RE: DEMKO high voltage spacing requirements
There is no such thing as 'DEMKO approval' any more. If you want to export to Denmark, the product must meet the requirements established under the European Low Voltage Directive, just as for any EU country. Hello Paul, If you have a customer that requires you to obtain the D mark, this is a voluntary addition that is available through UL (according to UL's website). You are only required to apply a CE Marking, but can still obtain the DEMKO mark, just be advised that you are not required to do this, unless your customer specifically stipulates it. You could try to convince them otherwise, but as always, the customer usually gets what the customer wants. You need to buy the standard that applies to your product. There are may, many issues apart from the mains circuit clearances. Also, the European mains voltage is 230 V now, not 220 V. Where have you been for the last 10 years?

RE: DEMKO high voltage spacing requirements
Paul - What is the applicable product standard? What type of product is it? What is the application? Is the 220V mains connected? From somewhere else in a primary circuit? Is the 220V in a secondary circuit? What levels of insulation are there between this circuit and other types of circuits elsewhere in the product? If in a secondary circuit, is it earthed? Is it a Limited Current Circuit? What other types of circuits are near it that require isolation/insulation on the board? Limited Current Circuits? TNV? SELV? ELV? Other hazardous voltage circuits?

Re: DEMKO high voltage spacing requirements
Paul, the minimum creepage distance and clearance requirements will be shown in the EN or IEC standard applicable to the product for which the board will be used. These requirements will not be unique to Denmark or to DEMKO. There will be references to other EN or IEC standards that allow reduced spacing, or require additional spacing bases upon the installation overvoltage category, the materials being used, what pollution may occur, and other characteristics of your application. You should research and understand all of this thoroughly beforehand. The best way to avoid an issue with the connector is to specify a connector that meets the applicable standard and has an approval from a CEE member lab.
