A breaker is based on the amperage that is drawn by the pump motor load. Find the full load amperage of the motor. The wire fed from the breaker has to be rated at 125% of the motors full load amperage. The breaker for motors have to be over sized, usually 250% of the motors full load amps.

To determine the correct size circuit breaker for a well pump, you should check the manufacturer's recommendations on the pump's label or in the manual. Typically, most well pumps require a 15-amp or 20-amp circuit breaker for residential use. Make sure the breaker is appropriately sized for the pump's power requirements to avoid damage or safety hazards.
A 15-amp circuit breaker is typically used for a well pump that operates on a 120-volt power supply. For well pumps that operate on a 240-volt power supply, a 20-amp circuit breaker is typically used. It's important to check the manufacturer's specifications for the exact amp rating required for your specific well pump.
The current draw of a well pump can vary widely depending on the size and type of pump, as well as the depth and flow rate of the well. It is recommended to check the pump's specifications or consult with a professional to determine the exact amperage.
To run a 120V outlet off a 240V water well breaker, you will need to install a step-down transformer. The transformer will convert the 240V outlet to a 120V outlet, allowing you to power your devices safely. Make sure to follow proper electrical installation procedures and consult a professional if needed.
A 300 watt bulb requires a circuit breaker of at least 2.5 amps. This can be determined by dividing the power (300 watts) by the voltage (120 volts). However, considering normal breaker sizes, a 5 amp breaker would be sufficient for a 300 watt bulb.
