What is the current of CAN protocol in frc?
It’s measured in mA, so almost any common gauge of wire should be good.
And for PCB trace width?
The easy answer is 10 mils, but you haven’t told us the copper weight you’re using.
Here is a relevant bit from the data sheet of a CAN transceiver I’ve used many times, the TI SN65HVD251:
