NOTE This standard has been superseded and is retained only for existing adoptions and revision history. (1.1)

NOTE The original scope combined low-voltage dry-type units and medium-voltage units in one standard; use-case-specific option lists ("(dry-type only)", "(pad-mounted only)") made a split the correct structure. (1.2)

NOTE Dry-type transformers rated 600 V and below (UL 1561, IEEE C57.12.01) are covered by Low Voltage Dry Type TransformersLow-Voltage Dry-Type TransformersResolves to the current adopted revision.sync/low-voltage-dry-type-transformers. (1.3)

NOTE Transformers with a primary voltage above 600 V — liquid-immersed pad-mounted units (IEEE C57.12.34) and medium-voltage dry-type units (UL 1562) — are covered by Medium Voltage TransformersMedium-Voltage Distribution TransformersResolves to the current adopted revision.sync/medium-voltage-transformers. (1.4)

NOTE Existing adoptions of this standard continue to function against their adopted revision; new projects should adopt the successor standards. (1.5)
