When converting an underground cable to an overhead line, what is required?

When converting an underground cable to an overhead line, a riser and pothead are essential components required for the transition. The riser allows the cable to change direction vertically from underground to overhead, ensuring that the cable is properly secured and supported as it rises.

The pothead serves as a termination point for the underground cable at the location where it will connect to the overhead line. It provides a weatherproof enclosure that protects the cable's terminations and electrical connections from moisture, debris, and mechanical stress. This is crucial for maintaining the integrity and safety of the electrical system, which is exposed to environmental conditions once transitioned to overhead.

In contrast, while a conductor and junction box, insulator and transformer, or cable tie and clamp may play roles in electrical systems, they do not specifically address the unique requirements and functions involved in converting an underground cable to an overhead line transition. Each of these options may pertain to other installations or applications but lacks the crucial elements that the riser and pothead provide in this particular scenario.
