Table Saw tripping circuit breaker

[craigjc]

Hi
Im a electrician, if the RCD is not breaking (the two wide ones to the left) and it does 8amps under normal load (will do like 2amps under no load) and the C/B is 16amp, then there is ether something else pulling amps on that C/B (you only have two power point C/B's so the whole house plugs are split onto two breakers) the other is the saw; theres a short some where or theres to much friction from the gears, bearings even in the motor its self.

Take the chain off the motor and see if you can hand wheel it with ease (the motor and the saw) to see if there is any friction in any, if there are then thats the problem. If its the motor you need to get a new one. If its the saw then you will have to pull it apart to find the problem (most likely a bearing).

I'm no sparky, but it sounds to me that a dedicated circuit is required. And how about the sellers form? Offered the buyer a refund. Clearly a forum member and deserves a greenie I reckon.

I'm sure it will all work out for you.

The prime issue that Craigjc ( electrician) identified is that the saw is only supposed to draw 8 amps. Therefore, if you put a heavier circuit in place, the saw may not trip the breaker but it would still be drawing a current higher than 8 amps and the cause of this would not be addressed. I think it makes a lot of sense to analyse the current draw in the first instance, which an electrician can easily do.

Yes and it will make it dangerous, if left to pull that many amps (over 16amps more than double the rating) the motor will over heat and catch on fire!

The other thing that could be wrong is the motor's coil winding's, if they are damage in anyway, most likely over heating (too many pieces of wood getting jamed) if thats the case NEW motor.

The electrician will most likley say your C/B is fine, your saw is stuffed, get a motor electrician out here, that will be $120 thank you, bye bye!!
