Hotsprings Electrical Question, Electrical Hook-up

[kevinv18]

In preparation for getting a spa, I have installed a 60A breaker sub-panel approximately 6 feet from where I intend to put the spa. I talked to a Sundance dealer who told me that the Optima spa requires only 3 wires into a 60A breaker. Then I talked to a Hotsprings dealer who told me that their Grandee spa comes with a sub-panel, which includes a 20A breaker and a 30A breaker. The pump wires hook up to one breaker and the heater wires connect to the other breaker. If I decide on a Hotsprings spa, then I will need to swap out the sub-panel that I spent considerable time installing. Or I could install the new sub-panel in series with my current sub-panel, but then I'd have two "ugly" boxes in my yard.

Can anyone confirm whether the Hotsprings Grandee requires two breakers (20A & 30A) or will the 60A breaker be sufficient by itself?

Thanks.

You would need the sub panel that comes with the spa.

Download the predelivery guide which has the wiring diagram.

If you followed the wiring diagram for the Sundance Optima, you ran 2 "hot" conductors and a ground conductor to that 60 amp panel.  Sundance uses a transformer to power things like the lights, radio, etc, that run on less than 240 volts, so there is no need to run a neutral leg to the spa.
 Hot Springs may (or may not) require a neutral.  
You may have to totally re-wire this.  Especially if HS requires a neutral.

That's why you have to decide on a spa before you run your wiring.  Most (but not all) require a standard 4 wire 50 amp configuration.  Many Sundace spas use the 3 wire configuration, Cal Spas had or had specific requirements for some of their spas too.
