What it represents
A knife-disconnect terminal opens its circuit path using a documented pivoting knife element. The schematic records the separable connection and the terminal plan identifies the selected physical terminal.
How to read it
- Follow the knife element rather than assuming every terminal level opens together.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- Show opened path
- State normal knife position
- Reference terminal model
A distinction that matters
A visible knife disconnect differs mechanically from an isolating plug terminal.
