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.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Electrical Grounding and Bonding Systems
  • Substation and Utility Grounding Connections
  • Cable-to-Cable Splicing for Ground Conductors
  • Industrial and Commercial Electrical Installations
  • Telecommunications and Data Center Grounding

Why nVent CADDY?

nVent CADDY carries forward the legacy of the Erico Cadweld® product line, a name long trusted by electrical professionals for permanent, weld-based grounding and bonding connections. The TAC2G2G mold is built to deliver a consistent, repeatable cable-to-cable tee connection for installers who need a splice that performs for the life of the installation, without the ongoing maintenance concerns that come with mechanical connectors.

nVent CADDY TAC2G2G – Frequently Asked Questions

1) What cable size does the nVent CADDY TAC2G2G mold fit?
The TAC2G2G is sized for 2/0 AWG concentric cable on both the run and the branch. It is a single-size mold, so it will not accept 1/0 or 4/0 conductors, and it is not intended for compact or stranded constructions outside the concentric class it was cut for. If your run is 2/0 concentric and your tap is 2/0 concentric, this is the matching mold.
2) Is the TAC2G2G a tee mold or a straight splice mold?
Horizontal tee. The TAC2G2G lets a branch conductor tap into a continuous horizontal run of 2/0 cable. If you need to join two cable ends end-to-end, or make a cross or a vertical connection, that is a different mold configuration, not this one.
3) Does the TAC2G2G mold come with the weld metal and everything needed to make the connection?
The TAC2G2G is the graphite mold only. Cadweld exothermic connections also require the welding material (shot) specified by nVent CADDY for this connection type, plus the ignition source and handle clamp. Order the matching weld material with the mold, otherwise you have the form but nothing to pour into it.
4) Is the TAC2G2G the same as the old Erico Cadweld tee mold?
Same product line. The Cadweld range was formerly produced under the Erico brand and is now sold under nVent CADDY, and the TAC2G2G designation carries over. If your spec or old purchase record calls out an Erico TAC2G2G, this is the part.
5) Why use a Cadweld exothermic tee instead of a bolted or compression grounding connector?
An exothermic weld fuses the two conductors into one continuous metallic path, so there is nothing to re-torque, back off, or build resistance at the interface. Bolted lugs and set-screw connectors are faster to install and are removable, which matters for testable or temporary connections, but they need periodic inspection. For buried, encased, or inaccessible grounding splices, the welded tee is the usual choice because it is maintenance-free once poured.
6) Can I reuse a Cadweld TAC2G2G mold for more than one connection?
Yes. Graphite Cadweld molds like the TAC2G2G are designed for repeated connections of the same configuration and cable size, which is why crews buy one mold per connection type and stock weld material by the box. The mold wears with each pour, so plan on replacing it when the cavity and cable seats no longer seal cleanly against the conductor.
7) What jobs is the 2/0 Cadweld tee mold typically specified for?
Substation and utility ground grids, industrial and commercial ground networks, and telecom and data center grounding, anywhere a branch ground conductor has to tap a continuous 2/0 run. It is a grounding and bonding part, not a power-conductor splice.
8) Where do I find the full nVent CADDY spec data for the TAC2G2G?
The complete nVent CADDY catalog covering the Cadweld mold range, including the matching weld material callouts for cable-to-cable tee connections, is published by the manufacturer as a full catalog PDF and is carried with the product record.
