If no barriers are present, what is the minimum spacing required for Class 2 and Class 3 wires?

The minimum spacing required for Class 2 and Class 3 wires being 2 inches is based on safety standards and best practices for electrical installations. This specific spacing ensures that there is enough separation to minimize the risk of electrical interference, shorts, or other issues that might arise from wires being too close together. By maintaining a minimum distance of 2 inches, it helps ensure that these wires can operate safely and effectively without the risk of cross-talk or signal degradation.

In addition, this spacing guideline is important for providing adequate heat dissipation and reducing the likelihood of physical damage or accidental contact between the wires. Compliance with these standards is critical for the overall integrity of the alarm system, which relies on these wires for proper functionality.

Understanding this spacing requirement is vital for anyone involved in installing or maintaining burglar alarm systems as it enhances system reliability and safety, aligning with the regulations in the National Electrical Code (NEC) and other industry standards.
