Side-by-side reference

Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

First referenceCompare with

AC 1PH

Symbols

Single-phase AC source

A single-phase AC source identifies a documented source boundary in a schematic or SLD. The source label and supply data explain what provides the circuit's voltage and frequency.

Drawing use: SLD / Schematic
Application: Microgrid systems
Reference family: IEC / Manufacturer

A distinction that matters

A source-boundary symbol is not a product-specific generator or transformer diagram.

GEN

Symbols

Generator

A generator representation identifies an electrical source in a power system. Its electrical connections and associated switching describe how it supplies the system. The equipment documentation establishes machine type, rating, voltage, earthing and operating capabilities.

Drawing use: SLD / Schematic
Application: Microgrid systems
Reference family: IEC / IEEE / ANSI

A distinction that matters

A generator symbol identifies an electrical source. It does not establish permission to parallel with another source or define the transfer sequence.
