Lighting Transformer - requires earthing?

[simon kennedy]

Hi E.F.
I am replacing 3 lighting transformers in my kitchen.
The existing ones plug into 3 x main sockets which are on the AC mains circuit via a light switch and are earthed.
The replacement transformers have no earth connection - do I need to earth the new transformers? If so, how?
It's a DIY project, any pointers appreciated.
Thanks,

Does the new transformer have a logo, a square within a square? if yes then it's double insulated and doesn't require a cpc.

Hi Murdoch,
The previous transformers were Ikea mains plug transformers, all goosed.
I've attached a grab of the transformer I've bought.

That's a class 2 transformer so doesn't need an earth .....

Thanks Murdoch - I've wired the new transformer up and it works. What do I do with the earth cable that was wired into the mains socket?
Cheers, Simon

Bad idea ........ put a plug on the new transformer and plug it into the existing socket ...............
