Hello everyone,
I have been requested to provide a fault current for a new 400 Amp 3-position ganged meter base. The service will be fed from a 150kVA Open-Delta bank on a 7200/12470 Volt system consisting of a 100kVA lighter pot and a 50kVA power pot both with an impedance of 1.5% . The service will be fed with 1/0 triplex w a #2 reduced neutral approximately 75 feet long. The different fault calculators i have give me approx. 42,000 Amps at the secondary bushings of the transformer but I know it will be less at the meter base. Any help figuring this out is greatly appreciated. Thank you.
