Is it true that Class 2 circuits must be kept separate from lighting?

Class 2 circuits are designed to ensure a certain level of safety and are typically low voltage wiring used for signals and communications, such as alarm systems, intercoms, and data communication. Keeping Class 2 circuits separate from lighting circuits is essential for several reasons related to safety, electromagnetic interference, and regulatory compliance.

By maintaining separation between Class 2 circuits and lighting circuits, the risk of potential electrical hazards, such as short circuits and overloads, is minimized. Additionally, lighting circuits can generate electromagnetic interference which could disrupt the operation of sensitive equipment connected to Class 2 circuits. This separation aligns with the National Electrical Code (NEC) guidelines, which provide requirements for the installation of various types of electrical systems to promote safety and reliability.

The incorrect alternatives suggest potential conditions under which separation may not be necessary, but the standard practice and regulatory requirements favor maintaining separation universally to ensure safety and proper function.
