throughout the installation thus preventing a hazardous potential difference occurring between such
parts in the event of a fault.
Connect bonding cable from main earthing point to the bonding point on the bottom of the cabinet with
M6 lug.

Do NOT interconnect bonding busbars in multiple cabinets in multicabinet installation. Connect
