Under NEC conditions, what type of conductors may be run in open spaces above ceilings and through wall partitions without additional protection?

Explanation:
Low-voltage conductors can be routed through open spaces above ceilings and through wall partitions without extra protection. These circuits (Class 2/3 signaling and control circuits) carry limited voltage and current, so they pose less shock and fire risk, and NEC allows them to run in those spaces as long as they’re not subject to physical damage. If the conductors could be damaged, they'd need protection such as a raceway or conduit. High-voltage, shielding, and grounding paths have different, stricter protection requirements.
