Think about this:
What happens when a motor is pulling too much power? The speed contol gets hot. Then the breaker trips. Then power is cut to the speed control. Power is also cut to the fan of that speed control. The speed control is still hot. It now has no fan to cool it.

This is why we wired all our fans to one circuit directly to a separate 20A fuse. When a breaker trips, the speed control is usually hot as well from the motor drawing a lot of power. What the speed control needs least at that time is for the fan to stop. Keep em going and keep Victor cool like he should be.
