Conduit Bodies & Entrance Caps

What Is a Conduit Body & Entrance Cap?

A conduit body is a type of fitting that provides access to the interior of a conduit system for pulling, splicing, and maintaining electrical wires. Conduit bodies are essential for protecting wiring and ensuring easy access points throughout the system. You’ll commonly find conduit bodies in configurations such as LB, LL, LR, T, and C, each serving different directional needs.

A service entrance cap (also known as an entrance cap or electrical entrance cap) is used at the termination point of a conduit, typically where electrical service enters a building. It protects conductors from moisture, debris, and environmental exposure while allowing cables to exit safely.

Both conduit bodies and service entrance caps are critical components in building safe and code-compliant electrical installations.

Where Are They Used?

Conduit bodies and entrance caps are widely used across multiple types of electrical systems:

Residential installations – for routing wiring through walls, ceilings, and exterior entry points
Commercial buildings – ensuring organized and accessible conduit runs
Industrial environments – protecting wiring in harsh or outdoor conditions
Service entry points – where an electrical entrance cap or service entrance caps are required to safely guide cables into a structure

A properly installed conduit body simplifies maintenance and reduces the need for complex conduit bending. Meanwhile, service entrance caps and electrical entrance caps are essential for preventing water ingress and extending the lifespan of your electrical system.

How to Choose the Right Product

Selecting the right conduit bodies and entrance caps depends on several key factors:

1. Material Type. Choose between aluminum, steel, or PVC depending on the environment. PVC conduit bodies are corrosion-resistant, while metal conduit bodies offer superior durability and grounding capabilities.

2. Size & Compatibility. Ensure the conduit body or entrance cap matches the diameter and type of your conduit system (EMT, rigid, or PVC).

3. Application Environment. For outdoor or wet locations, select weatherproof service entrance caps or electrical entrance caps designed to resist moisture and UV exposure.

4. Configuration. Different conduit bodies (LB, LL, LR, etc.) are used based on directional changes in your conduit run. Always choose the correct shape to minimize installation complexity.

5. Compliance. Make sure all conduit bodies and service entrance caps meet Canadian electrical code requirements for safety and performance.
