Topic tags/keywords: question

I have had no problem at all with my table saw for at least 5 years, but turned it on this morning and the fuse box in the workshop tripped out.
Checked wiring in stop/start switch and all seems ok. Tried again and fuse tripped again.
Any ideas what it could be or what I should check for?
Pete.

Check the outlet. I know that my 240v plug end shows arc spots over time. A loose connection could be the culprit and finally opened up. Just an idea.

Does the motor hum? It the breaker trips as soon as you turn it on check for a pinched or cut wire going to the motor. Unplug the saw and start checking the wiring as soon as it leaves the switch all the way to the motor. If the wiring is good it may be a starting capacitor or starting winding depending on the type of motor in your saw.
If the motor hums for a few seconds try to turn the blade by hand to make sure there is no binding.
Lastly you can unwire the motor and tape the ends. Turn on the switch. If the breaker trips it’s a wiring / switch issue. It not it’s probably the motor.

Posisible the breaker has become weak. That happens.
Is the saw 120volt.
If it is you could plug another high wattage load into the same outlet and see what the breaker does.

Echo knottscott….. What saw do you have? is a really important question.. magnetic on off.. could mean a fried capacitor in the low voltage system. other motors and systems could still be dangerous after they are unplugged, and would need the hot grounded to discharge the starting capacitor…. what saw is really important to help trouble shoot this problem. Echo horizontalmike… pics of the plug and the electrical service would help as well as model and serial numbers…they would let us know amp and other ratings etc…
shop situations… this is the time of year rodents bed down for the winter… and tend to chewww..

Wow, unbelievable the knowledge that the members on here have to offer.
I am going to check the simpler suggestions this morning ie wiring breaks etc.
Also going to plug in another machine int the socket and check that it works ok.
The blade turns freely (With motor switched off lol)
It’s a Rexon 240volt.
Thank you all for your suggestions, very much appreciated.

Do you recall EVER dropping any piece remotely near the power cord? (think pinched cord)

Worst spammer ever. At least get your HTML code right if you are going to embed links to increase page views.

Are you using an extension cord?

No Lumberjoe, just plugged into wall socket. Have tried plugging into a different socket, but same result.
Checked all wires for kinks, all ok.
I did take cover off the start switch box, but quickly put that back when I saw what looked like a coil and other connections, that’s not for me I think that it would be safer for me to get someone in who know’s what they are doing!! lol
