MGM’s low voltage dry-type transformers (75KVA and below) are made to withstand reverse connections without a loss of KVA rating. However, reverse feeding a step-down transformer has several limitations which include but are not limited to:
1. Requirement for larger sizing on breakers
2. Increased inrush current
3. Incoming voltage tap settings will not be available
NOTE: It’s always best to purchase a specially designed and manufactured step-up transformer instead of reverse feeding a step-down unit.
