Hello Jim You can find CTL and OSM decisions which will have information about the use of MOV's at the following link
http://www.iecee.org/ctl/OSM_decisions.htm The OSM decisions are the result of meetings held by participating European Agencies where clarification is offered for standards interpretations. These are not legally binding but I have found them a big help in understanding how the Agencies interpret the standards....You can also find CTL decisions which are very helpful. I did not see 50178 listed but I know EN60950 and EN60065 have concerns with MOV's line to earth so you may want to use this as guidance......... Hope everyone finds this useful.........

Attached is a WORD file that has a section of an older CCA document that addresses this issue. I got it from a TUV office.

Or has that gone away? Any other countries with the same or similar rules? We are not in EN60950 - this is an EN50178 question, but really it's a general question. Thanks, Jim Eichner, P.Eng.
