There is not enough information provided in the message to size the service. You can download a free service size calcualtor from my website. Even with the calculator, more information is needed.

I turned on all three central A/C units, the electric dryer, all of the burners of the range top and the double-wall oven units, and the main popped.

If you think I am unqualified, then how many amps are allowed on a 150 amp main?

Gary,

Download my free electrical service size calculator. It will help you gain a better understanding of how services are sized.
