Yep, should run fine on 30A. Also, the load shedder lights should show you if it was shed. I'm sure you're probably aware of this, but the set point must be at least 2* below the ambient temp before #2 will start.
I've seen situations where the ambient temp warms up to 1* above the set point, #1 starts and just maintains that temp. It doesn't have enough cooling power to cool down to the set point, but is strong enough to prevent ambient from going 2* above set point. So, in that situation #2 never gets called and #1 runs forever. A few times I have bumped the stat down a degree or 2 to get #2 to start and then move it back up to the temp I want...
