[QUOTE="NascentOxygen, post: 5847758, member: 336970"] If the load doesn't have a return wire then it draws no current so is not a load. The "earth" wire you want to not have is just a convenient way to represent the essential second wire for current that powers the load. I think it should be termed the "neutral". The purpose of the filter is to provide a path that bypasses the harmonic current around the load, so the passive filter needs to correctly connect in shunt with the load. The connections need to be low resistance, so will be copper wires (even if one is named "earth"). [/QUOTE]
