can the copper bonding jumper be separate between the rods, as shown in the photos or does it need to be continual be rod 1 and rod 2.
I teach that it and be run from meter to rod stop rod to rod, which has caused many heated arguments at classes I am teaching at.
I teach safety classes for NAARSO which is a group of amusement ride safety and training people. At schools, I have had a ton of push back because of the word "continual". Please tell me if I an ok to teach it as separate or should I be saying one length of copper "uncut" at the # 1 rod?
Thanks for your help.

Most inspectors in this area feel the connection to the 1stb rod must be continuous {or meet 250.64(C)} but the connection to the 2nd rod is a jumper and can be a separate conductor. At the 1st rod, 2 acron clamps are required locally as they feel the clamp is listed for one wire.

I agree with Augie, all electrodes after the first can be connected with individual jumpers. As he points out, the clamp can be a reason to use a continuous conductor so it can pass through and you would only need one.

The conductor to the first rod is the GEC and must be continuos or if spliced it must be irreversible spliced (typically crimped or Cadwelded). the conductor to the second rod is a bonding jumper and that can be connected by using two acorn clamps.
