Overview
The nVent Erico GRT161G is a Cadweld exothermic graphite mold engineered to connect #6 solid AWG copper conductor to a 5/8 in. copper-bonded ground rod. Cadweld exothermic connections form a permanent molecular bond with current-carrying capacity equal to the conductor itself — making them the preferred choice for grounding systems where long-term reliability and low resistance are critical. No external power source is required, and installers can be trained quickly for field use. Connections are visually inspectable for quality assurance.
Key Features
- Forms a permanent, low-resistance exothermic connection via molecular bond
- Current-carrying capacity rated equal to the connected conductor
- Portable installation — no external power source required
- Fast installer training for consistent field results
- Visually inspectable connections for quality verification
- Includes mini EZ handle clamp attached to mold
- Compatible with smokeless Cadweld Exolon molds for low-ventilation areas (add XL prefix to part number)
- Welding material (32 or 32PLUSF20) sold separately
