3. Setup and Installation
The Raco 205RAC Retro-Ring is designed for easy installation in existing walls. Always ensure power is OFF at the circuit breaker before beginning any electrical work.
Required Tools:
- Drywall saw or utility knife
- Screwdriver (Phillips or flathead, depending on box screws)
- Pencil
- Tape measure
- Voltage tester
Installation Steps:
- Turn Off Power: Locate the circuit breaker controlling the area where you will be working and switch it to the OFF position. Verify power is off using a voltage tester.
- Mark Opening: Using the electrical box as a template, carefully mark the desired location and size of the opening on the wall surface. Ensure the location avoids studs or other obstructions.
- Cut Opening: Carefully cut out the marked opening in the drywall or other wall material using a drywall saw or utility knife. Ensure the cut is clean and precise.
- Insert Wires: If not already present, feed the electrical wires through the newly cut opening.
- Attach Retro-Ring to Box: Slide the Raco 205RAC Retro-Ring onto the electrical box. The design allows it to clip securely to the box, providing the necessary support for old work installation.
- Insert Box Assembly: Carefully insert the electrical box with the attached retro-ring into the wall opening. The retro-ring's tabs will engage with the back of the drywall, securing the box in place as you tighten the box's mounting screws.
- Secure Box: Tighten the screws on the electrical box. As you tighten, the tabs on the retro-ring will pivot and clamp against the inside of the wall, pulling the box firmly against the wall surface.
- Wire Connections: Complete all necessary electrical wiring connections inside the box according to local electrical codes and device instructions.
- Install Device and Cover Plate: Mount the electrical device (e.g., outlet, switch) into the box and then install the decorative cover plate.
- Restore Power: Once all work is complete and verified, turn the power back ON at the circuit breaker.

Most issues related to the Raco 205RAC Retro-Ring arise during installation. Here are some common problems and their solutions:

- Confirm that the electrical box mounting screws are tightened sufficiently to pull the box firmly against the wall.
