Peter,
You are correct regarding the leakage issue.
MOV's will break down after time which may increase the product leakage
current.
MOV's are allowed to be used from line to earth when placed in series with a
gas discharge tube that meets the requirements for basic insulation.
I believe there are MOV manufacturers that produce "approved" MOV's, but I
don't know if they can be used to bridge basic insulation.

Dear All,
In Europe MOVs located between line or neutral to earth are not accepted.
Does anyone know the rationale behind this? I believe it has to do with
leakage.
on the other hand, gas discharge tubes are allowed in Euripe between line
and neutral to earth. Does anyone know some reliable manufacturers for such
gas discharge tubes?
Thanks,
Peter Merguerian
