Thank you for posting your question here on Fixya.com.


Is it the breaker or the thermal overload that trips? Something is causing the pump motor to overheat and shut off to avoid permanent failure.


The motor is likely failing. It may be a small part such as the capacitor or the starting switch, but could also be more severe such as the winding itself. You will also want to examine the shaft to see if it is damaged, bent, or the bearings failing or seized.

If you are not familiar with testing these parts your best bet would be a local electric motor repair shop to see if the motor can be repaired or if it would need to be replaced.

My hot tub has an issue. Only half the display is working, there's no heat and the jets wont turn on. If I trip the curcit, I can get the hot tub jets for 10-30 seconds and that's it. HELp


Almost all hot tubs use 230 volt AC power which comes from the power company in two power wires plus one common common wire. You get common 115 volts between a common and either other wire. "Half way" working could well be an attempt to run on only one of the wires. There is also likely to be a ground fault circuit breaker in the wiring which makes sure current going out to the tub is all returned via the wires and not through someone's legs to ground. If you're comfortable with an AC voltmeter check some voltages but understand that 230 volts is way into the killing range. Two people present and well insulated probes are important.

New leeson 3 hp motor for my tablesaw has very little torque, and is less powerful than my old 1hp craftsman motor. What could the problem be?


If the motor is a 115/230 volt motor and is running on 115 volts but the wiring is configured for 230 volt operation, the motor will be weak.

Does not get hot


Many 230 volt electric Dryers will run and time out fine with only 110 volts at the receptacle. Many people will call a service man just to find out that they had a tripped breaker in their electrical box. If you know you have proper voltage at the receptacle chances are that your heating element is bad.

20 amp Circuit breaker trips everytime I flip the motor switch on. Its a craftsman table saw motor 1HP Model 113-12070., 14/7 amps


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!

I want to re wire an electric motor for low volt


Look on the name plate. If it says under 'volts' 120/240 that means it's dual voltage and you can use either voltage to run.

Pump runs 3 mins turns off


Sounds like the pump is overheating and tripping the high limit. If it reaches a certain temperature, the motor will shut down to save itself. This is usually from inadequate line voltage or possibly a bad run capacitor or a problem with the windings. This can also be caused by running the wrong size impeller. If you have a one horsepower motor, you can only run a 1hp impeller or smaller, never bigger. So if you've had work done on this pump recently, make sure the impeller is not rated for more than the motor can handle. So, first check for good voltage, then check the capacitors for "bloating" or leakage, and check that the impeller is properly sized. I may have missed something, I write again if I think of any other reasons...

I wired a new dura-glas pump as a 115, and it popped the breaker. I put the black wire on 1 and the white on 2. Should I have wired it as 230? Should I switch the black and white wires, even though the...


The wire placement does not matter assuming you have a 115 volt supply with a three wire cord/cable and they are comming in as blk=hot, white=neutral and copper=ground.

Tripping a breaker would be from a shorted hot wire so look for a place where it touches the white or ground wires or the metal of the motor. Another cause would be if you really have 230V across the black and white and you connect it to a motor set for 115V. Is the breaker that turns off the circuit in question a signle wide or a double wide breaker. A double wide would be 230V.

Electrical installation


From the specs that you are showing 800 watts @ 230 volts will pull under 3.5 amps. I would install a 20 amp 220 volt circuit with #12 wire. Just double check if the tub requires a 3 wire ckt (2 hots & ground) or a 4 wire ckt. ( 2 hots, neutral & ground) Make sure the ckt. is GFCI protected!

Generator electrical


On a 230 volt std hook up here's the way it is supposed to work. From black to white you should get 115 volts. From Red to white you shoudl get 115 volts. From red to black you should get 230 volts.

Concentrate on getting the correct output from the generator with the load to the house disconnected

This should be 115v (black to white, 115 volts red to white and 230 volts red to black.

On the load side (ie, the house connected) what are you using? 115 volt lights, etc on one side of the
230 volts, and some other 115 volt loads on the other side.. Are there any 230 volt loads. It could be
that one side of the 230 volts (ie, a 115 volt side is drawing a lot more current than the 2nd 115 volt leg.

Get back with me on just what the loads are botth 115 volt and 230 volt . also what are the rating on the circuit breakers.
