Unisaw motor tripping breaker.
rlpeterson posted a topic in Machinery, Tools, Research, Reviews and Safety
Hi, I have an Unisaw and I bought it second hand about 10 years ago. Up until a few days ago it was opperation fine. But after ripping a few boards, when turing the saw on, the blade rotated slowly and then the 20 Amp breaker tripped. I attempted this a few more times and the same thing happened. I have a planer on the same circut and it worked fine. I took out the capacitor and the other fuse and had them tested at a motor shop and they told me that they were fine. I will attempt to switch the breaker on that line with another, but with this information, what else should I look a that would cause it to draw more amps than normaol on start up? The brushes? Also when I took the capacitor out, it was chuck full of saw dust and I had to take a tool to get the sawdust cleard out to see the connectors on the capacitor. Do you think this may have been an issue, sawdust on the points? Best regards, Ron
