Re-Bar Ground Rod

[John Evans]

For the second time in one week, I found standard re-bar placed for the main panel ground. Of course, the rods were very rusted, which I believe causes a potential bonding issue. To the best of my knowledge, all ground rods must a non-corrosive material, such as copper. In both cases. the rods were set in a concrete slab, one in a garage and the other in a basement. Looking for opinions, as I did call these out for correction.

Hmmm...are you sure they are not UFER connections?..kinda looks like 4 AWG Solid going to it.......while I dont like the ACORN at the connections...many have no problem with it...so since we see a Concrete Floor, Re-bar and 4 AWG......could it not be a UFER connection....

generally...but seen used all the time.....you know the ole saying...." Clamp does not define the connection...if clamped by someone not knowing what a proper clamp is "

[Paul W. Abernathy]

Either way.......sticking out like it is would indeed be dangerous...lord knows kids playing around it could be impaled....heck adults even...

You found a: Concrete-Encased Electrode............

consisting of at least 6.0 m (20 ft) of one or more bare or zinc galvanized or other electrically conductive
coated steel reinforcing bars or rods of not less than 13 mm (1⁄2 in.) in diameter, ....... this is an acceptable method.

lol....better late than never JOE...LOL....Glad to see ya

As stated in my first post....it is a CEE...but it appears many are still not sure what they are. I did a seminar yesterday and asked the guys...do they know what a UFER is and only (2) electricians in the class said they did.....I found that shocking actually.....

[Paul W. Abernathy]

Do you find the same joe at your seminars....you speak about CEE or "UFER" and the majority act like they have no clue what it is......very strange as I have known about them since I started in the field....

Paul:

Same here!

The "one or more" part was made clear to clarify up one of Mike's Proposals for the 1981/84 revision, when he sent in 125 proposals. This one asked to make it clear that the rebar had to be in one continuous length, and CMP-5 said they never expected them to be a full 20 ft. the 4 AWG is required to be the full 20 feet as so stated.

UFER was his name and was well known ....... PS: Expert needed to add information here ........

[Paul W. Abernathy]

no additional info needed...lol.......We have SPOKEN !

True, it probably depends on where they went to school, some in vocational where the teacher was an electrician, or others in the field, and some with no training at all.

The subject of the UFER is covered in many IAEI articles now and as far back as the 50's, I have the original magazine articles written by Herbert Ufer and Eustace Soares.

loll...I hear ya....sad thing is these seminars are CE Required ones and I would expect them to know what a UFER is.....but alas when they leave my class they know what one is...and how to install it properly...lol
