Dave, The last paragraph definitely states that this is acceptable for permanently connected equipment. However, the visual layout is not very user friendly;-- I can see people getting confused. I almost missed this last paragraph because it was visually isolated from the rest of the MOV subject.

I believe the section Rich was referring to is on page 4. I interpret this to mean: Pemanently connected equipment connected to protective earth: MOVS between the mains and protective earth are acceptable in all countries. This is opposite to what Rich's third indented paragraph states. Do others agree with my interpretation?

Varistors between the mains and the protective earth cannot be accepted by the following countries: Pluggable equipment, Type A: Austria, Belgium, Denmark, Finland, Norway, Sweden, United Kingdom. Permanently connected equipment connected to Protective Earth: All countries. There is no specific mention of concern for possible increase in leakage current. I'll send the OSM paper in a separate message. Best regards, Rich
