Hello everyone, I know X (line to neutral) and Y (line/neutral to ground) are required in the line input to the equipment. The question is from which point regular capacitors can be used? (i.e. after an input choke, after a rectifier etc) I guess this the same for IEC 1010 and IEC 950 type standards (I'm currently interested in the 1010).
thanks, moshe valdman PS Are varistors allowed in the mains circuit (line to line and line to ground?) I seem to remember there was a big discussion on this several months ago.
