What is the purpose of a service lateral?

A service lateral is primarily designed to connect the utility power lines to a building's service entry. This connection is critical as it serves as the first point of electrical access for the building, ensuring that power is delivered from the distribution network to the premises. The service lateral consists of underground or overhead conductors and may also include necessary components such as transformers or service pedestals, depending on the specific installation.

This connection plays a vital role in the overall electrical supply system, as it facilitates the transition from external electrical sources to the interior wiring systems of the building. Understanding this difference is crucial in comprehending the overall electrical infrastructure and how electricity is conveyed from generation sources to end-use points within residential or commercial structures.
