I have one 15-amp circuit serving my basement shop. Can I switch the breaker to 20 amps? TS is tripping when ripping 6/4 maple.

You haven't provided enough information. The breaker
protects the wiring and any attached devices (e.g. receptacles).

What AWG is the wire from the breaker to the receptacle for
the table saw? Is the receptacle rated for 20A?
