I've read through a lot of old posts and can't find exactly what I'm looking for.
I am installing a 2500 Amp three phase 120/208 Volt service for a new apartment complex in New Haven. The local utility (UI) is asking me to show that they will have no more than 10,000 AIC at their meter cans. They told me that I had the possibility of 200,000 AIC at the load side of their transformer that is located in their vault right outside the building. I spoke with my engineer and he had no idea what they were looking for. I called a second engineer and he did a calculation but he came up over 10,000 AIC because the software he used would not allow he to input all the variables in the service. He said he didn't have the software needed or the training in the better software to input all the information. I'm in a bind. If anyone can point me in the right direction I would appreciate it. I guess what I need at this point is a recommendation of a person or company who has this software and training. Or let me know where I can get the software for a reasonable price to try to do this myself. But I don't know if I would have to be an Engineer to be able to present this calculation to the local utility.
Thanks for your help.
