JUNCTION
Conductor connection junction
A junction indication marks a documented electrical connection between conductor branches.

ANSI/IEEE conductor junction symbol
IEEE-oriented junction dot marking a connection between crossing or meeting conductors on an ANSI-style schematic.
In plain English
What does ANSI/IEEE conductor junction mean?
In ANSI-style schematics a solid dot at the meeting of conductors indicates an electrical connection. Unlike some IEC practice, readers in this convention often treat any crossing without a dot as not connected and expect a dot even on tees, so the dot carries more weight than it does on IEC drawings.
A simple example
This is a convention-specific lookup. The geometry here is independently drawn to explain the connection; it is not a certified reproduction of the IEEE graphic. The dot only states continuity; the physical joint may be a terminal, lug or splice elsewhere.
What the drawings help you do
Read any undotted crossing as unconnected unless the legend says otherwise. Confirm the physical connection point on the wiring diagram. The junction dot shows connection; the ANSI crossing hop shows deliberately unconnected conductors.

- Terminal
- An identified point where a conductor connects.
- Schematic
- A drawing showing function and connections rather than physical appearance.

What it represents
In ANSI-style schematics a solid dot at the meeting of conductors indicates an electrical connection.

This is a convention-specific lookup. The geometry here is independently drawn to explain the connection; it is not a certified reproduction of the IEEE graphic. The dot only states continuity; the physical joint may be a terminal, lug or splice elsewhere.
How to read it
- Read any undotted crossing as unconnected unless the legend says otherwise.
- Confirm the physical connection point on the wiring diagram.
Information to show or reference
- Place a dot at every intended connection.
- Avoid dots on crossings that are not connected.
- Keep the dot size legible after reduction.
A distinction that matters
The junction dot shows connection; the ANSI crossing hop shows deliberately unconnected conductors.
