Explicación
A GFCI is a Ground Fault Circuit Interrupter that protects workers from electric shock by quickly shutting off power when it detects current leaking to ground. It reacts to very small imbalances in current in a fraction of a second. GFCIs are required for many temporary power and outdoor circuits on construction sites.
