What is the normal distance between manholes for electric utilities?

The normal distance between manholes for electric utilities typically falls around 500 feet. This distance is established to balance accessibility and efficiency in cable management systems. Placing manholes too close together can be unnecessary and inefficient, leading to increased installation and maintenance costs. Conversely, having them too far apart can complicate troubleshooting, repairs, and inspections, prolonging outages and impacting service reliability. Thus, a distance of 500 feet is often standard to ensure that maintenance can be performed effectively without creating excessive infrastructure.

Other distances listed, while they may vary based on specific utility requirements or local regulations, do not represent the generally accepted norm for standard practices in the industry.
