Dual A/C SHOULD come with 50A system
30A is OK for ONE 15K A/C unit provided you don't run water heater on electric or microwave when A/C is on etc.
30A service......1 hot leg with 3600W available
50A service.......2 hot legs each with 6000W availability total of 12,000W
So with 50A rig and using 30A service.....1 A/C at time and watch/manage the rest of AC components
Is it time for your medication or mine?
