Three-phase symbols
In system single-line diagrams, transformers are often depicted using the symbol for a single-phase air-core transformer. This representation does not necessarily mean the transformer is an air-core type or single-phase....

Ganged Switch Symbology
When a switch is used in a circuit, it may contain multiple sets of contacts or smaller internal switches. These internal switches are depicted individually on a schematic. Often, the...
