Answer 1

Effective June 29, 2015, all GFCI receptacles and circuit breakers must have an auto-monitoring (self-test) feature that automatically conducts a periodic internal test to confirm that the GFCI is able respond to a ground fault. If a problem is detected, the GFCI must trip and deny power or provide a visual and/or audible indication.

Green Status

Dual indicator:

• On initial installation - If no power to load, device has been wired incorrectly
• Normal operation - GFCI has passed self-test and is providing power

Red Status

• Blinking = Initial self-test upon first power up
• Solid or blinking = Press TEST and RESET buttons to reset GFCI
• If GFCI will not reset OR solid or blinking red continues, replace device

No Power

• GFCI in tripped state, no power

• Press RESET button

• If GFCI will not reset, no power on the circuit

Self-Test Indications: If the Status Indicator Light is solid or flashing RED a problem may exist. Press the TEST button to trip the GFCI. If unable to Reset, replace the GFCI.

NOTE: The status indicator may flash Red at power "ON" and Reset.
