This is not ordinarily done by formulas, but rather by looking up in electrical code tables. There are already many CR4 threads on this topic that you may search.

Yes. Purchase a copy of your local electrical code. There are several tables that will apply, according to ambient temperature, voltage drop in the conductors, how the conductors are enclosed, how many there are, etc.

Given the information you've supplied, it's not surprising

Study the drawings of each item,check terminal block connections and decide size and the number of cores and then check VD.

Generally 2.5 sq.mm Copper conductor cable would do for control applications.
