I am shopping for big amps connectors for my solar/battery system. Can you guys tell me the best way to waste my money to use/connect/terminate those angry copper toys? Knipex again? EDIT, on my way.... |

yuckyputz. A few dollars more gets you these hydraulic crimpers: https://www.amazon.com/ABN-Hydraulic-Crimper-Crimping-Terminal/dp/B08DP43M5B This variant is on sale; you might also want to look at the heavier-duty model on the same page: https://www.amazon.com/UTZIKO-Electrical-Tool-12awg-00awg-Crimping/dp/B09Y8MKPG3/ I've used similar for wire rope; they're just nipply. mnem :-/O |

Interesting the first comment.... --- Quote ---I like to solder all my lugs on for an even better connection. And in the example at the end where you cut through the 4 - 0 lug, you chose a location where it had not been crimped thereby showing an uncrimped gap inside. Not a nice demonstration. Solder has always been superior to crimp, throughout the history of cable lug use. Not sure where you went to school but we actually tested crimped vs soldered connections for resistance and noticed failures in current draw tests. The solder, when done correctly always produced better results than crimps when done correctly. In most applications, either will suffice. However, for pure results solder wins. Silver based solder is 5% more conductive than copper (copper 100%, silver 105% using copper as the standard conductor). Heating wire tends to distort the insulator so care must be used. I like to use a wet rag to cover the insulation near the end or an cooling paste which is available from most HVAC wholesalers. Silver requires a bit more heat than propane, though so most opt for the crimp. We're talking about the purest method here...in real life and in most situations the crimp will suffice. Its important to know the composition of the lug being used as well. Some are made of aluminum while some are copper and other's copper with a tinned coating. Best to choose one with copper, either bare or tinned, since aluminum tends to oxidize over time which creates friction within the lug. I've seen 'em glowing red like a toaster element from bad connection. I got about 50 years experience in this subject. --- End quote --- |
