Hi,
I just picked up a Hayward Heat Pump For our Swimming pool, I was hoping someone could give me a few tips on installing it. Here is the model number we got. http://www.inyopools.com/Products/02200014058160.htm

I will include a layout of what I want to purchase insofar as the wire needed for this device and also a pic of the name plate on the device.

I'd like to know if the breaker 50 amp Double Pole is the correct size based on the nameplate. It is a little confusing. I would also like to know if the type of wire picked out is correct kind.

Lastly what size liquid conduit (whip) do i need to hold 2 thhn # 6 and 1 # 10?

Here is the layout of what I want.

I have a 50 foot run from my main panel to a junction box on the outside of my house, I was planning on using W/G NM-B Wire Black # 6/2

I have a 65 foot run from the junction box above to the disconnect 50 or 60 amp box located by my pool. I wanted to use 6/2 UF-B Wire w/ Ground

From the disconnect box I have a about a 10 foot run and was going to run #6 THHN red and black and a #10 green inside a Whip. I think the total wire length would be a max of 15 feet from the disconnect.

I also have to bond all this to my pool and pump and heater I was going to use a number 8

Once again please advise on what I have here and I have included a couple pictures to help explain everything a little more.

Let me know if you need more information.
Thank You, Mike

You will need to tell people where you are from; regulations for pool related stuff has different requirements in each area regardless of what the CEC or NEC states.

The NM in the building is OK but as soon as it's outdoors pool equipment is required to have an insulated ground wire by Code (UF doesn't). Use PVC conduit and individual THWN wires.


**You don't need to run the #6 on the outdoor portion because #8 is rated at 50A in conduit due to their different temperature ratings.
(2-#8s and a #10 ground)

Wow, so if I can use #8 on the outside. I guess that means I can use # 8 on the inside as well (NM).
The name plate was a bit confusing reading it with a max breaker size of 70 amp then it said recommended breaker 50 amps. (Name plate shown in main post.)

So Just to confirm:
50 feet NM # 8 from main panel to Outside Junction.
65 feet from outside junction box - THWN, (The wire I picked out said it rated for both THHN and THWN?)2 # 8 and # 10 in 3/4 inch conduit to a 60 amp disconnect.
from the disconnect run to the Heat pump in a 3/4 whip using same wire as above.

Lastly does the bonding part look correct as well?
Thanks for your advice
Mike

#8 NM is limited to 40 amps.

#8 NM is limited to 40 amps.

Thanks, Jim. I'm confused now. So # 8 is 40 amps on the inside and 50 amps on the outside because of the temp rating of the wire.

I need to regroup. lain:
If I run #6 the entire run then I should be fine then, correct? I just need to change wire types on the outside.

When it comes to integrating THHN wire into your project, it is important to understand that THHN is UL listed with a rated 90 degrees Celsius in dry locations or 75 degrees Celsius in wet applications with a THWN rating. All of our THHN wire carries a dual rating on the cable marked THHN / THWN-2 for both the wet and dry temperature rating.

Thanks for your time, Mike

too bad you are not in canada, you could run teck cable all the way without any junction to the disconnect. In us i would try to use equivalent cable (mc with pvc jacket)
