ANSI single receptacle outlet plan symbol
US-style plan symbol for a single convenience receptacle: a circle with one line through it on the wall.
In plain English
What does ANSI single receptacle outlet plan mean?
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.
A simple example
Single receptacles are typically dedicated outlets for an appliance such as a refrigerator or a piece of equipment that must not share the outlet. Mounting height, NEMA configuration and circuit number are written beside the symbol or in a note.
What the drawings help you do
The symbol does not tell you the NEMA configuration or whether the outlet is tamper-resistant. The receptacle schedule and code notes provide those details.
This particular reference
US-style plan symbol for a single convenience receptacle: a circle with one line through it on the wall. The ANSI duplex receptacle uses two lines through the circle; the single form uses one.

What it represents
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.
Single receptacles are typically dedicated outlets for an appliance such as a refrigerator or a piece of equipment that must not share the outlet. Mounting height, NEMA configuration and circuit number are written beside the symbol or in a note.
The symbol does not tell you the NEMA configuration or whether the outlet is tamper-resistant. The receptacle schedule and code notes provide those details.
How to read it
- Compare the line count: one line through the circle for a single receptacle, two for a duplex.
- Look for subscript letters that modify the type, such as WP or GFCI.
Information to show or reference
- State NEMA configuration and rating.
- Tag panel and circuit number.
- Note tamper-resistant or dedicated use where required.
A distinction that matters
The ANSI duplex receptacle uses two lines through the circle; the single form uses one.
