@Farmall-Joe posted:Well we've all been respectful with our concerns and laid out the reasons why. There is no joke and no one is coping out. It is not our place to research the entire code book for you. For anyone else who would like to heed the warning here is the primary code being probably violated...i say probably because i have not researched the entire electric code here. It is up to the homeowner to abide by the laws and provide safety for his or her family, future home owners or anyone potentially working in the house. I reiterate that RichieC's licensed electrician felt he should rewire to be in compliance with the code.
3701.2 Allowable wiring methods.The allowable wiring methods for electrical installations shall be those listed in Table E3701.2. Single conductors shall be used only where part of one of the recognized wiring methods listed in Table E3701.2.TABLE E3701.2 ALLOWABLE WIRING METHODS

E3701.3 Circuit conductors.
All conductors of a circuit, including equipment grounding conductors, shall be contained in the same raceway, trench, cable or cord.
And for the record, i've been an electrical engineer in the nuclear power industry for 20 years...not an "amateur".
You can lead a horse to water...
That requirement is for new construction wiring, not for retro-fitting a ground wire to a two wire system.
Here is the 2017 Code requirement and comment;
From the 2017 National Electrical Code:
(C) Nongrounding Receptacle Replacement or Branch Circuit Extensions. The equipment grounding conductor of a grounding-type receptacle or a branch-circuit extension shall be permitted to be connected to any of the following: (1) Any accessible point on the grounding electrode system as described in 250.50 (2) Any accessible point on the grounding electrode conductor (3) The equipment grounding terminal bar within the enclosure where the branch circuit for the receptacle or branch circuit originates (4) An equipment grounding conductor that is part of another branch circuit that originates from the enclosure where the branch circuit for the receptacle or branch circuit originates (5) For grounded systems, the grounded service conductor within the service equipment enclosure (6) For ungrounded systems, the grounding terminal bar within the service equipment enclosure
Does the wire need to follow the same path as the ungrounded 2 wire path?
No, it isn't required but if it did that would be preferable.
How would the ground enter the junction box?
It could be fished into another opening with a cable clamp.
How is it secured?
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.
