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.
