UL 467 irreversible compression C-tap grounding connector for a 3/0 AWG–500 MCM run with a 3/0 AWG–500 MCM tap — the largest equal-range C-tap in the line, for full-size junctions on heavy grid conductor. The open C-body hooks over an uncut run. Listed for direct burial and concrete encasement. Covers the range Burndy HYGROUND HYTAP™ splits across three catalog numbers — same 12-ton tool platform.

One CT connector spans the range Burndy splits across three catalog numbers. Cross-references identify equivalent function and conductor range; verify die selection against the index stamped on the connector.
Where it's used
- 500 MCM grid-to-grid tees on substation, transmission, and generation grounding mats
- Buried junctions with no access box (NEC 250.68(A) Exception)
- Maximum-fault-current paths specifying IEEE 837-class permanent connections
How to install
Wire-brush both conductors to bright metal, hook the C over the uncut run, lay the tap in the saddle with tail past the connector ends, 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.
