Anyone got any recommendations on a through crimp tool. A job I have been to look at the client wants the CU moving to a more convenient location, on the same wall but moving 0.5m to facilitate the kitchen design they have in mind.

Tails to the CU is fine its the rest of the wiring as I said I doubt there is 0.5m of play in the wiring. So would need to extend the cables. Largest size is 10mm T&E.

Was looking at this tool on Amazon:

Ratchet Crimp Tool

To use with these through crimps (covered with heat shrink after and placed into some trunking if I can't fish through to the new location.

Through Crimp

So before I go ahead and buy the tool I thought I would ask on here if anyone has any recommendations. I mentioned using adaptable box, din rail and din rail connectors. But the client wants minimal boxes and would rather some 4x2 trunking to the CU than box, trunking and CU.

Thanks

Carl
 
how about these. L,N.E in 1 unit. once enclosed in trunking, no need for heat shrink.


OK for the smaller stuff. (up to 2.5mm)
 
It’s for a 10mm T&E cable on a 50amp circuit. It needs crimping and junction box isn’t wanted as client wants minimum boxing etc. Wago is no good as highest they do in that type connection is 41A for the push fit. 32A for spring loaded.

so it's uninsulated 10mm crimps with a couple of layers of heat shrink.
 
Yes as per the links in the first post. I just wanted to know if there were any recommendations other than the ones I intended to buy.
My opinion is that that hand ratchet tool you link to won't deliver nearly enough meat for 10mm crimps. More leverage needed IMHO.
With disclaimer that I don't own either of them, but at the budget end of the market I'd have thought that either this hydraulic set:

or this set with a lot more leverage:
Amazon.co.uk - https://www.amazon.co.uk/dp/B07L2S8FWR/ref=sspa_dk_detail_6

would serve you better. Of course others may have better suggestions. I tend to borrow a mates set and really should get a decent crimping tool!

CEW sell a nice SWA brand of crimps for £30


They're similar to the second set
 
Does anyone else find that you need about three hands to use larger size crimpers? Small single handed 0.5-6mm ones are easy but as soon as you've got two lever arms it's a juggling act to keep the crimp and cable in place.

It can be a bit tricky.. but wedging the crimp in the crimpers first helps alot, as does proper length of stripping. I also have a small vice that clamps to various things... so clamping the cable in there can also help.

Yep - just not so useful for getting a lug onto a cable in a DB!

That is why I like the SWA-brand lugs as the tube is slightly flared so when you slightly crimp it won't slide down while you make sure the cable is pushed in with your third hand.
