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.
Stud-mounting the Subpanel
to the Enclosure Back Wall
Stud-mounting a Ground Bus
or Chassis to the Subpanel
Subpanel Welded Stud
Scrape Paint

If the mounting bracket is coated
with a non-conductive material
(anodized or painted), scrape the
material around the mounting hole.
