DEFINITION

Classification: 315/212

(under subclass 211) Systems provided with a transformer connected between the source of supply and at least one of the load devices for supplying electric current and/or potential to the load device.

SEE OR SEARCH THIS CLASS, SUBCLASS:

219, and indented subclasses, for single load device systems under subclass 209 provided with a transformer in the supply circuit of the load device and having a periodic switch in the primary circuit of the transformer.

254, and indented subclasses, for other plural load device systems provided with a transformer in the supply circuit of at least one load device.

276, and indented subclasses and the subclasses specified in the notes to the definition of those subclasses for other systems provided with a transformer in the supply circuit of the load device.
