dies for 8 awg wire?

[Supervstech]

Yeah 8 is a lot of work compared to 10awg. And 99% of the time absolutely not needed.







With that being said, I used 8AWG wire with 8AWG MC4 connectors with proper 8AWG MC4 crimpers. Solely because I wanted to, it’s way more than my relatively small RV system needs and 10awg would’ve been 100% sufficient.







MC4’s were from Staubli and crimping tools and dies were from Rennsteig (German = $$$).



If you want to do it the correct way for 8AWG you’ll pay 







But I sure do have a unique setup haha







DM me if interested in 8AWG tinned coppYou might wanna rent your tools er PV wire too

You might wanna offer your tools up for rental in the for sale forum. Charge full replacement price as a deposit, then charge rental fee weekly, out of the deposit and return the balance when tools come back undamaged.

You need a set of dies for Helios H4 connectors. I doubt they will work in any crimper body as they require a LOT of pressure to compress the contacts.

If only they sold decent wire crimping dies with them… those hexagon dies make a mess of mc4 crimps…

The terminals the OP shared a link to; shows that it needs a hexagonal crimper.

I believe the dies for those connectors are 4 sided.

Those lugs are for battery cables, not Amphenol solar connector contacts, and are hexagonal.

I do not see where he mentioned solar connectors.
edit: I should have said Amphenol

Really nice crimper. Just not the style needed for the Amphenol contacts.

 

[littleharbor2]

In the opening post. The crimper shown and the connectors are solar connectors.

Your correct they are solar but not Amphenol; the description indicates that you need to use a hexigonal crimper.

Got it. I must've missed that

 

[littleharbor2]

OK, I'm still confused. This is from the mfg. ad itself. Never heard of a Rhombic Jaw but it clearly shows a square, 4 sided die.

 

[HRTKD]

Rhombic (Hexagonal) crimper: you can get the proper crimper for about $25.00 on Amazon.

My die for regular MC4 connectors isn't hexagonal. Regular being for 10 awg size wire.

The "other" cheaper style crimper dies are a ,for lack of a better term, "w" shaped. They fold the two tabs of the connector over and wrap the wire in the folds. These higher quality contactors need an entirely different die. Compare the contacts in my previous post and these cheap contacts.
