Dear all,
In IEC 60601-1:1988/A1, capacitors (X1 and X2) complying with IEC 60384-14, which are connected between Line and Neutral, are exempted from the fault tests (e.g. short circuit).
However, this exemption does not exist in IEC 60601-1:2005 any more. Does this mean that failure of such capacitors can be simulated?
The question proposed since there is a switching power supply that X1 capacitor is before the mains fuse. If short circuit of X1 capacitor is simulated, this design will cause the branch breaker to operate and therefore fail the standard.
Regards,
Roland
