Conduit Body

What is Conduit Body?

A conduit body is a fitting that provides access to electrical conduit systems for wire pulling, splicing, and maintenance.

Description

A conduit body is a cast or formed fitting used in electrical conduit systems to allow access for pulling, splicing, or inspecting conductors. It typically includes a removable cover, making it possible to reach wires at points where conduit changes direction or where long runs require access for installation and maintenance.

Conduit bodies are commonly used in both commercial and industrial construction, especially where rigid metal conduit (RMC), intermediate metal conduit (IMC), or electrical metallic tubing (EMT) is installed. They are available in various shapes—such as LB, LL, LR, T, and C—each designed to accommodate specific conduit routing configurations and space constraints.

From a code and installation perspective, conduit bodies must be properly sized to allow safe wire bending radii and comply with electrical codes. Covers must remain accessible after installation and are often gasketed for weatherproof or dust-tight applications. When correctly installed, conduit bodies improve system serviceability while maintaining electrical safety and compliance.

FAQs

  • What is a conduit body used for?

    A conduit body provides access to conductors for wire pulling, inspection, splicing, and maintenance within a conduit system.

  • What do LB, LL, and LR conduit bodies mean?

    These designations indicate the direction of the conduit opening and access cover relative to the conduit run.

  • Are conduit bodies allowed to contain wire splices?

    Some conduit bodies are approved for splicing, but this depends on their size, volume, and code compliance.

  • Do conduit body covers need to be accessible?

    Yes, electrical codes require conduit body covers to remain accessible after installation.

  • Are conduit bodies weatherproof?

    Many conduit bodies are rated for outdoor use and include gasketed covers to resist moisture and dust.

Fun Fact

The letters used to label conduit bodies (like LB or LR) describe the shape and direction of the fitting, making it easy for electricians to identify them at a glance on-site.
