If your unit is not running on 30 amps something is wrong with the ac or the wiring.
I witnessed my buddies future father-in-law plug his fathers camper into a 30 amp welder outlet (240v), hilarity ensued. By hilarity, I mean popping and smoking, followed by a lot of cursing.
That was an awkward moment.
This was before I owned a camper, I learned the difference between 30 amp 120v and 240v that day.
