Portable GFCI - Ground Fault Circuit Interrupters 

A ground-fault circuit interrupter (GFCI) is the only protection device designed to protect people against electric shock from an electrical system. We offer a broad selection of portable ground circuit interrupters. 

A GFCI integrates a ground fault protection in receptacles where electrical equipment is near water or might be in contact with water.

Ground fault circuit interrupter also detects ground faults and interrupts the flow of electric current. A GFCI is not and might not be used to replace a fuse and does NOT protect against circuit overloads, short circuits, or shocks

The GFCI measures the amount of current flowing from hot to neutral, so the circuit can trip and shuts off. When properly installed, a GFCI can detect variations as small as 4 milliamps, and it trips quickly, less than a second, cutting off electricity.
