I'm not an expert either, but plugging in 15A produces a trace width of 274 
mils (for 2 oz copper).

However, this is assuming long traces, so if you keep the traces short and 
connect them to large heat sinks, you won't have to make them as wide. One 
trick is to use large pads, and connect the pads with wire jumpers.
