Module 1 - Lesson 3 Part 5: Conduits

Conduits

A protective tubing system used to enclose and route electrical wiring in buildings and structures.

Conduits

It provides mechanical protection, insulation, and organization for electrical conductors.

Rigid Steel Conduit (RSC)

• Galvanized Steel

• Maximum protection, durable, corrosion-resistant

• Expensive, heavy, difficult to install

Rigid Steel Conduit (RSC)

Usage: Heavy-duty industrial, commercial, and exposed areas

Intermediate Metal Conduit (IMC)

• Steel

• Lighter than RSC, still provides strong protection

• Requires threading, not as flexible as EMT

Intermediate Metal Conduit (IMC)

Usage: Commercial and industrial installations

Electrical Metallic Tubing (EMT)

• Thin-walled Steel

• Lightweight, easy to bend, cost-effective

• Not for wet or hazardous locations

Electrical Metallic Tubing (EMT)

Usage: Commercial, residential indoor, lighting

Rigid Non-Metallic Conduit (PVC)

• PVC

• Corrosion-resistant, waterproof, lightweight

• Brittle under impact, not fire-resistant

Rigid Non-Metallic Conduit (PVC)

Usage: Underground, wet locations, residential wiring

High-Density Polyethylene (HDPE)

• HDPE

• Highly durable, resistant to corrosion and chemicals

• Not for high-mechanical impact areas

High-Density Polyethylene (HDPE)

Usage: Underground, telecom, high-power installations

Aluminum Conduit

• Aluminum

• Lightweight, corrosion-resistant, grounding option

• More expensive than PVC, not as durable as steel

Aluminum Conduit

Usage: Residential, light-duty commercial use, exposed wiring

Flexible Metal Conduit (FMC)

• Steel/Aluminum

• Pre-wired

• Flexible, easy to install

• Not for long easy runs, not suitable in tight spaces for high-power circuits

Flexible Metal Conduit (FMC)

Usage: Short runs, machinery, vibration-prone areas

Liquidtight Flexible Metal Conduit (LFMC)

• Coated Steel/Aluminum

• Pre-wired

• Waterproof, flexible, durable, provides grounding

• Expensive, more rigid than FMC

Liquidtight Flexible Metal Conduit (LFMC)

Usage: Wet locations, outdoor, machinery, HVAC systems

Liquidtight Flexible Non-Metallic Conduit (LFNC)

• Non-metallic (PVC)

• Pre-wired

• Waterproof, flexible, corrosion-resistant

• Expensive, not for heavy-duty applications

Liquidtight Flexible Non-Metallic Conduit (LFNC)

Usage: Wet locations, exposed areas, light-duty applications

Flexible Non-Metallic Conduit (FMC - Non-Metallic)

• PVC

• Plain Conduit or Pre-wired

• Lightweight, easy to install, flexible

• Not suitable for high-power or outdoor applications

Flexible Non-Metallic Conduit (FMC - Non-Metallic)

Usage: Temporary wiring, low-power applications, light-duty

Surface Raceway

• PVC - Plain Conduit

• Rigid, lightweight, easy to install

• Suitable for exposed surface installations

Surface Raceway

Usage: Retrofit or renovation projects
