Installation Instructions

Follow these steps for proper installation of the RACO 688 1-Gang Masonry Box:

1. Prepare the Opening: Create a rectangular opening in the masonry wall that matches the dimensions of the box (3-3/4 in. x 1-15/16 in. for the face, with a depth of 2-1/2 in.). Ensure the opening is clean and free of debris.
2. Select Knockouts: Identify the appropriate TKO knockouts for your conduit or cable entry. Use a screwdriver or knockout punch to remove the desired knockouts.

4. Position the Box: Insert the masonry box into the prepared opening. Ensure it is flush with the finished surface of the masonry.
5. Secure the Box: Use appropriate fasteners (not included) to secure the box firmly within the masonry. The rugged welded design ensures stability during this process.
6. Gangable Feature (Optional): If installing multiple devices, align additional RACO 688 boxes side-by-side. The gangable design allows them to connect securely, creating a continuous enclosure for multiple devices.
7. Wiring Connections: Make all necessary electrical connections inside the box. Utilize the forward-mounted grounding provision for easy attachment of grounding pigtails. The internal device ears prevent mortar from interfering with device screw holes.

Operating Instructions

The RACO 688 1-Gang Masonry Box functions as a protective enclosure for electrical wiring and devices within masonry walls. Once properly installed and wired, it provides a secure and code-compliant housing for switches, receptacles, or other electrical components. There are no operational controls on the box itself; its function is passive, providing structural support and protection for the electrical system.

Maintenance

The RACO 688 1-Gang Masonry Box requires minimal maintenance once installed. Periodically inspect the box and any installed devices for signs of wear, damage, or loose connections. Ensure that cover plates are securely fastened to prevent dust and debris ingress. If any damage is observed, disconnect power immediately and replace or repair components as necessary by a qualified professional.

Troubleshooting

Most issues related to electrical boxes are typically associated with the wiring or devices installed within them, rather than the box itself. If you experience electrical problems:

• No Power to Device: Check the circuit breaker for a tripped breaker. Verify all wire connections within the box are secure and correctly terminated.
• Loose Device/Cover Plate: Ensure all mounting screws for the device and cover plate are tightened.
• Interference with Mortar: If mortar has entered the device screw holes, carefully clean them out before attempting to install a device. The device ears are designed to minimize this, but proper installation technique is crucial.

For any persistent electrical issues, always consult a licensed electrician.
