Thanks, Snoonyb and kaktuskid. 240 volt potential shouldn't be an issue if I connect both breakers to the same bus, right? I'm trying to avoid 240 to the tub jbox and, more importantly, to avoid 240 to the control box in the tub which coordinates the water pump and blower motor functions. Still leery of how the control box can "communicate" with both 120v. motors safely at the same time if those devices are on separate buses. If I use a DP breaker with a link rod, then I'll have 240 going to the 2 gang GFCI box in the bathroom wall and then 240 at the jbox with receptacles under the tub skirt. I suppose the separate 12/2 runs is the best bet, then. Snoonyb, I think your suggestion requires BOTH buses to acheive the advantage of the differential load on the neutral wire, is this correct? If 12/3 with the hots wired to 2 breakers on the SAME bus is used, would the resulting load on the neutral be the sum of the load on the two hots? If so, this would be overloading the capacity of the 12 ga. neutral. The run is short, around 30 feet, but I had a devil of a time just getting my fish rod up through the cables at the panel and into the attic. With such a tight fit, I was hoping to be able to pull one cable instead of two. Thanks again for your thoughts, folks.
