3. All this discussion of crimpers is of no use. Crimpers do not give a diecent connection between the lugs and the wire and particularly 4/0 wire.
This is actually one of the more amusing statements I've seen lately, especially as I have crimped LOTS of 4/0 lugs... What factual basis do you have for this statement?
Have you actually ever used a tool designed for the purpose and tried to pull out a wire?
The right crimper, for the right lug, will make an excellent connection, as it is specifically engineered to do by the manufacturer of the lugs or by a third party manufacturer.
For lugs I use an FTZ Industries Correct Crimp crimper. I use it with FTZ industries heavy duty lugs and use the specified dies for crimping the specific terminals (FTZ Lug / Die Specs
). This crimper exerts 10,000 pounds of crimp pressure on the lug and is what FTZ stands behind to crimp their lugs. Never once had any issues over hundreds & hundreds of lugs crimped. My local battery wholesaler who makes tons more battery cables than I do uses the same crimper, day in day out.
The FTZ or the Quick Cable Hexacrimp are excellent tools with the proper sized dies for the heavy duty lugs both sell. Many of the crimpers from HFT and other makers are NOT designed for the cast heavy duty marine type lugs, have the wrong sized dies and can over crimp, pinch and fracture the wire internally.
Feel free to use your swage it tool, I have no doubt that it may make a decent connection, but to say that proper crimp tools do not make a proper connection is simply poor information without any factual basis..
BTW there are only two brands of heavy duty lugs I will even use these days. I use the ones made by Quick Cable and the ones made by FTZ. The Ancor lugs have gone WAY down in quality lately course they never made any lugs to begin with only sourced them from the lowest bidder. Their wire is not even theirs and is made by multiple companies some US and some not.
