 Just a quick one... does cable tray need to be earthed if all the cables on it are double insulated ?

One of the exceptions, with conditions, is "Protection by the use of double insulation".
I have a job where neutral screen cable runs on a short length of cable tray. It's very easy to bond the tray to the earth bar and I've no problem doing it but I was just wondering if neutral screen is considered "double insulated".
Given that the neutral is an active conductor I'm picking it is not double insulated. Thank you.

Neutral is a Live Conductor. Not active conductor. I sometimes say the wrong thing 😊

I am not so sure on whether a PEN conductor is a live conductor, though.
