Not if they are in the bathroom (and its RCD protected)
 
No,because I am not working with cable tray,but
My thoughts are,most situations probably not,but
If the specs asked for them to be bonded then bonded they will be,but
I would say that they also need bonding if they enter/exit a building
 
Wouldn't cable tray be an exposed conductive part, assuming you can touch it??

Exposed-Conductive-Part – Conductive part of equipment which can be touched and which is not normally live, but which may become live under fault conditions.

If there was an Insulation resistance fault with a cable on cable tray, there would be potential of it going live, so personally I would bond it, but it could be out of reach??? meaning it can't be touched and doesn't require bonding??

Either way, I would still bond it to be safe.

If it was deemed to be an exposed conductive part then you would earth it not bond it.
 
Tray carrying insulated and sheathed cables would not be an exposed conductive part as the insulation and sheath are deemed to provide the same basic and fault protection as class II equipment 412.2.4.1

You think it is a good idea to bond a tray where it passes from a building, maybe into another.
 
Exactly what I have been reading haha. I didn't even know you can get bare MICC until I read that. Allways thought it was in an orange sheath.

Allways learning, that's what I signed up here for :)
I have installed bare, orange, red, black and white. Pay the manufacturer enough they will probably do you some pink.
