Hey all. This is my first post so I hope all goes well. I have moved to CO from MI where I hold a journeymans license. I am a power plant electrician here and don't do any residential but my qustions deal with residential.

I see from some of the photos posted that the GEC used is solid copper. In MI, the standard GEC is #6 stranded bare copper with two 5/8" x 10' grounds driven not less than 6' apart. If a water meter is present, you must also bond around the water meter. Same rules in CO? If the solid GEC is required, what's up with that? I have only run across solid copper in my remodels.

Second question, my wifes clients (she is a realtor) just had a home inspector tell them that a GFCI was required on every circuit. I have neverr herd of this and to my knowledge, the NEC doesn't require this. Any feedback?

Thanks - Michiganboy

The largest required for ground rods is #6, but for a GEC to a water line or building steel, you need to size in accordance with Table 250.66

Sounds like something got lost in the translation. Nobody would say such a thing. UNLESS... this home has all ungrounded wiring and somebody refitted all the recs with 3 prong recs.

Thanks for the response. I am tasking my wife with gathering more info. I'll post that information when it becomes availlable.

It looks like the 2008 NEC will require AFCI's on pretty much all the 120V circuits. We'll have to wait and see how that hashes out by the time the books hit the press. I've got a copy of the 2008 NEC ROC that I've just now started to browse. I should be able to find some neat conversation starters in the coming weeks from that document.
