What is the minimum required spacing between Class 2 circuit wires and Class 3 circuit wires?

The minimum required spacing between Class 2 circuit wires and Class 3 circuit wires is indeed 2 inches. This requirement is based on safety standards outlined in the National Electrical Code (NEC) and various industry regulations. The purpose of maintaining this spacing is to prevent electromagnetic interference (EMI) that could affect the operation of the circuits, ensuring that both wiring types function correctly without disruptions. By adhering to this spacing requirement, installers contribute to the reliability and performance of the alarm systems while also minimizing the risk of electrical hazards. The specified distance helps maintain clearances between different classes of circuits that may carry varying voltage levels and power, which is critical for the safety of the system as a whole.
