Transformer schedules include which of the following information?

Transformer schedules are essential documents that provide vital technical information about transformers used in electrical systems. This includes details such as KVA ratings, which indicate the transformer's capacity to handle the load, and voltages that specify the input and output voltage levels necessary for proper operation. Feeder sizes are included as they need to match the current capacity necessary for safe and efficient transformer operation, and the mounting type informs how the transformer will be installed within a given environment.

The other options, while important in different contexts, do not pertain directly to the specifics regarding transformers and their operational requirements. Room dimensions relate to physical space planning rather than transformer specifications. A breakdown of labor costs is more relevant in project budgeting and accounting rather than transformer functionalities. Wiring paths concern the layout of electrical circuits and their routing, which, while crucial in electrical design, does not specifically contribute to the details required in a transformer schedule.
