Cross-Reference

Equivalent to irreversible compression grounding connectors from major manufacturers. Provides permanent parallel conductor splice for grounding electrode conductors and lightning protection systems at lower cost than comparable branded alternatives.

FAQ

What tool is required for installation?

Requires industry-standard compression tooling with appropriate die set for the conductor size. Connector is irreversible once compressed; verify conductor fit before crimping.

Is this suitable for exothermic welding alternatives?

Yes. UL 467 and UL96 listing permits use as permanent grounding and lightning protection connection where code requires irreversible compression or exothermic welded joints.

Can this be used for phase conductors?

While rated 600V, this connector is specifically designed and listed for grounding and lightning protection applications. Verify local code requirements for phase conductor splicing.
