Re: 4/0 Lug / Connector Crimper

What is the practical significance of whether a 1/0 battery lug will support 190lbs--or 900lbs?
Just curious.

Just curious.
The tensile strength can form the basis of a practical test method.

The tensile tests are industry standards for testing crimped connectors. UL has a spec as does the US Military, NASA, SAE and even the ABYC.

The military for example has a minimum tensile load rating per wire size. Then they salt chamber test and vibration test the crimps and test again to make sure they still meet the requirement. Solid gas tight crimps should be unaffected to the minimum tensile rating after salt chamber and vibration testing.

Different specs have different tensile ratings. For example:

UL 486A for 12GA wire is 70 Pounds
Mil-T-7928 for 12GA wire is 110 Pounds
ABYC E-11 for 12GA wire is 35 Pounds

Has anyone used them?

Re: 4/0 Lug / Connector Crimper

Back to crimpers, I have a hydraulic crimper from Harbor Freight came with dies for 2/0 through about AWG 12. I know, cheap Chinese junk, but it works very well. Cost was $59.00 saw it on sale a couple weeks ago for $49.00. I bought the insurance for $10 bucks, if it breaks they hand you another. Anyhow the bottom line is you need to make airtight connections to prevent corrosion, in my opinion.

Sure have. More bulk, not corrosion resistant and they sure donít look professional. Stick with Main Sail he knows his stuff.

BTW Iíve been a boat dealer and service facility for over 40 years and have seen a lot of home brewed fixes and that one pops up a lot.

Did you inquire about the Greenlee die markings with regards to the FTZ markings?

.
Actually, I didn't.
I did read more but at the end of it all, I figure I'll just try them. I needed some 4/0 with 5/16" holes anyway. If the FTZ Lug crimp looks better, I'll buy new 4/0 x 3/8" to replace the Ancor Lugs I have.
If the FTZ Lugs don't crimp any better I'll get further into (it's already begun) a rationalization process which upon successful completion....... Life will be good, perhaps even excellent with the setup I have now. But until then..... I await delivery of my new Lugs ;-)

Cheers,
Extemp.

Re: 4/0 Lug / Connector Crimper

I have many tools but by far this is the best tool for crimping that I own , it comes with die sets that interchange quickly and a O ring repair set:

Hydraulic Wire Crimping Tool

But it doesn't do 4/0.

Re: 4/0 Lug / Connector Crimper

I recently installed a 12v system on my cat which required over 100 crimps, many in 4/0 cable. I used one of these:
NEW 12-TON HYDRAULIC WIRE CABLE LUG TERMINAL CRIMPERS on eBay!

It worked great and still does. The dies are metric and go up to 120mm2.
