Jacuzzi J480 50A to 60A Conversion Question

[Tleo]

I just purchased a used, 2011 Jacuzzi J480 hot tub.  In getting ready to hook it up and run the electrical wiring, I can't determine whether the previous owner had it set to 50A or 60A configuration.  I have read people talk about the need to install a "jumper" but it doesn't appear that I have access to the electrical unit where a jumper would be located.  I have also seen people mention that it is now a "soft" setting that can be configured from the J1000 control panel.  I am hoping that someone can help me understand how to check this setting in the 2011 models so that I can ensure I run the right electrical wiring to the tub.

Thank you for your help.

TLeo -

I can't help with the jumper settings, but the good news is that your wiring requirements are the same for both a 50 and 60amp circuit.  6awg THHN run in RNM conduit will take care of things for you. Whether you need 3 or 4 wires is up to your tub's specific configuration. 

I tried to find a simple table for you, but this one should suffice:

Thanks, Sorebikr. The issue is that I already have s 50A breaker and 8G wire running to an existing tub so I am trying to figure out if I need to rewire the whole thing or just use the 50a setting. I am worried that if the previous owner had it set for 60A, it will keep tripping the breaker. I don't know how to check that, though, so hoping someone will be able to educateg me before I go and rewire the while thing.

The bad news for you is that if you want this done right, and up to code, you need to rewire it regardless.  Your wire is currently undersized. A 50 amp circuit requires 6awg wiring.

 The spa will accept 50 or 60 amp with out changing anything, I would recommend 60 amp.

Jim - his wiring is undersized, don't you agree?

[Tleo]

I think you are right about the 8 gauge wire.  I talked to an electrician today and he told me the same thing.  I guess that means I am going to need to run new wire either way.  I was hoping I wouldn't have to but I guess I will.  Hopefully that won't add too much to the cost.

I'm still confused about how you change the setting on the J480, though?  How do I configure it for 60A service?  Is it done via the installation of a jumper, via the control panel or will it just work automatically without me doing anything?  The owners manual suggests something needs to be done but I'm not sure exactly what that is.

Thanks for all the help!

  I would go with#6 as well.   As far as the setting you don't have to do anything, it will accept 50 or 60amp If it is the J1000 controller?  If its not then you will have to change it.

[Tleo]

It is the J1000 controller. Do I need to change a setting in the menu or will it adjust automatically?

Thanks again.

[Jacuzzi Jim]

  Should be fine on it's own.

What Jacuzzi Jim means, is that it will work, but it won't be calibrated correctly.  You need to set up the electrical preferences through the J-1000 control after all the electrical hook up is done.  For instance, if the spa was hooked up to a 50A before and you have a 60A now:

Spa will have power for either.  However, the Spa will not run the heater if both jet pump are on if it is set up for a 50A.  This is regardless of what power is coming into the spa, 50A or 60A.  That is why you need to set it up through the J-1000 control so you tell your spa to run the right power hookup.

Talk to your local dealer, they should be able to help you out.

Tleo, I can't comment on the 60a change except to say check out your dealer, they can do the change easily. What I can comment on is the tub itself. I have the J-470 model and it is awesome! People come over and all they can talk about is how nice it feels and how good the massage is. Very powerful in all seats, and the controls are located in good spots. It is a well thought out and well made tub. You will love it for years to come!
