Just one electrode necessary, right?

as the code states in 250.50 only one grounding electrode is necessary if none else exists. many electricians are greatly surprised when i tell them only one is required.
many will not even believe it after reading the code section. one electrician even went so far as to say that "if the supply house has a ground rod in stock then it exists and must be installed". some places around the country won't allow a ufer or concrete encased electrode; usually framers turned inspectors.
i'm a great fan of concrete encased (rocky mountains). thank you
 
One, if its a rod, pipe or plate, might lead to two per 250.56
 
Yup, if there are none you're required to make one. Seems like most modern buildings would require a CEE.

Me too, I love a ufer,,,,no ground rods!! Oddly enough, it still confuses some inspectors. I got a call last month from an inspector saying I didn't have any ground rods.:cool:

Yup for some single family dwellings you're still looking at no rebar in the footings. Maybe I should have said many instead of most.
