It is not that easy. There are several steps to finding the correct cable for a specific load. It largely depends on the type of cable, the environment to be installed and the supply characteristics. Only a trained licensed electrician or electrical design engineer could do this safely. There's no simple rule of thumb. <><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.
