Installing and testing GFCI Receptacle
Please read this leaflet completely before getting started
1. What is a GFCI?
A GFCI receptacle is different from
conventional receptacle. In the event of
a ground fault, a GFCI will trip and
quickly stop the flow of electricity to
prevent serious injury.
Definition of Ground fault:
Instead of following its normal safe
path, electricity passes through a
person’s 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.
