Preliminary Short Circuit Study‐ VA Loma Linda Pharmacy

MTA was contracted by Rock Electric to perform a Preliminary Short Circuit Study for the VA Loma Linda

Pharmacy Building. This Preliminary Short Circuit Study was generated using estimated feeder lengths that were provided to MTA. The Wire Sizes used for this study were taken off of the Engineer of

Record’s Singleline Diagram. It should be noted that once the actual feeder lengths are installed in the field, this study will be updated and re run which may change the Available short circuit current at each piece of electrical equipment. It is highly recommended that the EOR review the available short circuit current values provided in this study for each Distribution and Panel board.

MTA found that the feeder sizes shown on the singleline for the UPS Input and Bypass feeds were undersized for the breaker size shown on the Singleline. MTA assumed that these feeders would be

Sized at #2 AWG since the breakers were to be rated at 90Amps the #2 wire was used for this preliminary short circuit study. If this #2 AWG wire is not correct please let us know and we will update this preliminary Short Circuit Study to the correct size.

Since the 12KV contribution was unknown MTA has used 25,000A (3phase) and 25,000A (Line to

Ground) at 12,470Volts. This value is SCE maximum published 12KV contribution.

Should you have any questions or concerns about this study please do not hesitate to contact me.

Thank You, Mark Thomas, PE
