300.20 is still in the code, I don't believe it applies to grounding electrode conductors. Although, the application or theory may be the same. The connector is called a kenny clamp, new to the market for approximately 1.5 years. Its listed for bonding and grounding under UL/Ansi 467 standard...
Thanks for your response. The inspector claims NFPA recommends bonding grounding electrodes due to side flash due to a lightning strike and 250.8 NEC for applying a listed fitting for grounding. Also 110.3(B), 300.15 NEC listed for the purpose and when a conductor enters a box a listed fitting...
The inspector quotes NFPA 780 and applicable NEC articles. Compliance with his request is not an issue, but bonding at the enclosure has never been a NEC code requirement. Although, I believe there's supporting Code for his argument. The inspector is also concerned with the choke effect under...
Is it necessary to bond the grounding electrode conductor when it enters metallic enclosures at the sevice equipment and separately derived systems. My design did not call for a connector at the point of entrance to the metallic enclosure and the Electrical Inspector is requiring that I use the...
