Long story short. After a tune up, I did a 45* bevel cut and the blade hit the insert (some tune up). I hit the off button and it was a few minutes before I realized the circuit breaker had blown. I reset it and have power at the receptacle but the motor is stone dead.
It’s a Delta contractor saw with dual capacitors. It has a red button on the end of it like a reset button on power cords. Tried that to no avail. Seems like I burned up the motor but it’s hard to believe (maybe I just don’t want to).
Any suggestions as to what got damaged and how to fix?
Any feedback greatly appreciated

Dear friend,
If it smelled as burning there is little chance. But if there was no smell of burning, there is hope.
Try pushing the reset button harder. You might also have a starter which has overloads on the contactor, that would have to be reset, too.
You can also bypass everything, remove the blade, disconnect the motor and energize it directly. Check the magnitude and presence of the voltage.
If it is a capacitor, you can still hear a hum. If a hum, then a slight rotation at the shaft could initiate rotation.
Good luck.

No burning, smoke or anything else.
Will try your suggestions. Really appreciate the feedback
Contact Delta service. They are very responsive.
If motor won't go at all,
do follow the good advice of contacting your supplier, or Delta.
It would be correct to claim that the motor's overload protection did not protect the motor, even in the situation you describe.
The overload protection is independent of what causes the overload and it should have worked. That's what it's for.
The situation you describe of tuning your table is not an improper use, even if you were a little off, it was not intended. It could have stalled on a knot of wood, no difference.
Can you turn the motor by hand? Get a voltage tester (the type that ticks) and follow the wires with it till you get to the motor. you might have blown a connection and not the motor. Check before and after the switch for power.
To All
Thanks for all the responses. Will follow up on Monday and post the results.
Monday night:
the problem turned out to be the power line which connects under table to a short extension running from the motor. It got clipped when I did the 45* cut (not sure why). I have spliced it back and re-connected it outside the base frame.
The saw runs fine now but I think I'll order a replacement part from Delta to be on the safe side especially as I plan to upgrade the motor to 220v soon.
Thanks again for your responses. This is one fine Forum.
