What term describes wiring installed inside a building for power and communications?

Explanation:
Premises wiring is the standard term for wiring installed inside a building that carries electrical power and communications signals. It defines the infrastructure within the property's boundaries—from the service equipment to outlets, telecom jacks, and network cables—distinguishing it from wiring outside the building (outside plant). This makes it the most precise and widely accepted phrase for the scenario described. Terms like indoor wiring or internal wiring are vague, and in-building cabling, while understandable, isn’t the conventional terminology used in codes and industry practice.
