What are tap conductors defined as in electrical codes?

Tap conductors are specifically defined as conductors that have overcurrent protection ahead of their point of supply. This means that these conductors are designed to extend the service or feeder conductors to specific loads without needing additional overcurrent protection directly at the point where the tap conductors begin. The requirement for the overcurrent protection ensures that these conductors are safeguarded against overload conditions, thus enhancing safety and reliability in the electrical system.

In terms of code compliance, this definition emphasizes the importance of protecting conductors that supply power to various downstream circuits, especially in commercial or industrial settings where multiple loads may be served from a single source. Properly sizing and protecting tap conductors is crucial in maintaining the integrity of the electrical installation.

The other options, while they may contain some elements of truth about electrical systems, do not accurately capture the definition of tap conductors as outlined in the electrical codes.
