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

IEEE / ANSI

ANSI single receptacle outlet plan symbol

In US architectural electrical plans a single receptacle is commonly drawn as a small circle on the wall line with a single line through it. The form is quick to draw and visually lighter than the IEC half circle, and it is placed with the circle against the wall where the device box is installed.

Drawing use: GA
Application: Installation & communications
Reference family: IEEE / ANSI
Form evidence: Single receptacle plan symbol. US architectural electrical plan practice in the ANSI Y32.9 lineage, read alongside IEEE 315 context; independently drawn, not a certified IEEE or ANSI graphic.

A distinction that matters

The ANSI duplex receptacle uses two lines through the circle; the single form uses one.

Drawing use: Schematic

Form evidence: Single power receptacle. Autodesk IEC-60617 Symbol Preview — Single and duplex power-receptacle forms; vendor family reference, not certified IEC geometry or database identifier.

A distinction that matters
