What it represents
A high-current terminal provides a documented connection for large conductors and power circuits. Its schematic identifies the power path while the schedule specifies connection capacity and ratings.
How to read it
- Read the permitted conductor arrangements from the selected terminal data.
- 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
- State current/voltage rating
- Reference conductor range
- Identify terminal and lug arrangement
A distinction that matters
High-current rating does not make the terminal a switching device.
