A dedicated branch circuit means power is wired to feed only one outlet or piece of equipment, using its own hot (phase), neutral, and grounding conductors, without sharing those conductors with other loads. This arrangement ensures the device gets clean, stable power and that protective devices respond correctly to faults without interference from other circuits. In a telecom room context, this helps maintain reliable operation of critical equipment and reduces electrical noise and nuisance trips.

The statement that describes a circuit servicing only a single outlet with its own dedicated phase, neutral, and ground conductors matches this idea exactly. The other scenarios describe sharing neutrals or grounds, or lacking a grounding path, or serving multiple outlets, which do not meet the definition of a dedicated branch circuit.
