ECN Forum Forums General Topics of the Trade General Discussion Area 1/2" nonferrous ground rods

Does anyone know if galvanized ground rods come under the definition of nonferrous ground rod? If so, then does that not fall under the exception of using 1/2" ground rods. Just wondering. Our Lowes here only carries 1/2" galvanized ground rods. I picked up two for a job, because I didn't want to go across town to the supply house. Took a chance on driving them, and was turned down. Inspector said they had to be 5/8", which I always have driven, but I looked at the code, and seen where stainless steel or nonferrous ground rods could be 1/2". Nonferrous must have a broader meaning than I thought. Any thoughts on the matter is aprreciated. Thanks. By the way, it's been a while since I have been able to be on the forum. I had to get a permanent job, which didn't work out, but I'm back on my own again... Work seems to be picking up some again.... Thanks... Steve.

Is this another case where EVERYONE is convinced the supplier, in this case a ' big box ' supply house, only carries the proper item to meet the NEC ?

Just this week, had an AHJ tell me that [ a well known electrical suppier ] doesn't carry any items which are not listed, such as per NEC 352.10(G).

The galvanizing on the surface of an iron or steel rod does not make it a nonferrous rod. Does your magnet stick to the rod? If so it must be at least 5/8".
