Installing a GFCI Outlet Without a Ground Wire Video

Hi Sam,
A separate ground wire sized appropriately for the circuit may be installed using methods in compliance with the NEC code from the electrical panel where the bonded ground system has been installed, and where the circuits originate. The ground wire may be installed out to the GFCI Outlets where the inspector is requesting a ground wire connection. Consult with the inspector for complete details regarding his request and any specific requirements in your local jurisdiction.
Thank you for sharing your GFCI outlet question with us,
Dave

Hi Sandi,
The tripping circuit breaker of the GFCI outlet and other outlets is most likely due to a problem with the wiring to the outlets or another problem within the circuit wiring. Installing a ground wire from the GFCI outlet ground screw to the mounting screw of the outlet really is not necessary if the circuit does not contain a bonded ground source. Electrical troubleshooting will be required to find the problem so it may be corrected to prevent the tripping circuit breaker. The problem may be where a portion of an uninsulated wire is coming into contact with the another wire of the circuit and causing a direct short, however this type of problem can be corrected by repositioning the wires and gently folding the wires into the back portion of the outlet box before installing the outlet.
As the electrician has mentioned, it would be good to upgrade the home electrical wiring when possible.
I hope this helps,
Dave

Hi George,
What you are explaining is accurate and normal for a GFCI outlet that does not have a ground wire. In this situation, one way to test the GFCI is to use an induction type voltage tester. Plug an extension cord into an outlet that does have a ground, bring the end of the extension cord to the GFCI outlet to be tested, and then connect one lead wire of the induction voltage tester into the ground of the extension cord, and the other lead wire of the tester into the small blade power prong of the GFCI outlet and this will trip the GFCI outlet. If the GFCI outlet is located in a bathroom or kitchen and the water facet is nearby, then use the same procedure as explained above, except use any grounded metal part of the facet as the ground source. The same test may be accomplished using a grounded drain pipe. Be aware that testing to a facet or drain pipe will not work if the home plumbing is plastic or a non-metalic material that does not have a connection to earth ground. The key for the normal operation and testing of a GFCI is that a ground source must be present.
I hope this helps,
Dave

Sonia,
If there is no ground wire available then nothing connects to the ground terminal on the GFI outlet.
The Black wire of the 120 volt circuit attaches to the Brass screw terminal, designated LINE.
The White Neutral wire of the 120 volt circuit attaches to the Silver screw terminal, designated LINE.
If the GFI outlet will not have a ground wire then the label which states this must be attached.
Electrical Codes may apply for specific areas.

Hi Ray,
Using a GFCI will not create a ground, so I would not recommend this. A typical air conditioner unit does not require GFCI protection, however it does require an equipment ground so I would investigate the circuit further to see if a ground wire is available, and if not then one should be added.
Alternatively, a new circuit may be installed which provides the necessary ground wire.
