How To Crimp A Wire Ferrule

How To Crimp A Wire Ferrule

A wire ferrule is a simple way to finish off the end of stranded copper wire and prepare it to be used in a screw terminal like you’d find on a charge controller.

Crimping a wire ferrule onto a stranded wire can turn a ugly, high resistance messy wire end into a neat and tidy, low resistance professionally finished wire.

I noticed you use square ferrules vs hex. Do you use square ferrules in round holes? I think the solar panel disconnect you recommend has round holes. It seems like a square ferrule in a round hole would not have many contact points between the ferrule and the hole?

The crimping tools for 6/0 wire are either not available or very long lead times. Searching for just that reveals nothing. Guess we won't be using wire ferrules.
