- Identify the Incoming Live Wire: The ring should be installed around the incoming live wire that carries current into the electrical panel. This is usually the wire coming from the main breaker.
- Direction of Current Flow: Ensure the ring is oriented in the direction of current flow. The meter should measure the current as it flows through the wire into the panel.
- Consult the Installation Manual: Check the installation manual for specific instructions on the orientation of the ring. It often includes diagrams to help with proper installation.
- Verify with a Multimeter: If unsure, you can use a multimeter to confirm the direction of current flow and ensure the ring is installed correctly.
