nVent CADDY GT1181GPLUS CADWELD Exothermic Welding Connector

The nVent CADDY GT1181GPLUS is a CADWELD exothermic welding connector from the nVent ERICO CADWELD line, engineered to create a permanent, molecular-bond electrical connection for grounding and bonding work. Unlike mechanical lugs or clamps, the CADWELD exothermic welding process fuses the conductors together into one continuous, homogeneous conductor at the connection point, rather than relying on surface contact and applied torque. This eliminates the loosening, resistance increase, and corrosion that mechanical connections can develop over years of service. The specific configuration for this connection is identified by the model designation GT1181GPLUS within the broader CADWELD system, and it is intended for use by qualified electricians and contractors completing grounding and bonding connections on electrical systems.

Key Features

  • Exothermic Welding Process: Uses the CADWELD molecular-bond welding method to permanently fuse conductors at the point of connection, rather than clamping or bolting them together.
  • Model Designation: Identified as GT1181GPLUS within the nVent ERICO CADWELD product line, distinguishing this specific connection configuration from other CADWELD offerings.
  • Permanent, Low-Resistance Connection: Creates a fused joint intended to maintain consistent conductivity without loosening or increasing in resistance the way mechanical connectors can over time.
  • Corrosion Resistance at the Joint: Because the conductors are fused into a single continuous connection, there is no dissimilar-metal interface at the joint to promote galvanic corrosion the way a clamped connection can.
  • Grounding & Bonding Application: Purpose-built for electrical grounding and bonding connections rather than general-purpose wiring splices.
  • nVent CADDY Brand: Backed by nVent, a recognized manufacturer of electrical connection, grounding, and support products used across commercial and industrial installations.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications, including conductor sizes and weld metal quantity for the GT1181GPLUS configuration.

Typical Applications

  • Electrical Grounding and Bonding Connections
  • Commercial and Industrial Electrical Installations
  • Utility, Substation, and Data Center Grounding Systems
  • Permanent Conductor-to-Conductor or Conductor-to-Ground Connections
  • Applications Requiring a Connection That Will Not Loosen or Corrode Over Time

Why nVent CADDY?

nVent CADDY offers the CADWELD exothermic welding system as a proven method for creating permanent electrical connections that are designed to hold up under demanding grounding and bonding conditions. Because the CADWELD process fuses conductors into a single continuous connection rather than relying on mechanical contact, it is intended to deliver a long-lasting, low-maintenance connection point. Choosing a CADWELD connector from nVent CADDY gives electrical professionals a well-established option for permanent grounding and bonding work.

nVent CADDY GT1181GPLUS – Frequently Asked Questions

1) What is the nVent CADDY GT1181GPLUS used for?
The GT1181GPLUS is a CADWELD exothermic welding connector for permanent grounding and bonding connections on electrical systems. Instead of clamping conductors together, the CADWELD process fuses them into one continuous conductor at the joint. It is used for conductor-to-conductor and conductor-to-ground connections in commercial and industrial work, including utility, substation and data center grounding systems. It is not a general-purpose wiring splice.
2) Should I use an exothermic weld or a mechanical ground clamp for a grounding connection?
A mechanical lug or clamp relies on surface contact and applied torque, so over years it can loosen, climb in resistance, and corrode at the dissimilar-metal interface. The CADWELD process the GT1181GPLUS uses fuses the conductors into a single homogeneous conductor, so there is no mechanical interface to relax and no joint interface to drive galvanic corrosion. If the connection will be buried, inaccessible, or needs to stay low-resistance for the life of the installation, the exothermic weld is the right call. For connections you expect to open up and re-terminate later, a mechanical connector is the more practical choice.
3) Is the GT1181GPLUS a reusable tool or a one-shot connection?
It is a single, permanent connection configuration. The CADWELD exothermic process consumes weld material to fuse the conductors, so the resulting joint is not meant to be opened or re-made. Plan the grounding layout and conductor routing before welding, since a completed CADWELD joint has to be cut out rather than loosened.
4) How do I confirm the GT1181GPLUS matches my conductor sizes?
The GT1181GPLUS designation identifies one specific CADWELD connection configuration, and each configuration is tied to a particular conductor combination and weld metal charge size. Match the model designation on the drawing or the existing grounding detail to GT1181GPLUS rather than selecting by cable size alone, and confirm the conductor combination against the nVent CADDY catalog documentation for that configuration before welding.
5) Who should be making CADWELD exothermic grounding connections?
CADWELD connections like the GT1181GPLUS are intended for qualified electricians and contractors doing grounding and bonding work. The process involves igniting a weld charge inside a mold, so it belongs with crews trained on the CADWELD system rather than general maintenance staff.
6) Is the GT1181GPLUS part of the ERICO CADWELD line?
Yes. GT1181GPLUS sits in the CADWELD series from the nVent ERICO CADWELD line, now sold under the nVent CADDY brand of electrical connection, grounding and support products. If your spec calls out ERICO CADWELD, this is the same system.
