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 2 inches. This requirement is based on electrical safety standards that aim to prevent interference between different classes of circuits. Class 2 circuits are typically used for power-limited signaling and control functions, while Class 3 circuits may be used for power-limited loads but can include different voltage and current characteristics.

Maintaining this specific spacing helps ensure that there is minimal risk of accidental short circuits or crosstalk between the two classes, which could otherwise lead to malfunction of alarm systems or increased fire hazards. Adhering to this spacing also contributes to the overall reliability and safety of the wiring installation, ensuring compliance with electrical codes and standards that govern alarm systems in Utah.
