VFD (?) tripping RCD

[russell]

Russell, are the Chinese spindle / VFD combinations likely to do this too?? I suppose I'm asking if this filter is an "EU" thing or world wide??

For anything to be "placed on the market" i.e., sold anywhere in the EU it must comply with all relevant EU directives. It is not a worldwide thing. However for such things to be sold in the USA it must comply with FCC regulations which are basically the same. As that is the largest market for Chinese goods they are likely to comply.
