Are there specified rated currents for ordinary instrument cable terminals?

When ordering an on-site junction box, the manufacturer requests information regarding the rated current of the box’s terminals. Are there any regulations regarding this? I haven’t encountered it before

There are regulations: when the current is high, larger terminals must be used; it’s not possible to select terminals if they aren’t provided. If it’s just an I/O terminal cabinet, you can inform the manufacturer that all terminals should have a current capacity of no more than 5A

They are the terminals of the on-site junction box; can they be determined based on the rated current of the cable?

5A DC is fine, except for those powered by AC.
