Do cable trays need to be bridged or not?
When using galvanized cable trays, bridge bridging can be achieved through the connection of anti loosening nuts or anti loosening washers. For stainless steel and aluminum alloy cable trays,
What are the requirements for the grounding of cable trays specified in
Both ends of the connecting plate must be bridged with a protective bonding conductor (commonly using a copper-core flexible wire with a cross-sectional area of ≥4mm²), and the cross
Practices for grounding and bonding of cable trays
If an EGC cable is installed in or on a cable tray, it should be bonded to each or alternate cable tray sections via grounding clamps (this is not required by the NEC® but it is a desirable practice).
Cable Tray Technical Guide A practical guide to product selection and
In designing supports for a cable tray system, consideration should be given to the loads associated with future cable additions and any additional loading that may be applied to the cable tray system (e.g.,
Practices for grounding and bonding of cable trays
All metallic cable trays shall be grounded as required in Article 250.96 regardless of whether or not the cable tray is being used as an equipment grounding conductor (EGC). The EGC
Earthing or Bonding a Metallic Cable Tray: What the
If you must earth a tray for functional reasons (static discharge, RFI), do it at one end only. Bonding both ends can form a loop, increasing magnetic
NEC Standards for Cable Trays: What Every Installer Needs to Know

Grounding Requirements for Electrical Cables, Cable Trays, and
For galvanized cable troughs, zinc is a good conductor and resistant to oxidation, and the tray''s connecting plates are also galvanized, allowing direct use of the connecting plates as bridging
Does Metallic Cable Tray Require Bonding?
If the tray/ladder is carrying sheathed and/or armoured cables (which it most likely will be) then the nature of that type of cabling suggests that the tray/ladder won''t require earthing as the
Does a Metallic Cable Tray Require Earthing or
Largely the answer to this question is no and therefore normally there is no need to connect bonding or supplementary bonding to the tray.
Earthing or Bonding a Metallic Cable Tray: What the Regs Really Say
If you must earth a tray for functional reasons (static discharge, RFI), do it at one end only. Bonding both ends can form a loop, increasing magnetic coupling and nuisance RCD trips.
