What wire gauge and circuit breaker should be used for an electric motor drawing 14.5 amps with a 200°C temperature rating?
The appropriate wire gauge and circuit breaker for an electric motor drawing 14.5 amps with a 200°C temperature rating are likely a 10 AWG wire and a 25-amp circuit breaker.
Selection of Wire Gauge and Circuit Breaker
Wire Gauge: The selection of the correct wire gauge for an electric motor drawing 14.5 amps with a 200°C temperature rating is crucial to ensure safe and efficient operation. In this scenario, a 10 AWG wire would be best suited for the application. The 10 AWG wire can carry up to 25 amps, providing an adequate margin for the 14.5 amps drawn by the motor.
Circuit Breaker: To provide protection against overcurrent and ensure the safety of the electrical system, a 25-amp circuit breaker should be used. The circuit breaker will trip and interrupt the circuit in case of an overload, preventing damage to the wiring and reducing the risk of fire.
Explanation of Selection
In the given scenario, the motor draws 14.5 amps of current. To determine the appropriate wire gauge, it is essential to refer to the current-carrying capacity of different wire sizes. The American Wire Gauge (AWG) standard specifies that a 10 AWG wire can safely carry up to 25 amps, making it suitable for the application.
Considering the 200°C temperature rating, the selected wire gauge should be able to withstand elevated temperatures without compromising its performance. By choosing a 10 AWG wire with a 25-amp circuit breaker, the electrical system can effectively meet the current requirements of the motor while maintaining safety and reliability.
Conclusion: The selection of a 10 AWG wire and a 25-amp circuit breaker for an electric motor drawing 14.5 amps with a 200°C temperature rating ensures proper functionality and protection within the electrical system. By choosing the appropriate components based on the current requirements and temperature rating, the system can operate efficiently and securely.
