Amps for 3 x 5 hp pumps?

[Bama]

Putting in a new electrical breaker box for La spa Paradise H-2.  It is 93" x 133" and has 3 pumps @ 5 horsepower each.  Anyone know if 100 amps or 200+ amps needed?
Thanks,
Bama

The Paradise draws about 43 amps at the most , as with the 3rd pump on the heater is disengaged. Good luck!

you do know that 5hp rating your talking about is brake HP right.
They are 2.5 cont HP.  To run all 3 jetpumps you need more than a 50 amp service....talk to your dealer and see............

Are you installing this breaker panel just for the spa-  connecting it into your existing main service panel?
 Or are you installing a whole new service panel for your entire home, and are asking what the size of your new electrical service into your home needs to be with this spa?
 With what you've posted, it's impossible to tell which one it is.  

If it's a whole house panel you're asking about, you can't just install a bigger capacity panel unless you have the feeds to your home evaluated and resized if necessary.
 
If it's just a spa panel you're installing, the required breaker isn't going to be anywhere near 100 amps (which is why I'm suspecting your asking about the main service panel vs a spa box).  Find out in your documentation what sized GFI breaker is required for your spa.  A very common requirment is 50 amps.  

In any case, based on your question and the way you asked it, it's evident that you may not posess the knowledge or skills to safely do this yourself.  Get a pro out there so you don't burn down your house or worse.

Your manual should tell you if you need a 50 or 60 amp circuit.  If you don't have it yet, ask your dealer.  As far as 100/200 amp service, there was a good discussion of the issues in the "In 'Shock' from Electrical Quote" thread.

I have an Artesian and it has 3 therapy pumps and a large circ pump and it does as spaman says - it turns off the heater if two pumps go on. I believe the most my spa draws is about 30 AMPS but it's been a while since I installed it.

I'm goin' to get Vinny's test kit and I'll stay out of this one.

cmon   30 amps running all 3 jetpumps?  Each jet pump is pulling at least 15 amps.....

My tub has a 4500 watt heater so it will draw less than someone elses. Like I said it's been a while but I kind of remember it being about 26 to 30 amps and it's on a 50 amp breaker, so we all know it can't excede 40 amps max  ! Maybe it was 36 amps and I didn't carry the 1.

What do I know anyway, I don't do this for a living!

There are 2 6 bhp pumps and a 3 bhp pump - half them for continuous - that's a total of 7.5 hp x 750 Watts/hp = 5625/220 = 25.57 amps ... ok maybe it's not half and maybe it should be 768 watts/hp but it's close! And my heater shuts off when 2 pumps are on. 4500/220 = 20.45 + (3x750)/220 = 30.27

Does that sound about right?

The numbers look about right, but I was surprised to read that the heater shuts down when a second pump is turned on.  At 30 amps draw on a 50amp circuit, it seems like they could toggle between the third pump and heater.

Your electric meter actually spins slower when you turn on a second pump!

It may and I could be wrong ... although I am geeky sometimes I just want to sit in the tub and enjoy vs wondering what will happen when I press this button.

My tub will heat to 1º above setpoint and start heating again 1º below it, now that summer is leaving I will be in the tub as the water cools down and heater kicks on ... I'll experiment!

Oh and just recently I found out which floor suctions go to which pumps!

Please do not share your methodology on that experiment!

I'm going to share it - I have size 13 feet!   They get in the way of everything. I have a Dell computer at work that I ripped the front bezel off because it got in the way of my size 13's.

I think the important thing here is to go with the manufacturer's instructions. If they say this spa can run on 50 amps, then you can wire it that way.
