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?

[DannyBee]

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
