Victor connect to 30 A instead of 40 A

For smaller motors like PG71/188, usually or 30 amp unless its a continuous-usage motor (for example some conveyors) because of the heat produced in the wiring. Window motors usually 20 amp, Mini CIM either 30 or 40, Van Door/Snow Blower 30 amp.

Moral of the story, determine the power draw based on your motors, not speed controllers. I recommend checking the stall current draw for each motor (those specs are widely available) and judge accordingly.

This is not quite right.

When choosing a breaker, choose it by the wire gauge attached to that breaker as breakers and fuses only protect the wiring.

Now to go further, you choose your wire gauge and drive circuit(victor, talon, spike, etc.) by the load (motor, solenoid, etc.) on the wire.
