As I said, the breaker is probably rated to high. It wasn't meant to protect against drawing too much power, it was meant to protect against a short.

The attempt was to start an Acura on 10 gauge, which would draw close to that amount if it could.

if it's for a second or two a peak power it might be fine 300amp breaker is incorrect for a normal load on #10 it offers no protection

a starter is connected via relay directly to the battery for 300 amps or so they most likely use #4 wire

most car MEGA fuses are 100 to 200amps rated short to ground
