That was super helpful. I was assuming from skimming the text description that it was a failed crimp A lot of people wildly under-crimp things, but marine vessels not only have nuanced wire requirements, but more stringent crimping requirements that the field at large frustratingly refuses to adhere to despite ABYC and other codes insisting on it

  > A lot of people wildly under-crimp things The good tools will crimp to the proper pressure and make it obvious when it has happened. Unfortunately the good tools aren't cheap. Even when they are used, some techs will substitute their own ideas of how a crimp should be made when nobody is watching them.

    While the US is still very manual at panel building, Europe is not. So outside of waiting time, I can go from eplan to "send me precrimped and labeled wires that were cut, crimped, and labeled by machine and automatically tested to spec" because this now exists as a service accessible even to random folks. It is not even expensive.

      Can you give an examples of companies that offer this service?

        Sure Onepull does it. Precutwire does it Even dirtypcbs does it Rittal and others who make the processing machines can point you towards tons of folks

    This attitude wherein one thinks they can just spend money and offload responsibility is exactly the problem. Abdicating responsibility to those "good tools" are why shit never gets crimped right. People just crimp away without a care in the world. Don't get me wrong, they're great for speed and when all you're doing it working on brand new stuff that fits perfect. But when you're working on something sketchy you really want the feedback of the older styles of tool that have more direct feedback. They have a place, but you have to know what that place is. See also: "the low level alarm would go off if it was empty"
