How many conductors are in a 3-conductor service-entrance cable assembly?

In a 3-conductor service-entrance cable assembly, there are indeed three conductors present. Typically, this type of cable includes two hot conductors, which carry current, and one neutral conductor, which returns the current to complete the electrical circuit.

This arrangement is essential for providing a balanced load and is commonly used in residential applications where both 120V and 240V circuits may be required. The inclusion of three conductors enables the system to distribute electrical power effectively while adhering to safety standards.

When dealing with service-entrance cables, it is important to understand that the design of the cable assembly is intended to support the required electrical service, which in this case is characterized by the three conductors that facilitate proper operation of electrical systems.
