Ferrule Connectors

RWL posted:

I purchased one of these ferrule connector kits, and the crimper works very well, but my concern is that the ferrules are supposedly NOT tinned copper.

Would they still be good to use, or should I just get the correct, tinned copper, ferrules for the sizes that I plan to use?

Thanks for all comments,
Roger

 

Any comments at all would be appreciated.

From the listing:

Not sure what you're after but "copper alloy" should work for any electrical connections. I think I'd go ahead and use them.

Thanks.

Would you mind sharing where you found those specifications?
I have looked and looked and looked.

Scroll down on the page.

Amazon... The descriptions are always there.

Then on bottom. Are comments

RWL: As Riki points out, they are from the Amazon description that you linked in your post. They appear before the comments on the page. It's sometimes hard to find things on these pages because of so many links and other items that Amazon is trying to sell.

Thanks guys,

I looked and looked, but will look again.

OK, I found it. All the way down at the bottom.
I just didn't look far enough

So the consensus seems to be that these would in fact be safe to use, regarding durability, corrosion, etc.
Correct?

Thanks again,

RWL: There is no reason that I can think of that these will not work as well as anything else for connectors.

The emphasis in the Amazon listing is all about how great the crimp tool is and the connectors are hardly mentioned at all. The majority of what you spent went toward the tool and not the connectors. If you would rather use a different connector, try to get some that are compatible with this tool.

I've never seen a tool quite like that.

Yea, the ones that I see in all of the videos on ferrules, look like 5 or even 6 jaw crimpers.
This tool does creates a square shape, and it does have serrations that introduce deep detents in the 4 sides.

Mine does, so the answers are yes, and yes.

I don't get it. You stick two or more wires in the plastic-covered end, crimp on the metal end, and then you have exposed metal?

And then you can't use it for ring or spade terminals, you need to buy another crimping tool?

I personally use Wago brand Lever Nuts there are other brands. These are designed for house AC wiring but you can "re-purpose". A quick search on Amazon came up with a newer version with a bigger lever than the one I use. The biggest downsides are cost and size, upsides are you can re-use the wire and the connector.

Another option of which I use at work is DIN rails and DIN rail blocks. Kinda like Legos for electrical.

If you're going to use crimp-ons, why use these rather than the normal fully-insulated connectors.  A marine air conditioning manufacturer told me that one of their biggest problems is crimps not properly done.  I have had experience with crimped connections buring up after several days of contuous compressor operation.  Since then I switched to Ideal connectors for heavy loads (too expensive for model RR use).  IFor regular crimp-ons, I bought a couple of double crimp ratcheting tools

I am using ferrule connectors with a ferrule crimp tool.

The crimped end will be inserted into the Eruo Style terminal blocks, rather than inserting the stranded wire, which can fray, and not give full contact, and possibly leave a strand hanging out to create a short.
