How far should Band 1 and Band 2 circuits be separated by?

The correct distance for the separation of Band 1 and Band 2 circuits is 50 mm. This requirement is established to ensure adequate insulation and to prevent interference between different types of circuits. Band 1 typically refers to low-voltage circuits, while Band 2 pertains to higher voltage circuits. Keeping a separation of 50 mm helps to minimize the risk of arcing, electromagnetic interference, and ensures any accidental contact does not lead to hazardous scenarios.

This specification aligns with standard best practices in electrical installations, where physical separation is crucial for maintaining safety and performance. Proper separation also aids in compliance with regulatory codes and ensures the reliability of the electrical systems by safeguarding against potential faults that may arise from proximity.
