creepage pcb distance with "different voltage level" on board



  • Re: [Clearance](creepage and other safety aspects in "MySensors" PCBs.)

    Hi,

    We use off line application. I have a doubt about creepage distance. We powered hte circuit (pollution degree 2) with 230Vac+20%=276Vac after the rectifier diode we have 390Vdc. For a double insulation, where I have 276Vac creepage distance is 6.4mm, after the diode (390Vdc) 8mm. that's right or I have to use 8mm everywhere. Thanks.
