The power wires between the saw and the socket might be to light.
Simple as that. Or - the power wires to the socket from the breaker is
to small in diameter and out of spec. Might be a spliced one with
other service tied on to it.

What is the HP of the saw ?

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.

I would like to know what is going on with the voltage. If you have 120 volts and it drops to say 90 volts when you cut the maple you have a problem and changing a breaker is not the fix.
