In general, for field wiring terminals per EN60950:

*       must accept a range of conductors sizes normally expected to be used
*       use screws or nuts - no solder, crimping or special terminal on
conductor (unless a special power cord assembly is being replaced)
*       the screw or nut cannot directly bind against the conductor in order
to prevent damage from rotation
*       a spring or similar to guard against a loose connection
*       sufficient spacing to ensure that a loose wire strand will not short
to the next conductor

variances for internal wire terminals
*       acceptance of a single size wire is sufficient
*       almost any kind of reliable terminal and fastening means may be used
*       a secondary retention method is required if a loose wire would cause
a hazard

        What's the major differences between a terminal suitable for Factory
Wiring and
        one suitable for both Factory Wiring and Field Wiring?
