The Figure 8 compression ground rod connector joins 5/8 inch ground rods to 4-250 MCM copper conductors. The dual-cavity design permits two continuous parallel conductors in a compact form factor suited for direct burial applications. Pre-filled with anti-oxidant compound, the connector eliminates field preparation and reduces installation time. Electricians use this connector in grounding electrode systems, lightning protection networks, and utility substations where space constraints and environmental exposure demand reliable, code-compliant terminations.

FAQ

Can I use this connector for two separate conductors or only continuous parallel runs?

The Figure 8 design accepts two continuous parallel conductors. Do not use for splicing two independent conductors; select a butt splice or tap connector for those applications.

Is additional anti-oxidant required for direct burial?

No. The connector arrives pre-filled with anti-oxidant compound. No field application needed.

Does UL96 listing satisfy NEC lightning protection requirements?

Yes. UL96 listing covers lightning protection system components per NFPA 780. Verify with your AHJ that the installation meets local amendments.
