The kVA rating on transformers defines the load carrying or power capability and stands for kilovolt-amperes. NEMA, the National Electric Manufacturers' Association establishes standards for distribution transformer kVA ratings.
The kVA rating of most transformers is generally marked on the outer enclosure.
