   The high-voltage tracks are MUCH fatter than the low voltage tracks on   
   the PCB, as you can clearly see in the photo of the underside of the   
   board, and high and low voltage sections of the board are well separated.   
   My main concern would be the high voltage tracks heating up and   
   deliminating when the current gets really high, but I think they are OK   
   for 10A.  Looks pretty good to me.
