I am building a dual Torque Board 6355 with a 12s2p A123 battery that can handle 140a. My intention, though, is to max 50a per VESC = 100a total continuous capable. (maybe 45a x 2 to not stress the VESC’s out too much).
If you search online for copper wire ampacity (given, all of the sources I find are for electrical wiring which are longer runs) suggest 12 awg ampacity is only 20a. I think the gauge wire on the anti-spark switch I have from DIY is 12awg (maybe 10awg, but even then I read that 10 awg is only rated to 30a).
I also have Flipsky’s anti-spark boards and can build my own switch with 8awg wire, but again, I read 8awg is limited to 40-50a. I need double that.
Do I need to run 2 anti-spark switches? 10/12awg doesn’t seem like enough for 100A load.
