Hi Peter, thanks for the reply.
The trace will be about 1 ozCU, so at 3 amps and less than 50mm long I should need about 50mil traces. I have used two 48mil (one top and one bottom) traces per 230V connection so it "should" be enough. However, I would rather have a wider trace on one side of the board and have it surrounded by some Copper Fill which I want to connect to a ground point.
I have seen some talk about increasing the max trace width (currently 48mil) but I can’t find a way to do this. Also, as far as I can find out it is a good idea to have a minimum of 3mm clearance between a Copper Fill and high current traces. I have seen some discussion about changing the Copper Fill clearances in Fritzing but unfortunately nothing definitive.
Does anyone know of a way to increase the trace width and/or increase the Copper Fill to trace separation?
Thanks.
