> 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.
