Transformers and transformer installations are covered by which NEC article?

Transformers and transformer installations are addressed in a dedicated NEC article that covers how transformers are installed, where they can be placed, required clearances, cooling methods, enclosures, and protective provisions. This article applies to both oil-filled and dry-type transformers and the equipment connected to them, providing the specific rules that ensure safe and reliable operation. The other articles cover different subjects—grounding and bonding, emergency power systems, and power distribution in healthcare facilities—so they don’t govern transformers in general.
