That's very helpful, thanks.
But, one more thing........Who is Chris Robertson?

Subject: [PEDA] Copper Calculations


Does anyone know a simple way of calculating copper track size (in, mm),
when you know the amount of copper (in, ounces), and the current flow
(in, Amps)??
I've never had to do any high current circuits before, so any help much
appreciated.
