Electrical conductors that extend from the power source to the point of use are known as ________ runs.

The correct term to describe electrical conductors that extend from the power source to the point of use is "branch" runs. These branch runs refer to the wiring that connects electrical devices or outlets to the main electrical supply, allowing for the distribution of electricity to various parts of a building.

In a typical electrical system, the main service conducts power to the service panel, and from there, branch circuits distribute the power to different locations, such as receptacles, fixtures, and appliances. Understanding this distinction is important for recognizing how electrical systems are organized and how power flow is managed throughout a structure. Branch runs are essential for ensuring that electrical power is delivered safely and effectively to all designated points of use within a building.
