ANSI/IEEE cable pothead symbol
IEEE-oriented pothead symbol marking a sealed cable termination where an insulated cable meets an overhead line or bus.
In plain English
What does ANSI/IEEE cable pothead mean?
Pothead is the traditional North American term for a sealed cable termination, especially at riser poles and outdoor substations. IEEE-style single-line diagrams show it where a cable rises to connect to an overhead line or open bus, often with a lightning arrester beside it.
A simple example
This illustration is an independent explanation of the convention and is not the IEEE graphic. Modern terminations may be porcelain, polymer or slip-on types, all of which may be called potheads on older drawings. Rating and creepage distance belong in the equipment data.
What the drawings help you do
Look for an arrester at riser pole potheads. Treat older pothead labels as any sealed termination type. A pothead is a fixed sealed termination; a separable connector can be unplugged.

How to read it
- Look for an arrester at riser pole potheads.
- Treat older pothead labels as any sealed termination type.
Information to show or reference
- Identify termination type and rating.
- Show associated arresters.
- Mark phase identification at the pothead.
A distinction that matters
A pothead is a fixed sealed termination; a separable connector can be unplugged.
