4. Setup and Installation
Follow these steps for proper installation of your GFCI outlet:
- Turn Off Power: Locate the circuit breaker or fuse that controls the outlet you are replacing or installing. Turn off the power completely. Verify power is off using a voltage tester.
- Remove Old Outlet (if applicable): Unscrew and carefully pull the old outlet from the wall box. Disconnect the wires, noting which wires were connected to the LINE terminals and which to the LOAD terminals (if present).
- Identify Wires:
- LINE Wires: These wires bring power from the circuit breaker to the GFCI. Typically, these are the wires entering the electrical box first.
- LOAD Wires: These wires carry power from the GFCI to downstream outlets or devices, providing GFCI protection to them. If there are no downstream outlets to protect, the LOAD terminals will not be used.
- Ground Wire: Bare copper or green insulated wire.

Figure 4.1: Rear view of the GFCI outlet, indicating the LINE and LOAD wiring terminals. The LINE terminals receive power from the circuit, while LOAD terminals provide protection to downstream outlets.
- Connect Wires:
- Strip approximately 1/2 inch of insulation from each wire.
- Connect the LINE (hot) wire to the brass LINE terminal and the LINE (neutral) wire to the silver LINE terminal. Ensure a secure connection.
- If protecting downstream outlets, connect the LOAD (hot) wire to the brass LOAD terminal and the LOAD (neutral) wire to the silver LOAD terminal. Do not connect LINE and LOAD wires to the same set of terminals.
- Connect the ground wire to the green ground screw.
The Tri-Drive wiring screws are backed out and staked for easier installation.
- Mount the GFCI: Carefully push the wired GFCI outlet back into the wall box. Secure it with the provided mounting screws.
- Install Faceplate: Attach the color-matched midi-size wallplate using the captive screws.
- Restore Power: Turn the power back on at the circuit breaker or fuse box.
- Test the GFCI: Perform the initial test as described in the Operating Instructions section.

5. Operating Instructions
Your GFCI outlet is designed for continuous ground fault protection and features automatic self-testing.
5.1. Test and Reset Buttons
- TEST Button: Press this button to simulate a ground fault and trip the GFCI. The power to the receptacles will be cut off.
- RESET Button: After the GFCI has tripped (either manually or due to a fault), press this button to restore power.
5.2. Indicator Lights (LEDs)
The device features LEDs to indicate its status:
- Green LED: Indicates that power is present and the GFCI is functioning correctly.
- Orange LED: Indicates that the device has reached its end-of-life and should be replaced.
- Red Flashing LED: Indicates that device protection has been lost. The GFCI should be replaced immediately.
6. Maintenance
Your GFCI outlet performs automatic self-testing. However, it is recommended to perform a manual test monthly to ensure proper operation.
6.1. Monthly Manual Test
- Plug a lamp or other device into the GFCI outlet and turn it on.
- Press the "TEST" button on the GFCI. The lamp should turn off, and the GFCI's internal mechanism should trip, cutting power to the receptacles.
- Press the "RESET" button. The lamp should turn back on, indicating power has been restored.
- If the GFCI does not trip or reset properly, it may be faulty and should be replaced.
6.2. Cleaning
To clean the GFCI outlet and faceplate, wipe with a soft, damp cloth. Do not use abrasive cleaners or solvents.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| GFCI will not reset. | No power to the GFCI, wiring error, or internal fault. | Ensure power is on at the circuit breaker. Check wiring connections (LINE/LOAD). If power is present and wiring is correct, the GFCI may be faulty and needs replacement. |
| GFCI trips frequently. | Ground fault in connected appliance or wiring, or overloaded circuit. | Unplug all devices from the GFCI and any downstream outlets. Reset the GFCI. If it holds, plug devices back in one by one to identify the faulty device. If it still trips with nothing connected, there may be a wiring fault or the GFCI is faulty. |
| Orange LED is illuminated. | GFCI has reached its end-of-life. | Replace the GFCI outlet immediately. |
| Red Flashing LED is illuminated. | GFCI protection has been lost. | Replace the GFCI outlet immediately. |
| No power to downstream outlets. | GFCI tripped, or LOAD wires are incorrectly connected. | Press the RESET button. Verify that the LOAD wires are correctly connected to the GFCI's LOAD terminals. |
