Can anyone here with a 2005 Sundance Optima

[johnvb]

tell me what the electrical nameplate rating is, at the 240v/50-amp setup? I'm assuming the motors would be rated in full load amps, the heater is watts.

The new spa/spa room is part of an 1800 sq. ft. addition to my house, which is still under construction. I upgraded to a new panel, along with new circuits for the addition.

Before I order the spa, I need to make sure I don't go over my 200 amp rating/calculations. (Or will make adjustments elsewhere)

Thanks, John

Sorry I don't have the rating info. you are looking for, but it may be available on the Sundance website- you can download the owners manual, which should give you a ballpark.  At the very least, just add in 50 amps in your demand load calc, and see where that gets you.
We have about twice your square footage, the Optima set at 60 amps, plus central air, and we are not even close to the 200 amps that we have service for.
However we do not have an electic dryer or range, but even if we did, we'd still be ok.  
Many people with older electrical service, say 100 amps or under need to upgrade for a spa, but I don't know of anyone with 200 amp service who has to.  Maybe if your entire home was electric- including heat.

 Thanks, I will give them a call and post the results here.

We are at a little over 170 amps now, with my current calculations. That includes multiple HVAC units, swim pool, electric cooking and laundry equipment, bath whirlpool tub, etc.

To give you an example of circuit/breaker ratings compared to actual electric loads used to determine service requirements. I have a 60 amp breaker going to a subpanel I installed, which goes to smaller breakers feeding the swimming pool pump, light, receptacle, (@100%) and also an outside heat pump unit (@125%).

60amps x 230volts = 13800 watts
The actual total wattage of all the above equipment is only 8300 watts, or @230volt = roughly 36 amps to calculate in the load.

Wow.  If you are already calc'd out at 170, the spa just might put you over.  I'd be curious to see where you end up.  And if you do upgrade your service, where do you go from 200?

 It will be a big deal to upgrade the service. What I will do is eliminate some of the other loads that are on paper but not yet materialized (like a second garbage disposal for the kitchen).

The calculations are for the inspector, so I will make it work (may have to do a little "Enron like" adjustments)
