4. Setup
- Inspect the Cord: Before plugging in, visually inspect the entire extension cord, including the plug, GFCI module, and outlet, for any signs of damage. Do not use if any damage is observed.
- Plug into Receptacle: Insert the male plug of the GFCI extension cord into a standard 120V AC, 3-prong grounded electrical outlet.
- Verify Power: The LED indicator on the GFCI module should illuminate, indicating that power is present and the GFCI is ready for use.
- Perform GFCI Test: Before connecting any device, press the 'TEST' button on the GFCI module. The LED indicator should turn off, and the 'RESET' button should pop out, indicating the GFCI has tripped.
- Reset GFCI: Press the 'RESET' button to restore power. The LED indicator should turn back on. If the GFCI does not trip or reset as described, do not use the cord and contact customer support.
- Connect Device: Once the GFCI is confirmed to be working, plug your device into the GFCI outlet.
5. Operating Instructions
The ELEGRP GFCI extension cord is designed for simple operation with its automatic reset feature. However, regular testing is crucial for safety.
- Normal Operation: When plugged in and reset, the LED indicator will be lit, signifying that power is flowing through the GFCI and it is providing ground fault protection.
- GFCI Trip: If a ground fault is detected, the GFCI will automatically trip, cutting off power to the connected device. The LED indicator will turn off, and the 'RESET' button will pop out.
- Automatic Reset: This GFCI features an auto-reset function. When power is restored after an interruption (e.g., power outage), the GFCI will automatically reset itself to the 'ON' position, and the LED indicator will light up.
- Manual Reset (after a trip): If the GFCI trips due to a ground fault, disconnect the device, press the 'RESET' button to restore power, and then reconnect the device. If it trips again, there may be an issue with the device or the circuit.
- Testing the GFCI:
- Plug the GFCI extension cord into a live receptacle. The LED indicator should be ON.
- Press the 'TEST' button. The LED indicator should turn OFF, and the 'RESET' button should pop out.
- Press the 'RESET' button. The LED indicator should turn ON.
- If the GFCI fails any part of this test, do not use it.
6. Maintenance
Proper maintenance ensures the longevity and safe operation of your GFCI extension cord.
- Regular Inspection: Routinely check the cord for any signs of wear, cuts, abrasions, or damage to the insulation, plug, or GFCI module.
- Cleaning: Disconnect the cord from power before cleaning. Wipe the cord and GFCI module with a damp cloth. Do not immerse in water or use harsh chemicals.
- Storage: When not in use, store the extension cord in a dry, cool place, away from direct sunlight and extreme temperatures. Coil the cord loosely to prevent kinks and damage.
- Avoid Sharp Objects: Keep the cord away from sharp edges, hot surfaces, and moving machinery.
7. Troubleshooting
If you encounter issues with your GFCI extension cord, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| GFCI trips immediately after pressing RESET or plugging in. | Ground fault in the connected device or the circuit. | Disconnect the device. Press RESET. If it holds, the device is faulty. If it still trips, the circuit may have a fault. Consult a qualified electrician. |
| No power, LED indicator is off, and RESET button is not popped out. | No power from the wall receptacle or internal damage to the cord. | Check the wall receptacle with another device. If the receptacle has power, the extension cord may be damaged. Discontinue use. |
| GFCI does not trip when TEST button is pressed. | GFCI malfunction. | Do not use the cord. Contact customer support for assistance. |
| LED indicator is off, but power is present (e.g., device works). | LED indicator malfunction. | While the GFCI may still be functional, a non-working indicator can be misleading. Contact customer support. |
