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.

AC 1PH

IEEE / ANSI

ANSI/IEEE Single-phase AC source form

This reference locates single-phase ac source in Autodesk's IEEE-oriented miscellaneous family. 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. The public library uses HPW1_1PH for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.

Drawing use: SLD / Schematic
Application: Microgrid systems
Reference family: IEEE / ANSI / Manufacturer
Form evidence: Power Source 1 Phase. Autodesk IEEE Symbol Preview: Miscellaneous, block HPW1_1PH. Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier.

A distinction that matters

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