    Should this fitting be bonded to earth

    I have had these lights installed by a contractor whose work is normally very good. He has not connected the earth in each fitting as there is a class 2 sticker on the metal back plate.

    Smart Switch without Earth Terminal

    Hi, I've bought a "yagusmart" smart switch from Amazon and it has no earth terminal. Although there are no metal facing parts I would think the device itself still needs an earth?

The bonding looks like 6mm^2. And the connection point looks like that's the max it will take. As I understand...
