Thanks all, the spa is going to be to the right in the picture and will spill into the pool (it is a giant hole at this point). The control system I have is the Jandy Aqualink RS (PDA). Most of the time it will be just me and my spouse. I added a 3 way to the return line before the check valve coming out of the filter (before the heater) so that the main pump can supply the 1.5" to the spa (spillover and chlorinate if I move the salt gen.) while the 2hp pump heats the spa and supplies the jets. I have 2 Hayward pumps, both are "Northstars" 1hp & 2hp. With the setup this way I should be able to chlorinate the spa while using and if it gets to be too much can divert or just shut off the main pump. I probably am overthinking this but I don't want to be stuck with what I've got and not be happy with it once the decking is poured.

wow.... 10% down... our project was for $90,000... In California, Pool Builders are only allowed to collect $200.00 down and the rest in stages although most contracts seem to be front loaded when the consumer has to come up with roughly 50% of the job by the time gunite is completed. I think we paid $9000.00 or 10% after dig and $9000.00 after steel.. or 10%... another 27,000 or 30% after partial electrical and completed gunite. so we were into it for $45,000 and all we had was gunite. I know from talking to subs that the builder had only spent 2000.00 on dig and 3500.00 for steel and his gunite cost was 5500.00 and misc plumbing was 2500. not even complete plumbed out yet. so he was 13,500 out of pocket and I had already paid $45,000.00?? I guess they get their profit first before completing the job? who knows... our project also included an outdoor kitchen/bar and BBQ and fireplace with 2500 sq. ft of stamped and colored decking that was also into the price and was added to the individual payment program.. when the builder is building you much more than a pool, it is quite easy to feel you are on the wrong side of a front loaded contract.. the price of the Deck/BBQ/Bar/Kitchen/fireplace were all included in the intial payment plan.. yet the builder was not even close to even starting any of those items when we were 1/2 way thru with the payment plan. I feel your pain... good luck

Well, now we are just waiting for the Archetictural Review Board to review our plans. The ARB is kind-of a joke because we only have 3 houses in our neighborhood. Anyway, we went with a 7.5' spa. I though 7' was too small and 8' was too big. I "borrowed" some of all of your suggestions and ideas and went with all stone surround added a step, all Pentair and 400,000 btu. Still trying to decide on 7', but the ARB does not care about that. Thank you for all of your help! I'll post more pictures once we get started.

Typically, you would want anything on 220v on a double pole breaker. Those are the double wide ones with a bar connecting the 2 switches. From you description, it sounds like someone was trying to save space and use tandem breakers (single wide with 2 unconnected switches.) The problem with that is that the double pole breaker will trip both sides at once if there is a problem in either leg. Using 2 of these tandem breakers means that one leg can trip and leave the other live. If I had to take a wild guess, I'd guess the PV contractor moved 1 leg of your pump wiring up a slot and accidentally put it on the same phase as the other leg. There should be a diagram on your panel showing which slots are on what phase. The 2 for your pump need to be on opposite phases. Either way, it sounds like your original setup could use some improvements to bring it up to modern standards. I'd call an electrician and get a professional opinion.
