Discuss Bonding tray in 18th edition in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net

I'm going to suggest we test it properly to determine as it's not really black and white whether it does need doing or not
Its all down to how different people decipher the reg
In my post before I said it was neither but it can be argued either way
 
Well does it introduce a potential to the location it serves?
Is it in good contact to an outside earth at true earth potential?
I doubt it’s going to be extraneous but then I’m not on site.

Is it an exposed conductive part ie does it form part of the electrical installation or is it mearly a support system for the cables ?

It is a safety precation,it might introduce potential depending on wher and how it is istalled.
I thought by bonding it you are establishing contact with the outside earth

Bonding randomly can create its own hazards
Often when installed the tray supports are fixed to say the metallic structure of the building so are connected to earth that way if the structural frame is bonded by being an extraneous conductive part
