4. Setup & Installation

Before beginning installation, ensure the power to the circuit is OFF at the service panel. Use a voltage tester to confirm the power is off.

4.1 Wiring Diagram Overview

The Eaton TR274W is designed for various wiring configurations. The device typically has brass screws for hot (line/load), silver screws for neutral, and a green screw for ground. Terminal screws are pre-backed out for convenience.

Common Wiring Configuration (Switch Controls Receptacle):

1. Connect the incoming hot (black) wire to one of the brass screws.
2. Connect the outgoing hot (load) wire to the other brass screw.
3. Connect the incoming neutral (white) wire to one of the silver screws.
4. Connect the outgoing neutral (load) wire to the other silver screw.
5. Connect the ground (bare copper or green) wire to the green grounding screw.

Independent Wiring Configuration (Switch and Receptacle operate independently):

For configurations where the switch controls a separate load and the receptacle is always hot, or if you want the neon pilot light to only illuminate when the switch is ON and controlling the receptacle, internal jumpers may need to be modified. Consult a qualified electrician or refer to specific wiring diagrams for advanced configurations. Some installations may require breaking a small metal tab between the hot terminals and adding a jumper wire to achieve desired functionality, such as having the neon light only illuminate when the switch is active and controlling the receptacle.

4.2 Installation Steps

1. Turn Off Power: Locate the circuit breaker or fuse controlling the outlet you are replacing and turn it OFF. Verify with a voltage tester.
2. Remove Old Device: Carefully remove the existing wall plate and device from the electrical box. Disconnect the wires.
3. Prepare Wires: Strip approximately 1/2 inch of insulation from the ends of the wires if necessary.
4. Connect Wires: Follow the appropriate wiring diagram for your desired functionality. Securely connect the wires to the corresponding terminal screws on the TR274W device. Ensure no bare wire is exposed outside the terminals.
5. Mount Device: Gently fold the wires into the electrical box and secure the TR274W device to the box using the mounting screws provided.
6. Install Wall Plate: Attach the decorative wall plate (sold separately) over the device.
7. Restore Power: Turn the power back ON at the circuit breaker or fuse box.
8. Test Functionality: Test the switch and receptacle to ensure they operate correctly.

5. Operating Instructions

5.1 Toggle Switch Operation

The toggle switch functions as a standard single-pole switch. Push the toggle up to turn the connected load ON, and push it down to turn the load OFF. When the switch is in the ON position, the integrated neon pilot light will illuminate, providing a visual indication of its status.

5.2 Tamper Resistant Receptacle Operation

The tamper-resistant receptacle features internal shutters that block access to the contacts unless a two-pronged or three-pronged plug is inserted simultaneously. This design helps prevent accidental insertion of foreign objects. To use the receptacle, firmly insert a standard electrical plug into the openings. You may feel slight resistance due to the shutters; this is normal. Ensure the plug is fully seated for proper contact.

6. Maintenance

• Cleaning: To clean the device, ensure power is OFF at the circuit breaker. Wipe the surface with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Inspection: Periodically inspect the device for any signs of damage, loose connections, or discoloration. If any issues are observed, turn off power and consult a qualified electrician.
• The thermoplastic construction is designed for long-term durability and requires no special maintenance beyond cleaning.

7. Troubleshooting

• No Power to Receptacle/Switch:
  • Check the circuit breaker or fuse for the circuit. Reset if tripped.
  • Verify all wiring connections are secure. Loose connections can interrupt power.
• Neon Pilot Light Not Illuminating:
  • Ensure the switch is in the ON position.
  • Confirm the device is receiving power.
  • If the light still does not work, there might be an internal fault, or the wiring configuration does not support the light's intended operation (e.g., if a jumper tab was broken for independent operation).
• Difficulty Inserting Plug into Receptacle:
  • This is a characteristic of tamper-resistant receptacles. Ensure the plug is aligned correctly and inserted with firm, even pressure.
  • Avoid forcing the plug, as this can damage the shutters or the plug itself.
• Switch Not Controlling Receptacle (or vice-versa) as Expected:
  • This indicates a wiring configuration issue. Review Section 4.1 "Wiring Diagram Overview" and consult a qualified electrician if necessary. Internal jumpers may need adjustment.
