Amp draw on 3hp Pentair Intelliflo at various RPMs

[Poolnewb105]

Hey guys, I was hoping somebody would be able to tell me what the amp draw is on a 3hp Pentair Intelliflo variable speed pump at 2000, 2400, 2600 and 2800 rpms. I know the power draw is based off of the plumbing but I'll take the more conservative figures.

My electrician is trying to determine how much power I will need from thr circuit the pump is on but without the pool being open for the season just yet, we're unable to tell.

Thank you very much!

105,

I can't really help much, but the IntelliFlo uses a 20 amp breaker.. Unless there is some weird issue you are trying to work around, I would power it with a 20 amp feed.. I'm sure I just don't understand what your electrician is trying to do...

Thanks,

Jim R.

Trying to figure out what the continuous load is from this pump at the aforementioned rpms. We need to upgrade the wire size going to thr sub Pannel and are trying to determine if #4 wire would be adequate.

I know the max draw for this pump is 16A but I'm thinking with my pool at the rpms mentioned it must draw no more than 8A. Correct me if I'm wrong.

3 hp is 2247 watts
2247/220 is 10.2 amps
Add 20% for inefficiency 12 amps (probably not needed)
20 amp breaker with only the pump on it, 30 amp if your going to run something else with it.
Wire size also needs a footage number, there are charts

You only size the wire for max load, if your electrician really couldn't figure this out I don't think it's a good idea using him.

Here is a chart I made for my Jandy 3hp pump. Probably similar.

So if I understand correctly , at 2800roms it's 1200 watts which translates to 5.2A at 230v right?

Actually I would be a bit concerned about an electrician asking this question. Is this an actual certified electrician or a friend?

Roughly, yes. My pump actually real time has circuitry that calculates watt draw.

@Poolnewb105 find a new electrician. The one you have doesn’t know Code or what he is doing. You size the electrical for the max case, not on usage. Even if you use 8 amps, you size it for the nameplate draws.
That said, we would need to know system pressure at those speeds to give you an accurate answer on power consumption (and amp draw).

He's an electrician and a friend but was trying to see if he could make the existing 1in conduit work without digging a new trench. Biggest wire we could pull is #4 150ft from the main.

Ok that's great! Using this calculator:

Wire Size Calculator

10 copper or 8 aluminum

Bigger is better

I have a 70amp breaker going to my pool subpanel. The electricians used 1" gray pvc conduit for the 125' run. My 2.7HP pump is on it's own 20amp breaker.

Here are some numbers from my Intelliflo VS 3 hp.

1800 rpm = 408 watts
2800 rpm = 1530 watts
3250 rpm = 2317 watts

What gauge wire running out there and do you have a heat pump?

Awesome, thanks.

Sorry don't know what wire gauge they ran. I know it passed city inspection. No heat pump either, but I can handle the load if i choose to add a heat pump later down the road.
