After searching around the net I find there is SO MUCH controversy about this, I’m uncertain what to believe. I’ve learned the difference between clearance and creepage. Here’s a snapshot of my pcbs layout. I have 6.6mm clearance between the 120VAC pin on a relay and the closest 5 volt trace. From what I’m reading that should be plenty, but a confirmation of this from someone who’s more familiar with it would be nice. Does someone have a recommendation on a reliable chart/source for this information?
