Grounding of the distribution box at the end of the cable tray
1 treats the cable assembly as equivalent to Class II equipment, so a single insulation fault cannot raise the tray to a dangerous voltage. If you must earth a tray for functional reasons (static discharge, RFI) . Bonding is the interconnection of metal parts to establish electrical continuity.

In cabling projects, common wiring methods include overhead lines, cables, steel pipes, cable trays, and busbars.
