Test them to identify the neutral wire and the hot wire. Use tape to mark them. This will keep you from confusing the two. Connect the two wires coming out of the outlet box to the line side of your GFCI receptacle. Once all the screws have been tightened, you can re-energize the circuit. Use an analog tester to determine whether or not the GFCI outlet has power. You can check out this video that has a detailed breakdown of this process.
It includes pictures. Hire a professional before you electrocute yourself. Perhaps, it does not create a path to the ground. It will also work just like a grounded GFCI. It will respond to ground faults by de-energizing the circuit.
Thus, a GFCI without ground is safer than an ordinary outlet without ground. Ungrounded outlets are dangerous. They are vulnerable to surges, sparks, and arcing that may start a fire by igniting the flammable objects in the vicinity, including the furniture. Kolb Electric associates ungrounded outlets with property loss and dangerous shocks. Attach a sticker that tells everyone who sees the GFCI that it is not grounded.
If the GFCI is properly labeled, an inspector will not complain. You normally find ungrounded GFCIs in older homes that do not have ground wiring. Many people are unwilling to replace the wiring in older homes to accommodate grounded GFCIs. The GFCI will respond once that imbalance exceeds a specific threshold. It will interrupt the flow of current, preventing the outlet from shocking the consumer or destroying their equipment. We can accomplish this by turning off the power at the breaker box.
Working on outlets that have the power on is not safe. Use a voltmeter to check the outlet before proceeding further in the operation. Unscrew the old outlet and detach all the wires in the receptacle. Separate the hot wires, which are black, from the neutral wire white. The terminals are usually labeled on the back of the receptacles. LOAD terminals are typically covered with tape.
Locate the black wire hot from the old outlet. The manufacturers often provide a label along with the outlet for this specific circumstance.
This will warn people of the unreliability of the outlet from the power surge. You now have a GFCI outlet connected with no ground wire. It surely works like an upgraded electrical outlet!
However, if you end up having four sets of wires, identifying the hot can be tough. Disconnect the outlet and separate the wires. After separating the wires, turn the power back on again.
As the electrician has mentioned, it would be good to upgrade the home electrical wiring when possible. I just moved to a new home that requires an occupancy permit. In order to pass the inspector had stated that all GFCI outlets must be grounded. Running to the outlets is either a or without a ground. Is it legal to ground these to the the box. If not what are my options. Thanks, Sam. 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.
