I have source 400V 50Hz 3 Phase. Each line is 230VAC and maximum current passing by is 10A. This source is connected two motors and one AC/DC converter (24V out) and it is connected to control circuit. For the power part, I used 2.5 mm^2 cable for connection. Everything worked well and now I would like to make it on PCB. However, I don't know how much trace width should I use?
Furthermore, I have no idea what external, internal layer means (I guess it refers multilayer PCBs out and inner layer), I don't know what exactly means temperature rise.
Low current part (control board) I have already made but power part I don't have much idea. I would be glad if someone can help.
