Generator size question.

[Huntindad]

yep, another generator question... I am not knowing about water well pump wattages...so,

My old Powermate(coleman) generator is not putting out enough volts. I've swapped out the voltage regulator and fixing to change the brushes. If that don't work, gonna buy another one.

I need one to push a well motor. It is a 2 HP(or 1.5) not sure. about 220' down to motor.

Been looking at the Westinghouse 5300/6600 watt model.

would a 5K generator be enough so as to not harm the motor. It would be used once or twice a month to fill a water tote I have at my retirement property.

thanx,

You really need to know the amperage your well pump pulls. Look on the nameplate of the pump panel. It will usually tell you what HP it’s rated for and the amperage. You can use that info to size your generator.

You are looking at +/- 18amp continuous at 230VAC if standard 2HP.

Let me look to see if I have a picture of the motor info on my phone. If not guess it will be the weekend before I can check.

I found the picture on my phone.

it says 1.5 hp and S.F. MAX AMP 8.0/11.5

Anything you mentioned will work more than enough. You could honestly run it off of one of those 2000w small generators if it were 120v.

Your service factor of 8.0 is probably for 230 volts and the 11.5 is for 115 volts. Either way you are good with a 5k generator. You shouldn’t use anything less than 12 gauge wire though.

Maybe 10 gauge by the time you factor in voltage drop.

thanx guys,

I will make a connection with some 12 ga. wire with the 240 outlet to the pressure switch.

[Huntindad]

Maybe 10 gauge by the time you factor in voltage drop.

the generator will be 10' from the pressure switch.

[Arrow-Tek]

the generator will be 10' from the pressure switch.

You should be good to go then.

[Huntindad]

appreciate it folks.

Handy link here that I use for generator sizing.
