Ok, I have another question. Aren't the Neutral and Ground bonded in the main panel?
Yes

Generally yes they are. If you open you panel and look at the wiring you will see that neutral and ground are delivered from 2 separate bus bars. The neutral is the line being delivered from the power company. Ground is developed within your home.Ok, I have another question. Aren't the Neutral and Ground bonded in the main panel?
IF your outlet is indeed a "spare" dryer outlet - the answer is Yes. Is certainly be done. Three wire dryer outlets provide 240V and Neutral to the dryer.
Clothes dryers are 120V/240V devices. Power supplied to them using a 3 wire power feed are wired as hot, hot and neutral. The wire used at that time appear as you describe but it is actually "two hots and an unshielded neutral"

HOLY COW! Finally an answer to a question I posted a year ago. As long as I have it wired like a dryer outlet (its wired to a 2 pole, 30A breaker), I can use this existing wiring for my planned system. Every one in that thread was telling me the bare was a ground, nobody mentioned an un-shielded neutral... Thank you!!
but not bonded in a sub panel as a rule, at a sub panel if I can I like to drive in a ground rod
I have heard that as well. Why is that? Or can you point me towards some reading material? Or even a set of "search terms" on google? I don't mind looking things up and reading on my own but I don't quite know where to start.
Sub panel is only required to have grounding electrode (rod, plate, pipe... Depends on what is accepted where you live based on the soil) if it is a detached building.
Modern dryers have 4 conductors because they need a neutral for the 120 volt components in the dryer. 240 doesn't need a neutral but should have a grounding conductor. Older dryers have two hot and a grounding conductor,everything was 240 volts.
For heating elements that are 240 volt there is no "neutral" conductor. A grounding conductor is highly recommended for safety!
So, for anything that is strictly 240 volts, only 3 conductors are needed (verify this with your electrician before proceeding).
What is the H-H-G wiring set up for? If it truely H-H-G to the spa panel, you will not have a neutral. So the panel will only serve as a 240V power source. (In my opinion.) Now if it is old wiring and the circuit is set up for a dryer outlet (H-H-N) you will luck out.How do I wire a H-H-G to the spa panel?
With that set up you do not have a neutral.The wiring is currently setup for an electric car and I am sure that it is H-H-G. The only things this will power are the two elements. So I assume that I just wire the two hots in/out of the spa panel and make sure that the panel is also grounded, does that sound right? Or should I tie the ground into the neutral inside the spa panel?
Yes.Ok, so wire the hots in/out of the gfci breaker and I am all set to have my two elements be gfci protected?
Yes.
It will function just as well with that connection on the grounding conductor.According to Seimens GFCI wiring datasheet:
Note: A load neutral is not required on the circuit.
However, the white line neutral (pigtail) must be
connected to the panel neutral for the device to
function.
Based on this statement there must be a neutral connection between the panel and the GFCI breaker in order for it to work.
What ever. Apparently you are the expert..False a neutral and a ground are different neutral is the return path for the hots to carry unbalanced load so the will have voltage on them.

Yes but only at the first means of disconnect never again. A ground touching a neutral week trip a afci breaker. It's considered a fault.
Untrue......neutral is the return path for the hots to carry unbalanced load so the will have voltage on them.
What???It's manly if you share neutrals or have fluorescent lighting the neutral will have voltage if you hold both neutrals to complete the path it will zap you.
