Anyone aware of any regulations requiring the utility to provide short circuit current for utility supplied transformers? My utility is telling me they are too busy to provide such data and to just use the "infinite bus" method. Thanks. |

We have attached several items to our utility data sheet in the attempt to educate them in the importance of having accurate utility data. See https://webstore.ansi.org/standards/nema/nemaabp102015 Also see the last 6 pages of our utility data sheet that I have uploaded to the forum.
