nVent CADDY TAC2G2G Cable-to-Cable Horizontal Tee Mold Connector for 2/0 AWG Concentric Cadweld® Connections

nVent CADDY TAC2G2G Cable-to-Cable Horizontal Tee Mold Connector for 2/0 AWG Concentric Cadweld® Connections

The nVent CADDY TAC2G2G is a cable-to-cable horizontal tee mold connector engineered for the Cadweld® exothermic welding process, permanently joining 2/0 AWG concentric cables into a single, continuous, low-resistance connection. Formerly produced under the Erico brand, this mold forms a molecular weld between conductors rather than a mechanical clamp, so the finished connection will not loosen, back off, or lose contact area over the service life of the installation. The TAC2G2G forms a horizontal tee splice, letting a branch conductor tap into a continuous run of 2/0 AWG concentric cable, a configuration commonly needed throughout grounding and bonding networks.

Key Features

• Cable-to-Cable Connection: Joins two runs of 2/0 AWG concentric cable in a horizontal tee configuration for branch grounding and bonding connections.
• Cadweld® Exothermic Weld Process: Uses the Cadweld® molecular welding method to fuse conductors into one continuous, permanent electrical path rather than a bolted or clamped joint.
• Wire Size: Sized specifically for 2/0 AWG concentric cable, matching common grounding and bonding conductor sizing.
• Horizontal Tee Configuration: Model TAC2G2G is a tee-style mold, allowing a branch cable to splice into a horizontal run without additional mechanical hardware.
• Permanent, Maintenance-Free Joint: Because the connection is welded rather than mechanically fastened, there are no bolts, set-screws, or lugs to re-torque, loosen, or corrode over time.
• Cadweld® System Component: Designed to work as part of the Cadweld® exothermic welding system alongside the corresponding welding materials specified by nVent CADDY for this connection type.
