What is the formula to determine the current rating on a Transformer?

Issue:
How can you find out the current rating of a transformer?

Product Line:
LV Transformers

Environment:
Applies to Low Voltage Transformers by SquareD/Schneider Electric

Resolution:
For a three phase Transformer, divide VA rating (10 KVA = 10,000VA) of the transformer by the the load line-to-line voltage and by 1.732 (the square root of 3,).  For a single phase Transformer, divide KVA rating of the transformer by the the load line-to-line voltage.

Example: Three phase 10KVA = 10,000 /240/1.73 = 24A. for Single phase -  10,000/240 = 41.66A
