Conductor count determines how many power, control, or communication circuits a linear lighting installation can carry, with two-conductor cable suited to simpler connections and six-conductor cable supporting more complex lighting systems. Wire gauge affects conductor capacity and voltage drop over the run, while shielded two-conductor cable can help support RS-485 or DMX communication, so select the gauge, conductor count, and shielding based on the system requirements and cable distance.

Use shielded control wire when an RS-485 or DMX linear lighting system specifies it, particularly on runs routed near power wiring, motors, or other potential sources of electrical interference. The shield and drain help reduce unwanted noise on the control signal, while the conductor count and gauge should match the lighting system’s requirements.

Linear lighting control wire in this category includes low-voltage options with CM and CL3 ratings, while some specialty cables also carry FT4 and UL Listed designations for fixed installation. Temperature specifications vary by cable, with listed operating ranges from -20°C to 75°C, and some options intended for use below 80 volts.

Plan separate low-voltage runs for power, control, and automation connections, choosing the conductor count and gauge required by the lighting system and using shielded wire for RS-485 or DMX control signals when specified. Keep runs accessible, label both ends, allow service slack, and route signal wiring separately from higher-voltage wiring to support cleaner installation and troubleshooting.
