branch panel grounding question
I'll be running THHN through EMT to the branch panel, and I was wondering if
I could run a bare copper grounding conductor outside of the conduit? I have a solid ground wire on hand (free), but I'd rather not pull it through the conduit. Thanks, Bill |

If the conduit is metal, the conduit itself is permitted to be the grounding conductor. Not around here (Saskatchewan, Canada). We need to have a separate grounding conductor. The conduit must be grounded, but it can't actually be the conductor. Chris |

I suspect that's no longer true, because we just got a barn with metal conduit rewired with a real ground wire after 10 years, at the inspector's expense. Nick |

No. Code says all conductors for any given circuit must be *in* the same cable, raceway, conduit, etc. I have a solid ground wire on hand (free), but I'd rather not pull it through the conduit. If the conduit is metal, the conduit itself is permitted to be the grounding conductor. -- Regards, Doug Miller (alphageek at milmac dot com) It's time to throw all their damned tea in the harbor again. |

Thanks, Bill IMHO, since not your electrician: Some might suggest you omit the equipment grounding conductor, since you are using emt, but I find it safer to include it. Just make sure your ground wire is sized properly, per codes. Also, check with your local codes, even though you don't have to route a ground wire, since emt, your local codes might have more restrictive rules. later, tom @ www. |

What inspector is required to 'fix' things? This confused me too at first, but I think he means that the inspector failed to tell the buyer that there was something wrong, that the inspector had a duty to notice. And the buyer bought. So the inspector, maybe via his insurance, had to pay for the repair. later, tom @ www.FreeCreditCheckGuide.com |
