You are interpreting the code correctly. Here's a breakdown: General Rule

Grounding electrode conductors (GECs) should be a

continuous length without splices or joints. Exceptions

There are some exceptions to the general rule that allow for splicing under specific circumstances, (as listed in 250.30(A)(5) and (A)(6), 250.30(B)(1), and 250.68(C).)

Permitted Splicing Methods

When splicing is permitted (either because of an exception or because the AHJ allows it in specific situations), the only acceptable methods are: Irreversible compression-type connectors

listed as grounding and bonding equipment Exothermic welding.

In your situation

You can only splice with an irreversible crimp connector

if and only if one of the following applies:1. One of the Exceptions in 250.30(A)(5) and (A)(6), 250.30(B)(1), and 250.68(C). applies. Important Considerations



Listed Connectors

The irreversible compression connector must be

listed for grounding and bonding purposes. This means it has been tested and certified for this specific application. Authority Having Jurisdiction (AHJ)

Always consult with your local electrical inspector (AHJ). They have the final say in interpreting and enforcing the code. They might have local amendments or interpretations that affect your situation.

In summary, splicing a grounding electrode conductor is generally not allowed unless an exception applies. If splicing is permitted (due to an exception or AHJ approval), you must use an irreversible compression connector listed for grounding and bonding or exothermic welding. Flag for review
