Cross-reference
| Manufacturer | Part No. | Covers | Die index |
|---|---|---|---|
| Burndy HYGROUND | YGHP29C29 | 1/0–250 kcmil run or 1/2"–5/8" rod; 3/0–250 kcmil tap | 997 (U997), 1 crimp |
Cross-references identify equivalent function and conductor/rod range; verify die selection against the index stamped on the connector.
Where it's used
- Heavy-conductor (3/0–250 MCM) rod terminations on industrial and substation grids
- Buried and concrete-encased connections — no access box required (NEC 250.68(A) Exception)
- Sites specifying IEEE 837-class permanent connections on mixed 1/2"–5/8" rod stock
How to install
Drive the rod, wire-brush rod and conductor to bright metal, seat the connector with conductor tail visible past the barrel, and crimp with the stamped die index until the dies fully bottom — center first, working outward.

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.
