Service laterals are the electrical conductors that provide the connection from the utility's distribution system to a property’s electrical system. The configuration of these service laterals can often be determined by their method of installation.

When service laterals are installed underground, they typically utilize specific conduits and cables designed for such applications, which have different configurations compared to overhead lines. Underground installations are often characterized by their ability to protect against weather-related issues and physical damage, leading to a more standardized installation method, which directly indicates the configuration. This underground configuration also involves considerations such as depth, type of cable used, and any required markings or conduits, which are essential for safety and codes.

While height above ground, visible connections, and flexibility of wires can provide some information about electrical systems, they do not necessarily indicate the specific configuration of service laterals in a definitive manner, unlike the clear criteria established by underground installations. Thus, the proper identification of service lateral configuration is best represented through the context of how they are installed, reinforcing the importance of recognizing the significance of underground installation in this context.
