Re: No more racheting wire crimper for me.

Thinwater: I am not sure what you are throwing in the trash but since you posted immediately after my post I am assuming you are making a small mistake in identification. The Klein tool is a copy of the Thomas and Betts, though if you compare the fine points of construction and the strength of the handles the T&B is superior. The only way to tell them apart at a glance is one has black and red handles and on the other both are red. Not sure where you get the idea that the handles are short, You thinking of something else?

You are right that a perfectly calibrated automatic crimper is the best. Note that I say calibrated. The big boys that do production have the crimper calibrated to a particular wire size, insulation type and probably brand. The same for the connector and that gives a near perfect repeatable crimp. Change any of the variables and the tool just blindly goes on making, potentially at least, less that ideal connections. The simple hand ratchet crimper using a variety of wire and brands of connector in no way compares to that factory standard.

A simple hand tool like the T&B or the Klein will make excellent connections in the hands of a good electrician.

When all my connections start failing I will certainly let you know.

My apologies. It was directed at a much cheaper combination tool 2 posts farther up.

Re: No more racheting wire crimper for me.

Best post here...

Thanks for the laugh Mark!

This post confuses me a bit. Ratcheting crimpers are designed to provide the correct compression that ensures a proper crimp before they release. If you haven't reached that point, the crimp is not good.

I wouldn't call that crap.

Are you saying you prefer to base your crimps only on the pressure you choose to apply?

Re: No more racheting wire crimper for me.

If folks would read the instructions....

a. Ratchet crimpers have a release lever. Simple.
b. The crimper must be calibrated for the wire/fitting combination before use (wire should break before pulling out). Takes only a minute.

Perfect, lifetime job, every time.

There were no instructions. It was the first time I had used them. I worked out their correct use whilst dangling

That always speeds the learning process! Necessity and all of that.

I will say that ratchet crimpers encourage the user to stay with one brand of wire and fittings.

A good ratcheting crimper can be purchased for around $40.

For around $15 you can...LOL.

Re: No more racheting wire crimper for me.

that is my point. sometimes, due to the circumstances of the install or repair, its too difficult to use the racheting crimper and to get the best crimp you use something else.

Re: No more racheting wire crimper for me.

Why pay $15 when these are laying all over the place?



Same quality crimp

Reminds me of a test lab job I had once.... The item was cables utilized for an "electric chair" .... Yep... the capital punishment kind....

We weren't requested to test current passing capabilities....

Only... Pull out strength of the terminals...

Sounds like a good job for an apprentice. The one that showed up late.
