WebNEC 300.11 (C) (2) allows strapping a low voltage Class 2 cable to the outside of a raceway only if the raceway contains conductors that are also associated with the low voltage installation. Below is a sample of NFPA 731. For the complete section, see the actual NFPA 731 text at NFPA.ORG. WebFor more advanced functionality and flexibility, dedicated control wiring may be needed. This wiring is low voltage (Class 2, typically 10–24V DC) and provides a pathway for communication of analog or digital signals, such as incoming sensor input data—e.g., light levels, occupancy conditions—and outgoing commands.
