How to wire a pool pump

What size breaker do I need for pool pump?


Does a pool pump need to be grounded?

Insulated ground wire is required for grounding pumps. Making a mistake grounding and bonding a swimming pool pump can be deadly. Grounding enables faster circuit breaker action, and bonding ties conductive metal parts together so they have the same electrical potential. Together, both reduce the risk of fatal shock.

Can you wire a pool pump backwards?

don’t work if run backwards. I have seen such pool pumps where the impellor would unscrew if run backwards. Single phase AC motors direction of rotation is not determined by the wiring but by the side of the winding the start capacitor that every single phase induction motor has.

Is it OK to run pool pump 24 hours a day?

Ideally, you should run your pump for 24 hours a day, but we know that’s unrealistic (and pricey), so let’s look for an answer that keeps your pool clean and your wallet full. Generally running your pool pump for 12-hours a day is a good option. … For a residential pool the water should turn over at least once per day.

How many amps does a 1.5 HP pool pump draw?

In our example we used a 1.5HP Hayward Super Pump. The voltage rating is 115/230 and the amp rating is 18.6/9.3. If you run a pump on the lower voltage rating (115) you will select the higher amperage rating (18.6).

How many amps does a swimming pool pump use?

If you need to know the electrical requirements for your inground pool, here is a list of common pool equipment and the approximate volts and amps required for each: Pool Pump: 240v, 10amps. Salt Water Chlorinator: 240v, approx 5-8 amps. Pool Heat Pump: 240v, 50 amps.

How many amps does a 2 HP pool pump draw?

A 2 hp pump won’t pull twice as many amps as our 1 hp example motor UST1102, but it will be more, about 25% more, up to 20/10 amps.

Why does my pool pump trip the breaker?

It may be because of four reasons: Your circuit breaker is short circuiting from the water or corrosion collected by the pool pump. Debris from the rain goes into the housing, making the motor overwork. It can also be due to moisture from certain weather conditions as well.

How do I know if my pool is bonded?

“It’s a simple solution: properly bonding the pool.” Loden recommends going out to where your motor and pumps are to check for bonding. Look for an exposed copper wire attached to the motor and pumps, going into the ground. It should connect in a similar way as in the image to the left.

How do I bond an old pool?

Bonding Requirements for Existing Pools

  1. On an existing pool determine if there is a pool bond wire at the equipment pad. …
  2. If there is not a pool bond wire then drive a ground rod close to the equipment pad and connect all the equipment that has an external bond lug.

What happens if you don’t bond a pool?

The low impedance path back to the power source allows the harmful current to flow and trip the breaker at the panel. Without a bonding system in place, you might conduct stray electrical current when touching the metal pool rail or pool water.

What happens if you wire a pump backwards?

If your pump is wired improperly, you could be reducing flow by up to 70%. … If rotation is backwards, the impeller and acorn nut can spin off in just a few seconds, causing damage to the pump’s components such as the bearings or seals.

What happens if you wire an AC motor backwards?

Reversing an AC Motor

Since each wire consists of a positive and negative current within the magnetic fields, the flip-flopping of main and starter wires causes the motor to run in reverse rotation. This easy switching of wires works because the polarity of the magnetic field is reversed, thus reversing the motor.
