Cross-references identify equivalent function and conductor/rod range; verify die selection against the index stamped on the connector.

Where it's used

  • Two equipment bonds landed at a single grid point — one crimp instead of two connectors
  • Buried and concrete-encased grid taps — no access box required (NEC 250.68(A) Exception)
  • Substation and data-center grids running 250–500 MCM conductor

How to install

Wire-brush all conductors to bright metal, slide the run through the run bore, insert the tap conductor(s) fully so they show past the barrel, and crimp with the stamped die index until the dies fully bottom — center first, working outward. Full field procedure: How to Crimp Irreversible Compression Grounding Connectors.

Why irreversible compression

NEC 250.64(C)(1) permits grounding electrode conductor splices only by irreversible compression or exothermic welding. Compression installs in wet trenches with no hot-work permit, and every crimp embosses its die index for inspection. More: Where, How, and Why to Use Irreversible Compression Grounding.
