3.2. Testing GFCI Receptacles
- First, perform a standard wiring test as described above to ensure the receptacle is correctly wired.
- If the wiring is correct, press the GFCI test button on the Extech ET11 tester.
- A working GFCI outlet should trip, cutting power to the receptacle. The GFCI reset button on the outlet should pop out.
- If the GFCI does not trip, it indicates a fault with the GFCI mechanism or wiring.
- To restore power, press the reset button on the GFCI outlet.
3.3. Interpreting Indicator Lights
The Extech ET11 features a clear light legend on both the front and back to help interpret wiring conditions. The legend uses combinations of three indicator lights (typically amber/orange) to show the status.
