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.
