What size breaker does a well pump need?

Reach4 Well-Known Member

The manual for your pump probably recommends a breaker size. For a 1/2 HP submersible pump, a 15 amp 2 pole breaker would be normal. You can run 12 AWG, but unless the run is very long, 14 AWG is sufficient.

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.

Secondly, does a well pump need its own circuit? Check the power to your well pump Water well pumps are powered by electricity. They are usually run on their own circuit, which you can check in your home's breaker box.

Moreover, how many amps does a 1/2 HP well pump use?

Taking the 1/2 hp, 230 V example, when delivering 1/2 hp to the pump it draws 5.0 amps. However, if that same motor operates at its service factor of 0.8 hp (1/2 x 1.6) it draws 6.0 amps. In most installations, motors operate near the Maximum Load.

How many amps is a 3/4 HP well pump?

Re: Amp draw on a 3/4HP pump Running amps will be 6 to 8 amps.

How many amps does a 1 HP well pump use?

1 HP submersible pump motor will draw a current of 3. 2 amperes if it is single phase motor at a voltage of 230 volts, and if it is a 3phase motor at a voltage of 440 volts, it will draw a current of 1.7 amperes, maximum.

How many amps does a 1 HP well pump draw?

A 1HP 240 volt pump pulls 10 amps while running. On start it will pull 35ish amps, but only for . 5-1 second. 240 x 10= 2400 Watts but you will need a surge capacity of around 8000 watts as the start amps are much higher.

Will a 5000 watt generator run a well pump?

Homeowners can often power most household appliances using between 3000 and 6500 watts. If your home has a smaller furnace and city water, you can generally expect that 3000-5000 watts will cover your needs. If you have a larger furnace and/or a well pump, you will likely need a 5000 to 6500 watt generator.

What can a 1000 watt generator run?

Appliances Suited to 1,000-Watt Generators Light bulbs – as indicated on bulb: 12 watt, 60 watt, etc. Laptop computers are 250 to 500 watts, starting and running. Desktop computers are typically 600 to 800 watts, starting and running. 4-cup coffee maker – 600 watts, starting and running.

How many amps does a 1.5 HP well pump draw?

Member. A 230v 1.5 HP submersible pump is metering about 11.4 amps per leg. The motor nameplate states running current to be 10.6A. Metered starting amperage only increases about 1A above running amperage.

What wire do I use for a well pump?

The majority of submersible water well pumps require four wires for installation. There is a red, black, yellow and green ground wire, twisted together to keep the wires compact going into the well. Order your submersible pump electrical wire today.

Can you run a well pump off a generator?

If you have a 1 HP pump (746 watts) a 1000 watt generator is NOT large enough to run your pump. In the case of a 1 HP standard submersible well pump; a 4-5 KW generator is required for the well pump even though 1 KW is the amount of power the pump uses when it is running.

How many amps does a refrigerator draw?

A typical refrigerator draws 725 watts, according to the United States Department of Energy. Divide that number by 120 volts, which is the voltage of your power supply, to get the current that the refrigerator draws in amperes. A 725-watt refrigerator draws 725/120 = 6 amps.

What size breaker do I need for a 1/2 HP well pump?

For a 1/2 HP submersible pump, a 15 amp 2 pole breaker would be normal. You can run 12 AWG, but unless the run is very long, 14 AWG is sufficient. Bigger wire would let you switch to a bigger pump later if you wanted.

What size generator do I need to run a refrigerator and freezer?

For example, if you want a generator to run a refrigerator and a freezer, the wattage (table 2) of the refrigerator would be 800 and the freezer would be 1,000. To select the correct size generator, you decide if both refrigerator and freezer are to start at the same time. If so, you would need (1,800 X 4) 7,200 watts.

How many amps are in a horsepower?

Given horsepower and volts, it is possible to calculate amps. The calculation of amps uses Ohm's Law, which is amps times volts equals watts. Multiply the horsepower by 746 watts. For example, an engine at two horsepower with 230 volts would be calculated as two horsepower times 746 watts, which equals 1492.
