This post mentions that it is now legal to add a separate wire to ground an outlet. What is the proper way to do this? Does the wire need to follow the same path as the ungrounded 2 wire path? How would the ground enter the junction box? How is it secured?
Is it legal to install 3 prong outlet without ground in the State of Georgia?
Best Answer
From the 2017 National Electrical Code:
No, it isn't required but if it did that would be preferable.
It could be fished into another opening with a cable clamp.
To the grounding-type-receptacle's ground lug and to the box, if it is metal, by means of a 10-32 ground screw.
There are many ways to accomplish this. These are the preferred methods of the trade but there are other acceptable ways.
Good luck!
