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.
• Bond the top and bottom of each subpanel to the cabinet by using
25.4 mm (1.0 in.) by 6.35 mm (0.25 in.) wire braid. As a rule, the wider
and shorter the braid is, the better the bond.
• Scrape the paint from around each fastener to maximize metal-to-metal
contact.
