Hi Wouter,

I use the PCB track width calculator at this website to set my lower limits
when designing my PCBs for high(er) power and voltages:

It's always good to make your traces wider and clearances larger, if
possible, to give yourself a bit more headroom.

You can get either PCB spade or screw type terminals from manufacturers
such as Keystone or Zierick. I've used both methods before for up to 480
VAC. You can also use some of the larger Molex or AMP connectors although
you may have to "skip pins" to keep adequate conductor spacing.
