A 1.5 HP motor at full load will produce 1.5 HP, which is just over 1100 watts. if we assume 90% efficiency, it will consume just over 1200 watts. On a 110 volt supply this equates to about 11 amps. On a 230 volt supply this is a little over 5 amps.
How many amps does a 1 1 2 HP well pump draw?
When delivering 1/2hp to the pump, it draws 5.0 Amps. If that motor operates at its service factor of 0.8, it will draw 6.0 Amps. Most installations have motors near the maximum load.
How many amps does a 1.5 hp motor?
Common Horsepower to Amps Conversions Horsepower Amps Voltage 1.5 HP 10.4 A 120 V 1.75 HP 12.1 A 120 V 2 HP 13.8 A 120 V 2.5 HP 17.3 A 120 V.
How many amps does a typical well pump draw?
A 240 volt, 1 horsepower well pump draws 10 amps of current. When the pump starts, it can draw up to 35 amps, but only for 5–10 seconds.
What size of generator is needed for 1.5 HP well pump?
Convert horsepower to watts by multiplying the constant value 746 with the horsepower. If you have a 1.5HP pump, the corresponding wattage is 1119 watts. The generator needs to provide twice the power to start and run your well pump. With the example above, you need a generator that has around 2238 watts.
How much electricity does a 1.5 HP water pump use?
1.5 hp = 1 kw =0.3 kwh for 20 minutes per day. Thus the energy required per day is = 1.119/3 = 0.373 kWh.
What size breaker do I need for a well pump?
Pumps Under Maximum Load Well Pump (HP) Volts Req. Circuit Breaker (Amps) 0.5 HP 110V 15A 0.5 HP 230V 15A 0.75 HP 230V 20A 1 HP 230V 25A.
How many amps does a 1.5 hp motor draw at 120 volts?
For example a 1.5 HP Baldor motor turning 3450 rpm draws 13.4 amps on 120 volt service.
How many amps does a 1.5 HP 220v motor draw?
AC Motor Full Load Amperes HP 200 Volts 220-240 Volts 1/2 2.5 2.2 3/4 3.7 3.2 1 4.8 4.2 1.5 6.9 6.
How many HP is 15 amps?
Common Amps to Horsepower Conversions Amps Horsepower Efficiency 10 A 1.45 HP 90% 15 A 2.17 HP 90% 20 A 2.9 HP 90% 25 A 3.62 HP 90%.
How many amps does a 2hp well pump draw?
When delivering 1/2hp to the pump, it draws 5.0 Amps. If that motor operates at its service factor of 0.8, it will draw 6.0 Amps.
How do I know what AMP my well pump is?
Divide the wattage by the voltage to find the current. For example, if the pump wattage is 2,200 watts, and the voltage is 110 volts, the current is 2,200 /110 = 20 Amps. This is the value of the amps drawn by the well pump.
How many amps does a 2 HP pump draw?
AMP DRAW BASED ON HORSEPOWER HP 1 Phase Amps 3 Phase Amps 115 volt 230 volt 2 24 6.8 3 34 9.6 5 56 15.2.
Can you run a well pump on a generator?
Unfortunately no. Unlike many of your appliances that plug into an electrical outlet, your well pump is hard-wired into your home’s electrical circuits. Disconnecting these wires from your electrical panel during an outage and attempting to connect them to a portable generator, is potentially dangerous.
Will well pump work without electricity?
If you experience a power outage, your well pump will not work. You will continue to use water for a short time, as your system draws the remaining water from the well storage tank. However, once that water is used – you will not have access to fresh water until power is restored.
How can I run my well pump without electricity?
#1 Generator While a dual fuel generator may provide the most cost-effective solution, few can produce the voltage needed for a deep well pump to operate. For deep well pumps, a diesel generator will provide a more effective solution as they are both portable and powerful enough to produce the pump’s required 220v.
What is the meaning of 1.5 hp?
The horsepower (hp) is a unit in the foot-pound-second ( fps ) or English system, sometimes used to express the rate at which mechanical energy is expended. It was originally defined as 550 foot-pounds per second (ft-lb/s). A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746 kilowatt s (kW).
How much electricity does a well pump use per month?
At current electrical rate schedules each horsepower costs between $0.10 and $. 20 per hour to run. This means if you have a 5 horsepower pump and it needs to run 5 hours a day to meet your irrigation and household needs you could be spending up to $5 per day or about $150 a month to power your well pump!Apr 14, 2019.
How much power will a 1.5 horsepower 24 volt DC 80% efficient electric motor require?
A 12 volt electric motor has 1,000 watts input and 1 horsepower output. Maintaining the same efficiency, how much input power will a 24 volt, 1 horsepower electric motor require? 1 horsepower, 24 volt DC electric motor that is 80 percent efficient requires 932.5 watts.
How many watts does a well pump draw?
A 1 HP submersible well pump will require a 2.5 KW internally regulated generator to operate the pump. A 30 amp breaker means the pump is smaller than 2 hp will use ~11 amps/2000 watts during operation and will require a 4 KW internally regulated generator to operate the pump.
Does a well pump need to be GFCI protected?
A well pump doesn’t need protection from the ground. The equipment ground is connected to the well pumps. GFCI protection isn’t always superior to proper grounding and bonding. We can’t be sure that users will maintain the grounding connection, so we install the protection most often.
How many watts does a well pump use?
Consumer reports says a well pump runs about 700 watts. Multiply that by 3 to get a rough estimate of the starting wattage for the pump and you run about 2100 which still leaves plenty of wiggle room in terms of wattage.
