I think fuigb is on the right track. The starting current for a motor can be 3 to 5 times full load current. I don’t know what size motor your saw has but say it’s 2 hp. You could be pulling 50+ amps on start. Probably right on the edge for instantaneous tripping that 20 amp breaker. If it was me, I’d go with #10 wire and a 30 amp breaker.
