Guidelines for transformer application designs. | EC&M transformers used in commercial and industrial facilities fall in the middle ground, and they usually have ratings between 250kVA and 1000kVA. On larger projects, they can go up to 10MVA. Because these transformers represent the majority, you should evaluate them carefully before choosing a unit for a specific project and/or application.
