How do I change the electric wire in a franklin ground water pump from 230v to 115v? I purchased a Red Lion 3/4 hp convertible ground water pump but must change the power and wiring from the pumps default 230v to 115v. I believe I changed the black plug properly but have no idea about the white & black wires in the wire to the electric outlet. Where do I connect those ends to the pump?

You have 4 wires coming out of the fuse box , one white , one bare, one black, one red, right? The fuse is a double pole, 220 volt, ?30?amp, guessing, and you are now wiring up to a 110 volt, motor which needs 20 amps, so, remove one wire from the breaker, red or black, shut it off first, pull the wire off, tape it and mark it what it was. leave the red wire on there, or the black, it doesn't matter, Now you have one hot, one ground, one neutral, hook them up to the pump, the box on the pump has screws, one silver, one brass, the brass is always hot, the colored wires are always hot, The silver screw is neutral, the white is neutral, always, and the ground wire goes to the ground screw, maybe outside of the box. You should be all set, tape off the old colored wire you didn't use and mark it . You might need it someday. Hope this helps.

I have a AO smith ST1152 and red black and green wires. How do I wire it


Verify the voltage to the pump. These days motors and pumps largely are set to run on 230v out of the box (for in ground pools). If your supply voltage is 115v, the motor will run at half speed. This would cause poor suction. If this is the case, do this:

On the side of the motor there is a diagram on how to convert the wiring from 230v to 115v so it will run on the correct voltage. Most of the time, that's the issue. Flip the breaker off before working on it.

Changeing 115volt to 230 volt


Most power Flo pumps run above ground pools and run on 115v only.You can look at the wiring diagram on the motor label to see if it is convertible, it will show wiring configurations and amps for both 115v and 230v. If not, it is a 115v motor only.

Hi Eglenni,

Here are the specs for your pump:

Thermoplastic Shallow Well Jet Pump 3/4 HP. This new revision of an "old hand" provides good pressure pumping from wells where the depth-to-water is 25' or less.

BODY CONSTRUCTION: Thermoplastic
HORSEPOWER: 3/4
MAXIMUM CAPACITY: 12 GPM
FLOW at 10' LIFT and 40 PSI: 9.7 GPM
MAX LIFT: 25'
MAXIMUM PRESSURE: 78 psi
PRESSURE SWITCH SETTING: 30/50
SUCTION PIPE SIZE: 1-1/4" NPT
DISCHARGE PIPE SIZE: 1" NPT
AMP DRAW (full load): 6.1 amps on 230v / 12.2 amps on 115v
VOLTAGE: 230v / 115v, 60 Hz
RECOMMENDED BREAKER: 15 amp on 230v / 20 amp on 115v
MAXIMUM WATER TEMPERATURE: 140 °F (60 °C)
=========================================
Note that this pump can be operated at 115 volts or 230 volts (A/C) It may have come wired for 230 volt use from the vendor.

Make sure the pump is piped correctly.


There should be a wiring diagram either on the pump or in the literature so you can check to see how the pump is wired.

MAKE SURE
you have the pump wired for 115 volt use in your case. Also make sure the wire size is #12 awg for the power wiring.
Make sure all connections are tight. If you have an amprobe (an instrument that measures electric current) you can check to see how many amps the pump is pulling when it runs.

You said your old pump was 1 HP. This Flotec pump is 3/4 horse so there could be some pump performance loss depending on the well depth and length of the piping runs.

Here's the link to the website for the pump. There are additional resources available on the website:

Your black and white wires go on L1 and L2. It will not matter which wire goes on with line terminal as long as you just put one cord wire on L1 and one on L2. Be sure you properly switch the motor to run on 115V since it will facotry prepped for 230.<br /> <br /> John

A o smith b854 motor schematic diagram 115v . How do I hook up 115v to the factory set 230v?


Remove the back of the pump housing ... inside you will find the 110 volt connection place.

If your pump is on a dedicated line (as it should be) run it on 220 VAC ... To convert your line from 110 to 220 all you need is a double pole breaker of the proper amperage ... take the white wire presently on the ground bus bar and put it on the other side of the new double pole breaker. Then you will have 220 ... and you will save a few bucks on electricity.

John what you have is a 240 volt motor on that pump. It will not connect to a 120 volt cord. You'll have to get a different pump.

However, I believe that this motor will be more efficient at 230v depending on load conditions. At 115v this motor will draw more amps and tend to run hot, but situation rules. Enjoy
