How to use safely

1. Before any work, identify the circuit and switch the disconnect to OFF to establish a safe baseline.
2. Apply a padlock and tag as part of your lockout/tagout procedure to prevent accidental restoration of power.
3. Confirm the circuit is de-energized using appropriate testing equipment before beginning maintenance.
4. After work is complete and all checks pass, remove the lockout/tagout devices and switch the disconnect back to a ready state only when it is safe to re-energize.

Maintenance and care tips

• Inspect the handle and linkage for smooth operation and signs of wear; lubricate as recommended by your facility's maintenance guidelines.
• Keep the enclosure clean and free of dust and debris to maintain reliable isolation and operator visibility.
• Document routine checks and align with local electrical codes and safety standards to ensure ongoing compliance.
