I can run the A/C and the microwave at the same time. However if the water heater is set for electric and it comes on that will trip the breaker. Other things that could put you over 30 amps if they were on at the same time would be a toaster, hair dryer, coffee pot, electric space heater, large fan connected to an outside outlet or your battery is low and charging heavily.
