They are "double insulated" & do not require an earth.
If you are concerned you could use an "RCD" for extra protection, but they are just that "extra protection" - not the be all & end all that some think.

The first thing that goes wrong usually is a loud humming but even then they still work. I know cause i've had 2 do that to me. But I am going to change soon to panel mount gaugemasters. I already have a dual feedback controller just need the transformer now.

That will be the mains transformer laminations loose or the fixings that hold the transformer to the case.
