# Question: How Do I Know What AMP My Well Pump Is?

## What wire do I use for a well pump?

Southwire’s Submersible Pump cable is used submersible pumps in well castings as specified in the National Electrical Code.

It is made with 2 or 3 conductors with a bare ground.

The conductors are annealed soft copper, type THHN/THWN..

## Does a well pump need its own circuit?

Just like most motor-driven appliances like a furnace or air compressor, a water pump consumes increased electrical current as the pump motor starts. This start-up current can demand nearly all of the capacity for an electrical circuit and therefore requires its own dedicated circuit.

## Can a 4000 watt generator run a house?

## How many watts does it take to run a well pump?

700 wattsConsumer 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.

## How many amps is a 1/2 HP well pump?

5.0 ampsHow 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.

## How do I know what kind of well pump I have?

## Should a well pump be on its own breaker?

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.

## Do all well pumps have a control box?

Two wire well pumps do not use a control box. All the elements already come built within the motor or pump house itself. This allows for easier installation. However, if any of the starting components fail, the pump will have to be pulled up and the whole motor will have to be replaced.

## Why does my water pump keep tripping the breaker?

Question: well pump trips the circuit breaker Most likely the water Pump or its control or wiring is shorted or motor is failing and drawing high current. … The short could be in the motor, the pump control switch, or in damaged wires anywhere between house and your well pump motor.

## What size breaker do I need for a well pump?
