Thomas Betts AT-3 T-body Conduit Body 1 Inch Imc Rigid

Product Description

The THOMAS BETTS AT-3 is an oval T-body conduit body designed for use with 1-inch trade size IMC and rigid aluminum conduit systems. It provides a junction point where conduit runs intersect in a T-configuration, allowing conductors to be pulled, spliced, or redirected without requiring a full junction box. The body offers 11.8 cubic inches of volume capacity and carries a weather-resistant rating, making it suitable for both interior and exposed exterior installations. Licensed electricians and electrical contractors install this fitting as part of a complete conduit assembly on commercial and industrial wiring systems.

This conduit body is rated for 1-inch trade size IMC and rigid conduit, covering the most common intermediate and heavy-wall metallic conduit types used in commercial, industrial, and institutional electrical work. Its oval profile fits standard conduit body covers and gaskets used in wet or damp location raceways. The AT-3 is appropriate for branch circuit and feeder conduit runs where a T-branch access point is required.

Compatibility

Designed as an OEM-style fitting for 1-inch trade size IMC and rigid metallic conduit systems in commercial and industrial electrical installations.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the NEC and applicable local codes. De-energize all circuits and verify with a meter before opening or working near the conduit system. Secure conduit bodies at the entry hubs using appropriate locknuts and bushings rated for the conduit type. Do not exceed the marked volume capacity when filling with conductors, as NEC Article 314 governs fill calculations for conduit bodies.
