Why We Need GFCIs?
What is a GFCI?
A GFCI receptacle is different from conventional receptacles. In the event of a ground fault, a GFCI will trip and quickly stop the flow of electricity to prevent serious injury.
Definition of a ground fault:
Instead of following its normal safe path, electricity passes through a persons body to reach the ground. For example, a defective appliance can
cause a ground fault. A GFCI receptacle does not protect against circuit overloads, short circuits, or shocks. For example, you can still be shocked if you touch bare wires while standing on a non-conducting surface, such as a wood floor.
