Fusible link or not?

Some off the cuff real world info on circuit breakers. Certain models of our power chairs use 2 - 70A breakers in different main circuits. That is, 140A total. The motors are only fed with no10 wire, but in a dead stall with the joystick firewalled, they can pull OVER 200 (100+A per motor) that is right TWO HUNDRED amps for maybe 15 seconds AND NOT BLOW THE BREAKER

To put that in perspective, that's about 110A per no10 wire. Your typical home electric water heater is often fed off a 30A breaker with no10 wire

Everytime I build a drive module, I test it on a "test chair." I've stalled those hundreds of times and never popped a breaker or burned up wiring or a motor. I am amazed every time I do this!!!! Typical stall for me is about 215-220A forward and maybe 205 in reverse.

The point is a breaker may not be quick enough to prevent "burn down" especially if it's oversize
