![]() A testing device used on such GFCI outlet will show “open ground”, and it would not trip the device.Īny receptacles down the stream from it / protected by this GFCI, must have two labels on its face-plate: “GFCI Protected” and “No Equipment Ground”.īelow are the 2008 edition NEC (National Electrical Code) requirements for the GFCI without ground installations. So, in our “ GFCI without ground” case, those installed GFCI receptacles (if wired properly) will perform as required by code when tested with their push-buttons. The grounded person becomes the equipment grounding conductor, and the current going through them creates the imbalance that trips the GFCI. Lack of a grounding conductor is definitely a negative, but good thing about GFCI outlets is that: equipment grounding is not required for their installation and for the device to function properly. Whenever you’re replacing an electrical outlet receptacle in an area currently requiring GFCI protection, such protection must be provided by using a GFCI outlet receptacle or by protecting this particular circuit by a GFCI breaker – it’s mandatory. However, there are only two wires inside the electrical junction box – no ground, and no easy way to install additional conductor, which would provide grounding. You decided to replace an existing electrical outlet receptacle in your bathroom, kitchen, garage, etc. You might have an older house with electrical wiring that hasn’t been updated. ![]() There is a common misconception about GFCI without ground installations, so let me clarify it for you.
