Need more information.
Was this an equipment grounding conductor?

Re: splicing
If this is the grounding electrode conductor and you can see his/her crimp is well made, I would have no problem with this connection - which is permitted by the NEC.

Re: splicing
kjones,
Perhaps you would be interested in sharing your thoughts and reasons for questioning this?
Just curious,
Bob

Re: splicing
See section 25o.64(C) has the requirements for the GEC and how it can be spliced.

Re: splicing
attended a 4-hour continuous education class the other night.....gec must be attached to electrodes by means of: weld, crimp, or irreversable clamp. attachment must be permanent! what type of connection do you prefer? have used cadwell before....not sure about crimp method....used clamps that have a bolt to tighten (torque) but are removeable...we must drive 2- rods in our area for residential...what are your thoughts on proper attachment of gec to ge?

Re: splicing
The information that you received at the grounding class is not correct. There is no requirement that the connection between the grounding electrode and the grounding electrode conductor be irreversible. That requirement only applies to splices in the GEC.

Re: splicing
For prescriptive grounding the connection type does not matter. Keep in mind the purpose of the ground rod is for lighting, the connection is not all that critical. An acorn clamp is fine.
For performance grounding then you design the connection for the intended purpose. I install radio antenna for control systems, a long term rugged installation is required, so I use 2 AWG and cad weld.

Re: splicing
thanks Don and Tom for your responses. 4 hour class given by inspector that works in a different jurisdiction than I do! "He" wants the connection from ge to gec to be welded, crimped or irreversable clamp....inspector in jurisdiction where I work says an acorn clamp is sufficient! Once again the AHJ has authority and you must remember the NEC is for minimum requirements! I try to work under one jurisdiction so differences of opinion like this will not disrupt the work flow and bring hardship between myself and the AHJ! I know many of you must work in several jurisdictions and to that I say have lots of patience! You and the AHJ must get along...even when you dissagree!

Re: splicing
I disagree with your statement. You are correct that the AHJ is the person responsible for interpreting the rules. An interpretation, however, is not an option for this. 250.70 spells it out quite clearly...there is no interpretation to be made. As Don said, your inspector is wrong.
An interpretation would be something like defining the term "subject to physical damage" or "likely to become energized". Again, 90.4 does not create an all powerful being, it creates the inspection department.

I have to agree with Ryan as this is a simple case of the instructor mixing up 250.64(C) with 250.70 even the wording is from 250.64(C)
By the way ask this instructor how you crimp to a GE?
