Depending on local codes (stress dependent) an upgrade may be necessary.
Pure NEC enforcement (Based on NJ UCC laws) I (AHJ) cannot mandate replacement. However, those that are replaced must comply with the adopted NEC, as amended with the NJ UCC Electrical Subcode. There are still non-ground receptacles on many shelves.
Consult with an area lic. electrical contractor for your local requirements.
Thanks for replying. I did not change a few 2 prongs outlet to Leviton GFCIs without grounding wiring connected as there are none ground wires in the boxes.
Wiring is correct: Hot-black and neutral-white on the "Line" end.
But GFCI outlets cannot be "TESTed" or "RESET" with the two buttons on the GFCI outlets. The GFCI outlets are providing electricity and and green light indicators are on. A handheld wiring tester shows that the outlets are "Open Ground" (as there are not ground wires in the boxes) and cannot be reset as well.
Thanks Greg! Leviton told me the same, that its GFCI does not have to use the grounding wire. I do not know why it does not trip as the wiring is simple. An electrician told me that because there is not enough current draining out the circurt when "TESTing" without grounding conductor, it may not trip when pusting the TEST button or using a GFCI handheld tester, but it will provide protection needed in a situation of Ground Fault. Please advise. Thanks, Hal

An electrician explained that because there is not enough current draining out the circurt without grounding conductor when "TESTing" to trip or interrupt when pushing the TEST button or using a GFCI handheld tester, it will provide protection needed in a situation of Ground Fault. Please advise. Thanks so much, Hal
The GFCI works by comparing the current it the white to the current in the black. If more is going out than comes back in they assume a ground fault. The test is just a resistor in the device that causes an artificial imbalance in that transformer, using the line and neutral. The ground is not involved.
