Recommended Bonding Practices for Painted Panels

Bonding Multiple Subpanels

Bonding multiple subpanels creates a common low impedance exit path for
the high frequency energy inside the cabinet. Subpanels that are not bonded
together may not share a common low impedance path. This difference in
impedance may affect networks and other devices that span multiple panels.
