Hello All I'm still groping my way around the 7th edition of IEC65 (EN60065:2002) and would appreciate a little help with creepage and clearances.
A designer wants to place a ground plane above a mains track on a pcb, contained within a 230V rated domestic type product. As far as I can tell, 1) The minimum thickness of the pcb material between the ground plane and track should be 0.4mm, the insulation resistance between the two be 4Mohm and the dielectric strength test be 3kV(rms). (Clause 8.8) 2) Using tables 8 & 9, the minimum clearance between the ground and mains track should be a minimum of 4.0mm (if no quality control program is utilised). (Clause 13.2.2) 3) The minimum creepage is the same as the clearance value (Clause 13.4) Any comments would be much appreciated.
