How To Replace An Old 2 Prong Outlet Using 3 Prong GFCI And Why GFCI Tester Won't Work 

Here I demonstrate how to replace an old 2 prong receptacle with a new 3 prong GFCI receptacle. This old-type of house wiring doesn't have a ground wire that newer houses come standard with.
This is why electricians use the GFCI-type of receptacle instead of the standard receptacle seen in any modern house. So if you don't want to re-wire your entire house, then using this GFCI outlet is the next best thing.
HERE ARE THE TOOLS AND GFCI OUTLET I USED IN THE VIDEO:
