nVent CADDY T416B HDPE Ground Inspection Housing, 13.1-Inch x 10-Inch

The nVent CADDY T416B is a durable HDPE ground inspection housing designed to protect and provide convenient access to exothermic Cadweld® ground connections. Measuring 13.1-Inch x 10-Inch, this housing is sized to accommodate ground rod and cable connection points for inspection, testing, and maintenance. Molded from high-density polyethylene (HDPE) for long-term durability outdoors and below grade, it is a practical, non-metallic solution for grounding electrode systems in commercial, industrial, and utility installations. Positioning the housing over a Cadweld® exothermic weld gives crews a marked, accessible location for future testing without repeated excavation around the connection point.

Key Features

  • Housing Dimensions: 13.1-Inch x 10-Inch footprint provides ready access to below-grade ground connection points.
  • Durable HDPE Construction: high-density polyethylene resists corrosion, moisture, and impact for long service life in outdoor and underground environments.
  • Cadweld® Compatible: sized and configured to house and protect exothermically welded (Cadweld®) ground rod and cable connections.
  • Inspection & Access Housing: gives electricians and utility crews a dedicated access point for inspecting, testing, and maintaining grounding electrode connections without excavation.
  • Non-Metallic Material: HDPE construction will not rust or corrode the way metal enclosures do, supporting long-term reliability of the grounding system.
  • Field-Ready Housing Profile: rectangular 13.1-Inch x 10-Inch shape sets over the exothermic weld location, simplifying installation and marking the connection for future technicians.

nVent CADDY T416B – Frequently Asked Questions

1) What is the nVent CADDY T416B ground inspection housing used for?
The T416B is a ground inspection housing that sets over a below-grade Cadweld exothermic ground connection, giving crews a marked, accessible point to inspect and test the connection later without digging it up again. It covers ground rod and cable connection points in grounding electrode systems on commercial, industrial, utility, and telecom sites.
2) What size opening does the T416B inspection housing cover?
The T416B has a 13.1 x 10 inch footprint, sized to sit over a ground rod and cable connection point. Lay out your excavation and weld location so the connection falls within that rectangle; if your ground bar or multiple cable runs spread wider than 13.1 inches, the housing will not seat over all of them.
3) Does the T416B housing work with Cadweld exothermic welds, or only mechanical connectors?
It is sized and configured for exothermically welded Cadweld ground rod and cable connections. The weld is made first, then the housing is set over the finished connection. A mechanical connector of similar size would physically fit under the same footprint, but the product is built around the Cadweld connection point.
4) Is the T416B ground box metal or plastic, and will it corrode underground?
It is non-metallic, molded from high-density polyethylene (HDPE). HDPE will not rust the way a metal enclosure does, and it resists moisture and impact in buried and outdoor service, which is why it gets specified for grounding electrode inspection points that stay in the ground for the life of the building.
5) Do I get the exothermic weld mold and consumables with the T416B?
No. The T416B is the housing only, ordered as a single model with MPN T416B. The Cadweld mold, weld metal cartridges, ignition, ground rod, and conductor are all separate items you order alongside it to complete the connection.
6) Can I use a ground inspection housing instead of a concrete test well?
Yes, for most grounding electrode inspection points. The HDPE T416B does the same job as a heavier concrete or metal test box, marking and protecting the connection while keeping it reachable, but it is lighter to carry and set, and it will not corrode. Concrete or cast iron is the choice where the cover sees vehicle traffic; the HDPE housing suits landscaped, yard, and equipment-pad locations.
7) Is one T416B enough for a multi-point grounding system, or do I need one per connection?
One per connection you intend to inspect. The 13.1 x 10 inch housing covers a single ground rod and cable connection point, so a substation or telecom site with several test points needs a housing at each location you want to reach later. Crews commonly cover only the connections the inspection plan calls out rather than every weld in the loop.
