What type of circuit is commonly used for street lighting?

The type of circuit commonly used for street lighting is a multiple circuit. This configuration allows several fixtures to be connected in parallel, ensuring that if one light goes out, the others remain operational. The parallel arrangement also provides a consistent voltage to each lighting fixture, which is crucial for maintaining uniform illumination across the street.

In addition to providing reliability, multiple circuits allow for easier maintenance and management. If there’s a need to replace a fixture or make repairs, the rest of the lights can continue functioning without interruption, enhancing safety and visibility in public areas.

While single circuits can power one light at a time, they do not offer the reliability and flexibility needed for street lighting systems. Series circuits are not practical for street lighting since they would cause all lights to fail if one goes out, as the current would be interrupted. Hybrid circuits, combining series and parallel elements, are less common for street lighting applications where consistent functionality and easy maintenance are priorities.
