Thanks to everyone who replied. It is my sisters house and she and her husband are doing some remodelling, and the HVAC guys are installing the A/C 7 tons of it. and that comes out to 24500 VA or 102 amps of load since its A/C it has to be taken at 100 %, and the EC wants to put in a 300 amp service, and ironically enough they do live in Texas.
In light of that it looks correct. I understand that there are variables, and just wanted a ballpark to see if she was getting what she needed or getting ripped off.
So thanks again.
