nVent CADDY HDC34 Silicon Bronze Ground Rod Clamp, 3/4-Inch

The nVent CADDY HDC34 Silicon Bronze Ground Rod Clamp delivers a secure, corrosion-resistant connection for grounding electrical systems. Sized to fit 3/4-Inch ground rods, this clamp accepts a wide conductor range from 8-AWG solid to 1/0-AWG stranded wire, giving electricians flexibility when terminating grounding electrode conductors and bonding jumpers on the same clamp body. Formerly known under the Erico name and now manufactured under the nVent CADDY brand, the HDC34 features a silicon bronze body engineered to resist corrosion in demanding outdoor, underground, and wet-location grounding installations where long-term connection integrity is essential. Its clamp-style design allows a single fitting to accept a broad span of conductor sizes, simplifying stock and installation for electrical contractors.

Key Features

  • Trade Size: Sized to fit 3/4-Inch ground rods for a secure, properly seated clamp connection at the grounding electrode.
  • Durable Silicon Bronze Construction: The silicon bronze body resists corrosion, helping maintain a reliable, low-resistance ground path in outdoor, underground, and wet-location installations over the long term.
  • Wide Conductor Range: Accepts conductors from 8-AWG solid up to 1/0-AWG stranded, accommodating a broad range of grounding electrode and bonding conductor sizes on a single clamp body.
  • Ground Rod Clamp Design: Provides a dependable mechanical and electrical connection between the grounding conductor and the ground rod electrode.
  • Single-Clamp Versatility: One clamp body accommodates both solid and stranded conductors across the rated range, reducing the number of SKUs an electrical contractor needs to stock.
  • Field-Proven Design: Continues the trusted Erico HDC-series clamp design, now manufactured and supported under the nVent CADDY brand.

nVent CADDY HDC34 – Frequently Asked Questions

1) What size grounding conductor can I terminate in an HDC34 ground rod clamp?
The HDC34 takes conductors from 8-AWG solid up to 1/0-AWG stranded, so the same clamp body covers a #6 grounding electrode conductor on a typical residential or light commercial service as well as heavier bonding jumpers up to 1/0. Both solid and stranded wire are accepted across that range.
2) Can a bronze ground rod clamp be buried or left in a wet location?
The HDC34 uses a silicon bronze body chosen for corrosion resistance in outdoor, underground, and wet-location grounding work, where a plated steel clamp would eventually corrode and drive up resistance in the ground path. That is why it is the usual choice for a direct-buried rod connection at a ground rod or ufer tie-in.
3) Do I need a different ground rod clamp for a mix of solid and stranded wire on the same job?
No. One HDC34 handles both solid and stranded conductors anywhere in the 8-AWG to 1/0-AWG range, so a contractor or MRO stockroom can carry a single clamp for 3/4-inch rods instead of separate parts per conductor type. That is the main reason it shows up on standardized grounding kits.
4) Is the HDC34 right for a renovation where I am reconnecting to an existing driven rod?
It works for that as long as the existing electrode is a 3/4-inch rod, which the HDC34 is sized for, and the conductor you are reterminating falls between 8-AWG solid and 1/0-AWG stranded. It is used on both new construction and renovation grounding work, including commercial and industrial services.
