What is GFCI?
All electrical circuits return to their earth ground unless something interrupts that cycle. When a human chooses to be a semiconductor and interrupt the flow, it causes an electric shock in the body. The circuit doesn’t know the difference between the cabling or device it is supposed to travel through and the interrupting human body!
In an attempt to make electrical devices safer and prevent most shocks, circuits can be GFCI protected.
GFCI stands for “Ground Fault Circuit Interrupt.” This type of protection is generally tied to a breaker or receptacle. The technology detects an imbalance in the current returning through the circuit to earth ground and interrupts or breaks the circuit by tripping and opening. This will shut down the flow of electricity and thus hopefully reduce the harm from or totally prevent a shock.
