To answer this question the motor voltage is needed.
Find the amperage that your pump motor operates on (should be on the motor nameplate) and multiply it by the voltage that the motor is connected to (120 or 240 volts). This will give you the wattage of the motor. It is usage of watts that the utility company bills you on. Find from your utility bill what you are charged per kilowatt hour. Take your pump wattage, times the amount of time that the pump runs, times the kilowatt rate you are charged by the utility company and the result will be how much it costs you to run the pump motor.
To answer this question the voltage and amperage of the motor must be given.
It is quite possible the blower motor is drawing too much amperage. This is caused by a motor that is wearing out and starting to drag slightly drawing more amps to keep the motor turning. It can also have dirty wire connections at motor causing high amperage draw...
a relay that detects the amperage the motor is drawing when the motor dwaws too much to drops out the coil voltage to shut down motor and prevent damage
The blower motor resistor is defective. They go bad when the blower motor pulls to much amperage.

Breakers ensure that when too much amperage is being drawn through the circuit the power is shut off. Excessive amperage creates heat. Without a breaker that heat buildup could lead to fire.
More than likely it's a bad fan motor drawing too much amperage.
Circuits are limited for a few reasons firstly because certain size wiring can only handle so much voltage and amperage before it could fail secondly wiring heats up when more amperage is drawn through it which can create fires or burning out of the circuit most appliances draw set amount of current and amperage if you have a low amperage appliance Eg pool pump drawing 4 amps and the windings start to fail the motor can start drawing excessive amperage creating a hazard, if you had a large circuit it may never trip the breaker indicating a fault with the appliance which can cause catastrophic failure.
Most likely it is a fan motor that is pulling too much amperage. I'd start with the fan motor and/or the fan motor resistor.
Need to know the voltage of the motor. Use this formula, I = W/E, Amps = Watts/Volts. Once you have the amperage then ask, what size wire is needed for (your amperage) at (your voltage).
