Low Voltage Wiring Methods

Article 300 contains the general requirements for all wiring methods included in the nec except for signaling and communications systems which are covered in chapters 7 and 8.

Low voltage wiring methods.
This wiring is low voltage class 2 typically 1024v dc and provides a pathway for communication of analog or digital signals such as incoming sensor input dataeg light levels occupancy conditionsand outgoing commands.
Thats ok for volt led lights because they have an acceptable voltage range of 8v to 15v.
300 will help you correctly install the wiring methods included in chapter 3.

Which nec wiring methods apply to low voltage wiring.
The problem with this method is that the first fixture gets most of the voltage.
