Running a separate wire for grounding
Although I do not understand the reasoning for this code rule, I always
understood that if you have the old 2 prong outlets, fed from old cable, which does not have a ground wire, that you can NOT run a single green wire from the breaker box ground buss, to the ourlet(s), to ground them. Yet, I saw someone suggest doing this on a blog. Of course blogs are like this newsgroup, and are not always good information. As I said, I think this rule is sort of senseless, because as long as the added wire was of the same gauge, connected to the ground buss in the panel, it would make safer wiring. Of course replacing the old cable is the preferred method, that is not always possible without ripping a house apart. Just wondering if anyone has any further information about doing this? Is this ever allowed for any reasons? |

If the old wiring is in conduit(metal), I
have seen the conduit itself used as the ground for the new three-holers. I'm not sure what code has to say about that. |

As far as I know, and this is as of 2013, when I asked a similar question, a separate ground was allowed to be run to a junction box to supply a ground that didn't exist, as opposed to running a new length of grounded Romex. Please cite the section of code that doesn't allow it. |

However for the work involved to install the separate ground wire you might as well install a new cable with the ground wire in it. John Grabowski http://www.MrElectrician.TV |

That would depend on how you run that additional ground wire. As long as it's compliant with code, eg not a 20 gauge wire run around the whole house, it's OK. Yet, I saw someone suggest doing this on a blog. Of course blogs are like this newsgroup, and are not always good information. As I said, I think this rule is sort of senseless, There is no such rule. because as long as the added wire was of the same gauge, connected to the ground buss in the panel, it would make safer wiring.
