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

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.
