As of June 29, 2015, revisions to UL 943 Standard for Ground Fault Circuit Interrupters (GFCI) go into effect. The changes aim to improve protection against serious injury, electric shock, and electrocutions.
Newly manufactured GFCI receptacles must include auto-monitor self-testing and power-denial end-of-life features.
Self-testing will identify any failure or malfunction and help protect against electrocution.
If a self-test finds the GFCI has reached its end of life, it will lock itself, deny power and prevent a reset.
HD Supply offers older GFCI models while supplies last, as well as the newer UL 943 Standard models.
