Question about Saws
Trips circuit breaker
It is against code to simply put a 30 amp circuit breaker into a line that is rated for something lower like 15 A or 20 A. If the saw draws a current higher than what the lines can handle you can have a fire. The circuit breaker may be able to handle it but the lines in the wall won't be able to.

Sounds like you may have overheated the motor. I'm surprised the overload on the motor didn't trip first. With this overheating, the windings in the motor have basically shorted out to ground. This is why your breaker is tripping. Rewinding the motor is no longer the option these days. You can try going online to www.searspartsdirect.com

I assume that you are using the motor on 115 volt service. Remove the drive belt and check for excess friction in either the saw arbor bearings or the motor bearings. If both seem free to turn, then suspect that the start capacitor on the motor has failed. They usually become open circuited which prevents the start rotation. It will just sit there and hum loudly until the breaker pops. You may also have a defective 20 amp breaker--you will need a clamp-on AC ammeter to verify. Suggest that you run the saw on 230 volt service when you get it running. You will be amazed at the acceleration and apparent power available. My table and radial arm saws are both set for 230 volt operation and love it. Go to: Searspartsdirect.com and enter the complete model number minus the decimal point. This will take you to a series of drawings that list all replaceable parts. Hope this helps!
