Hey everybody,
In my PCB there are connected three 220V-250V AC mains wires (L, N, ground), which can conduct up to 16A current.
Could someone refer me pleaes to an article which explains what should be the minimum distance between each pair of wires?
it is hard to find articles on it since it is standards based and they like to charge $100 per spec for the privaledge of digging through obtuse idiocy for the one juicy little tidbit that you actually want.
If board space is not an issue I recommend increasing the distance to 5mm.
An additional safety precaution is a layer of clear laquer sprayed on the solder side (or component side) where ever the traces are located.
Good and longlasting spray laquer is available at Kontakt-Chemie. I received some control devices back from the user when he modernized his control sytem after 18 years.
As I said, they want you to PAY 100USD for the privaledge of digging through 100 pages to find the table or two that tell you that.
Now if you, unlike me, have the 100USD to just throw away (it is much better spent on the food that my wife's insulin and such regularly take off the table), then feel free to contact any of the many standards scumbags and purchase EN60601 or one of it's derivatives.
I am an electronic design engineer who uses it all the time. My company bought the EN60601 spec. It is a bit more stringent than you probably need as it is EU medical.
Occasionally you can find things mentioned in trade show lectures if they happen to be published on the web or in discussions on test lab sites, but they are very hard to find with out author's names and not official.
