ANSI/IEEE terminal with wire number symbol
IEEE-oriented round terminal that displays the wire number passing through it rather than a terminal number.
In plain English
What does ANSI/IEEE terminal with wire number mean?
The publisher's IEEE terminal preview lists a round terminal form that shows the wire number at the terminal. It is used where the wire identity is more useful to the reader than the terminal position, for example on field wiring sheets where technicians trace wires by number.
A simple example
This illustration is independent and not the IEEE graphic. The form does not show the terminal strip position, so the terminal plan is still needed to find the physical terminal. The wire number continues unchanged through the terminal in this form.
What the drawings help you do
Use the terminal plan to locate the physical position. Read the wire number as continuous through the terminal. This form shows the wire number; the ANSI numbered terminal form shows the terminal number.
This particular reference

- Terminal
- An identified point where a conductor connects.
- Schematic

What it represents
The publisher's IEEE terminal preview lists a round terminal form that shows the wire number at the terminal. It is used where the wire identity is more useful to the reader than the terminal position, for example on field wiring sheets where technicians trace wires by number.
This illustration is independent and not the IEEE graphic. The form does not show the terminal strip position, so the terminal plan is still needed to find the physical terminal. The wire number continues unchanged through the terminal in this form.
How to read it
- Use the terminal plan to locate the physical position.
- Read the wire number as continuous through the terminal.
Information to show or reference
- Keep wire numbers unique.
- Link to the terminal plan.
- Use the change form where the number changes.
A distinction that matters
This form shows the wire number; the ANSI numbered terminal form shows the terminal number.
