"I don't want to know why you can't. I want to know how you can!"

A soldering iron and some 60/40 tin lead with flux core will make a much better job.

ON right top of pic , is that the cable? ANd then you have 2 of them to combine in the ferrule?

The wires are very solid for a stranded cable to fit in ferrule. If so even not possible.

Yes ferrules are that thin and are for wrapping stranded cables , but the wiring is way thinner then.

If that is the cable you need to find a complete  other thingie to fit together.

Like the "old fashioned" ones, but there need to be space for 3 of those wires then.

However you have to first put 3 of the cables together, by twisting the wires together.

Annoying job, especially if your wire is like on pic.

Use a terminal block like this

Yes I choose from 2,5 up to 16 mm2, as your wiring is square ? (shown on pic, if im correct)

So all could fit in well in this block. Enough space.

 

Or this one, but is 6mm2 and if you have such a square cable? Be sure to really put in real tight.

Well with all other ones the same, you dont want sparking in the connector.

I would go for the second one, as you have that weird wiring, Square?. DOnt know if it is easy to twist it to round and the able to fit in other ones mentioned.

And you need one wire extra to go to fuse box? Nothing is mentioned about that. Also not what is all about.

 

Be aware power is off ! DONT TRY to cheat on electricity, You can die in jiffy time.   

Fit it properly, take your time. No messing around with electricity.

I used to solder like you suggest, but seems soldering is not the done thing nowadays. 

Something to do with the expansion and contraction of the different metals and corrosion caused by the flux I think.

Seems crimping is the way to go.

Not sure I'm right.

Also difficult when power to that part of the house is disconnected for safety. 🧐😖

Thanks for the reply. 

No that is not the cable on the right in the picture.

The cable is 6mm2 stranded copper cable.

I bought the ferrules for 2 x 6mm2 cable but were too small. As Crossy pointed out he has had this problem before and going to the next double ferrul size above works. He thinks it is a design fault.

So for 2 x 6mm2 cable I should buy 10mm2 ferrules.

Maybe it's OK for solid chore cable, don't know, haven't tried it.

Yes could be, but in my shed I have some separate power feeds. One side 6mm2 and 10mm2 feeds and other side 2.5mm2. So turning off my EV charger feed is only the 6mm2 feed.

 

Google says "Soldering copper wires does not inherently cause deterioration" so if you want to go ahead.

I wouldn't always believe Google.

My friend was coming back from Canada with his Thai wife and neice. He checked with Google if Thais needed a visa for Korea and Google said no. Was just a stopover.

When he got to the airport he couldn't catch the plane as they said Thais need a visa. Google apologised, but he still was out the cost of 3 air tickets.

Also, I know from personal experience that if you don't wash off the solder flux, down the track the joints will all be corroded.

When I was a Telecom trainee I made up a kit form stereo amplifier. (Dick Smith Playmaster I think).

Hadn't used it for years and when I took the case off and had a look there was corrosion everywhere.

Todays electrical codes and industry practices favour crimping for most terminations. Degradation of connections from cold flowing  solder is one of the main reasons the practice is not recommended. 

We always crimped our wires as that would give a more reliable connection when being inserted into a mechanical connection like a terminal block.  

If a construction guy has to terminate 96 wires it is easier to use mechanical crimps than to apply solder to the stranded wire. 

 

If joining only two wires outside a terminal block and time is not of the essence I think soldering is still an option. 

 

Corrosion or deterioration is a historical phenomena  resulting from using acid flux. Looking around me almost everything has soldered connection in them. Acid fluxes are almost a thing of the past.

You also have these ones, You can put wires in and heat from outside. Internal tin melts around wires and at the same time the plastic cover is crimping to make, they say, water tight covering.

You can see a demo on

AH, ok it was together on the pic, so thought maybe that would be the cable.

The ones you have are especially for flexible cables, stranded. What it does , it holds all the strings of the wire together, so you can easily fit in or out connectors.

 

With these ones you can put it under a screw or whatever for a better fix. OR even disconnect easy.

They are thicker, stronger. Lots of them are in your car. But can be used everywhere.

Mind the colors (diameter), red is small in, blue the next one bigger and yellow the biggest.

Good to see the insulating footwear 

Obviously a professional sparky?!

No, it really won't. Google solder creep.
