Cross-Reference
Applications
- Use it for security system wiring where multiple conductors are needed for signaling and control.
- Install it in intercom/PA systems that require organized multi-conductor runs.
- Choose it for audio/speaker connections in building systems where consistent identification and tracking are helpful.
- Apply it to power-limited controls for indoor circuits that benefit from clear footage marking during installation.
