Submersible Pump Cable Sizing

Your pump needs electricity to work.

Submersible pump cable sizing.

The pump size tank size and other controls should be selected to keep the starts per day as low as practical for longest life. How are voltage drop calculations used in sizing submersible pump power cables what happens when the power source for a submersible pump is not located near the pump s control box. A jacket covers the insulated conductors which provides more protection than twisted pump wire in places where abrasion is likely to occur. Submersible pump cable is used between the wellhead and the pump in submersible applications and is approved by underwriters laboratories ul for underwater duty.

It is designed to safely carry electrical loads inside water wells so long as it is sized properly.

Home pumps wells well pumps franklin electric single phase submersible motor wire sizing franklin electric submersible motors wire size single phase 2 or 3 wire cable 60 hz service entrance to motor maximum length in feet. Hp 5 hp 75 hp 1 hp 1 5 hp 2 hp 3 hp 5 hp pump wire configuration 2 wire 3 wire phase 1 3 site voltage 115v 230v clear filter cross reference the distance from your pump to the electrical service entrance to determine the correct gauge.

Most submersible pumps with 5hp or less are 230v single phase. We stock lengths of wire from 50 feet to 1000 feet in 8 10 and 12 gauge. If there s no power on site you need to spec a generator. The key to sizing a submersible well pump is to calculate the gallons per minute of water required during peak periods.

You ll need 1 5kw per motor hp so a 5hp pump needs a minimum of 7 5kw you also need to spec the right power cable pvc flat jacketed wire is the most common. Aqua science offers pvc submersible solid core twisted 2 and 3 wire with green ground wire for deep submersible pumps and double jacketed direct burial type uf b feeder wire. For one thing the pump s power cable must be sized to limit the resultant voltage drop to less than 5. The number of fixtures gives you the gallons per minute gpm required by the pump.
