Dear John,
Varistors to Ground (earth) is a very old fashioned way for
designing equipment to withstand transient voltages. A better and
more sophisticated way is to use some better engineering
principles; for example larger clearances/creepages (approx 6 mm)

Hello,
Something to consider. I have no clue as to whether this fits the original
question, but it may be of interest anyway.
We had a situation arise where a two wire(Class II) AC adapter and a

there are some problems with what you wrote in your message yesterday:

Hello Robert,
this is a good question.
I remember to have asked several test laboratories in Germany regarding
this matter.
The product I asked about was a mobile GPS-System with a notebook as
