User Attachable GFCI and RCD

GFCI (Ground Fault Circuit Interrupt), also known as GFI (Ground Fault Interrupters) and RCD (Residual Current Device), are safety devices which shut off an electrical power circuit when it detects that current is flowing along an unintended path. One example of an unintended path is through water or a person. GFCIs and RCDs are based on Kirchhoff's Current Law, stating that every point on a circuit must have exactly same current as all other points. Meaning, that if the hot line and the neutral line have different currents, the device is an abnormal condition and will trip, shutting off the circuit and stopping the flow of electricity. USER ATTACHABLE GFCIs allow you to connect the ground fault interrupter to an existing cable that has been ROJ'd (Remove Outer Jacket) and Stripped. These are commonly used to replace malfunctioning or broken GFCI's on existing equipment, or in custom engineering projects.
