To answer this question the voltage of the motor must be stated. I = W/E. 1 HP equals 746 watts.
That depends on the power requirement of the sump pump. A 1000 watt generator (if this is running watts) will produce 1000 watts continuous. Through some simple math, this is equivalent to 8.33 amps at 120 volts. Current (in Amps)=Power (in Watts)divided by Voltage (in Volts). On your sump pump, there is something called a nameplate which lists model number, serial number, manufacturer, and power requirements. The power can either be listed in watts directly, or in amps (at 120v). If it lists watts directly, this number is either higher or lower than your 1000w generator. If it lists amps, your generator will supply 8.33 amps continuous, as figured above. Likewise, you can find out if your generator can power any given load by using this method. Just divide the listed wattage by 120 to get amps. Also, motors do pull higher current when they start, so it is usually recommended to size the generator larger than you would otherwise when you are running a motor, such as your pump. If the sump pump is right up there at 8 amps, it would be pushing the limit to expect it to run the pump. Some smaller generators too are so-called "inverter" units, and many of these are not recommended for motor starting duty. Check the generator's manual to be sure.
Sump pump motors come in various sizes. To give an answer, the HP or voltage and amperage of the motor must be given. You may find the following formula useful. Watts = Amps x Volts.
This can not be answered with the information you have given. 60Hz does not relate the the current draw so wire size can not be calculated.
Using the formula: Amps = Watts/Volts look up the wire size needed in the national electric code book for the amperage of the device. This formula only works for single phase current. If you are using 3 phase, look in the book. In general, 15 Amps or less: 14 Ga Copper wire. 20 Amps or less 12 Ga. 30 Amps or less 10 Ga. Anything more than 30 amps, look it up in the book.
A #6 copper conductor with an insulation factor of 75 and 90 degrees C is rated at 65 and 75 amps respectively.
To answer this question the pump's voltage is needed.
A water pump has a "weep" hole. When the seals start to wear out the water pump will still start to leak from this hole. When this happens it is time to change the water pump.
Voltage of the pump (12) multiplied by the current draw = the watts used. This would be 12 watts if the current was 1 amp, 24 watts if the current is 2 amps, and 36 watts if the current is 3 amps, and so on...
Not necessarily it all depends on how many amps it draws.
It would depend on how deep your well is, and how efficient the pump.
By filling the sump with clean water until the float kicks in and then the pump will start when the correct water level is reached
A blockage in the downstream side of the pump could make this pump work harder raising the amps as the pump now has to do more work to get through the line. An upstream blockage would make the pump spin more freely lowering the amps on the pump as it will not be doing any work.
In most cases the water pump will start to leak coolant when it is going bad.
The factory pump uses 6 to 9 amps depending on the condition of the pump. A worn pump uses more power of course. I don't know what problems if any you are having but if you blow a 10amp fuse then change the fuel filter, a pluged filter will make your pump work much harder. Still blows? Then time for a new pump. Aftermarket pumps such as a Walbro pulls almost 15 amps.
A fuse blows if if an item is drawing too many amps or if there is a short in the circuit. DO NOT USE A HIGHER RATED FUSE - YOU CAN START A FIRE !
The horsepower of the motor is needed to complete this answer.
A pool pump motor which is drawing half the amps listed on its nameplate can indicate a problem with the windings or a lack of incoming current. Pumps will only draw as many amps as are required to operate under the current load.
