The one and only choice for a wire material for a pool pump is copper. Copper has a lower resistance than aluminum which is the other common wire choice. Copper's low resistance lessens voltage drop. The higher the motor horsepower, the more electricity it requires.
Connect an 8-gauge wire to the metal posts of the pool, the pump, and the metal plate on the skimmer and then wire that to the pump to bond the entire pool.
Nonconductive pool shells must have a #8 (or larger) solid, bare copper wire 18”-24” from the inside pool wall under the perimeter surface 4”-6” below the final grade.
Connecting the wrong power supply to your pool pump can result in serious damage. Using an 110v connection on a pump that requires a 220v supply can result in your pump running slowly or not working at all. Applying a 220v supply to a pump that needs an 110v input could damage your unit beyond repair.
Speaking from experience (both professionally and having a pool at home), you need a minimum of 12 ga wire for a dedicated circut and thats pushing it being 80' away. 10 ga would be better especially if you plan to add anything else (lighting, cl2 generator, etc).
1 HP is 746 watts x 1.5 HP = 1,119 watts. 1,119watts ÷ 120volts= 9.325 amps.
If you turn it on and the display lights it is probably working. In any event, if you turn on the meter, turn the knob to the 750 ACV position, put the leads on the wires in the pump (white and black or black and black) you would be able to see if you have 115 volts or 230 volts.
Consequently, in-ground pool pumps require 240 volts. You won't be able to plug them into any old outlet on the inside or outside of your house. Above ground pool pumps, on the other hand, run on 120 volts. This means they could be plugged into a regular electrical outlet.
So, if the wire in the extension cord is too thin then the cord can eventually burn up or overheat causing the pump not to run. Also, because the pump uses a lot of power, the outlet that you plug the extension cord into should be on what is called a “dedicated circuit”.
GFCI Breakers And Swimming Pool Equipment – What We Know And Our Recommendations. The National Electric Code requires that all swimming pool pumps be connected to a GFCI breaker.
Running your pump with an extension cord voids the warranty in most cases. Running the pool pump motor with an extension cord that is not adequately paired for the filter's power will damage the motor. At times, pool owners, however, use extension cords in lieu of a costly job to bury a power line beneath the ground.
Booster pumps for pool cleaners or solar systems can be operated with 110V or 220V, and are usually connected to a separate timeclock, powered with a dedicated 15 or 20 amp breaker. The wiring of the motor is identical to the wiring for the main pool pump.
Most well pumps both 120 volt and 240 volt can be wired with standard romex inside the home or property. The wire size is 14 gauge awg or larger and is usually protected by a 15 or 20 amp circuit.
The control box has the power cables that go to the submersible well pump. Above ground pumps will have a label on the motor that has a label. The label should indicate the voltage, most likely 220 or 230 volts and the horsepower or current draw (in amps) of the pumping equipment.
If it is a 3 phase motor then it can be wired incorrectly and then it will run backwards or If there is trapped air in the system it can reverse when the pump turns off. This however will break the impeller if you turn the pump while it is spinning backwards.
(1) Install a 20 amp GFCI at the main breaker panel for the dedicated 240 line for the pool pump. Neutral wire from GFCI attaches to ground/neutral bus which is the same at the main. (2) Add 240 Disconnect by pool pump. (3) Add Intermatic PS3000 surge protector by connecting it to disconnect.
Most Energy Efficient Pool Pumps
Calculating Pool Pump Energy Use: Each horsepower uses 746 watts. For a 1.5 hp pool pump, multiply 746 watts by 1.5 hp, for a total of 1,119 watts. Most utilities charge from 10¢ to 15¢ per kilowatt-hour, and to know kilowatt-hours, multiply watts X hours and divide by 1,000.
If you are wiring for 115V, the three wires to the pool pump will be black, white and green. Attach the black (115 V) wire to terminal 1 of Line 1 (L1). Attach the white wire (0 V) to terminal 3 of Line 2 (L2). Attach the green wire under the Ground screw (GND).
Since it's an aboveground pool pump it's an uprated model and probably draws in the neighborhood of 10 to 12 amps at 120 volts.
Cable size calculation formula:
The cable size is equal to the 1.5 times of the full load current of the motor/load. Hence the cable rating formula can be written as, Cable size = 1.5 x Full Load Current.
Check wire size. Motors are hot to touch. Provide ample circulation around motor. For example: 1-1⁄2 Hp motor at 115 volts over a distance of 150 feet, use #8 wire.
