What is meant by 'Service Lateral' in electrical terminology?

In electrical terminology, 'Service Lateral' refers specifically to the underground conductors that run from a street main to the service-entrance conductors of a building. This means that the service lateral serves as the direct link between the utility's distribution system and the point of electrical service entry into a structure.

This connection is crucial for delivering power from the utility grid to residential or commercial properties, ensuring that electricity is supplied efficiently and safely. The service lateral is typically buried underground, which provides protection from environmental factors and reduces the risks associated with overhead lines, such as damage from wind or falling trees.

Understanding the definition of a service lateral is important for compliance with the National Electrical Code (NEC) and for ensuring safe and reliable electrical installations.
