Question:

Good Day,

Our question is about bonding jumpers between grounding electrodes of a grounding electrode system. Can they be spliced or do they need to be in a continuous length?

Your opinion matters.

Thanks,

Mark Wilson

Answer:

Hi Mark,

Thanks for the question. Grounding electrode conductors are generally required to be installed without a splice or joint other than those permitted by 250.64(C)(1) through (4). Bonding jumpers used to connect grounding electrodes of a grounding electrode system together are not required to be run in a continuous (unbroken) fashion. They can be splice and usually are as they terminated to each electrode used in the grounding electrode system. Check out Sections 250.64(C) and 250.53(C) which indicates the bonding jumper(s) used to connect the grounding electrodes together to form the grounding electrode system shall be installed in accordance with 250.64(A), (B), and (E), shall be sized in accordance with 250.66, and shall be connected in the manner specified in 250.70. The continuous requirement does not apply to these bonding jumpers.
