Ever wonder what protects all those wires running through buildings and job sites? 

Conduit is the backbone of safe electrical installations. Choosing the right type matters — not just for performance, but also for meeting code. 

Curious about how electrical systems are put together? Learning about conduit is a smart first step. Employers expect technicians to know which conduit to use, how to install it and how to stay compliant, which is why Universal Technical Institute (UTI) includes conduit fundamentals in its hands-on electrical training, preparing students for real-world career opportunities.130 

Keep reading to break down the most common types of electrical conduit — electrical metallic tubing (EMT), polyvinyl chloride (PVC) and flexible metal conduit (FMC) — and see how UTI helps aspiring techs build these skills. 

What Is Electrical Conduit and Why It Matters

Protection, routing and code basics 

Conduit is tubing that surrounds and protects wires. It shields against physical damage, keeps wiring organized and makes it easier to pull or replace conductors. The National Electrical Code (NEC) sets strict rules on what type of conduit to use in different conditions to prevent hazards. 

Indoor vs. outdoor considerations 

Environment matters. Indoors, lightweight conduit may be acceptable. Outdoors or underground, you would need materials that resist moisture, heat or impact. Choosing the wrong type can mean failed inspections or unsafe systems.

EMT Conduit: Where and Why It’s Used 

Characteristics, fittings and bending basics 

Electrical metallic tubing (EMT) is thin-walled steel or aluminum. It’s strong yet easy to bend with a hand bender. Couplings and set-screw fittings secure it together. 

Pros and cons in commercial work 

  • Pros: Affordable, reusable and approved in most indoor commercial spaces. 
  • Cons: Not suitable for corrosive or outdoor wet locations without extra protection.

PVC Conduit: Uses and Limitations 

Schedules, glue joints and sunlight ratings 

Polyvinyl chloride (PVC) conduit is plastic. It comes in Schedule 40 (lighter) and Schedule 80 (thicker). Solvent cement bonds the joints. Some types are marked “sunlight resistant” for outdoor use. 

Pros and cons for wet locations 

  • Pros: Corrosion-proof, low-cost, lightweight and common in underground or wet applications. 
  • Cons: Brittle in cold weather, cannot be bent without heat and not fire-resistant.

Flexible Metal Conduit (FMC and LFMC) 

When flexibility is required 

Flexible metal conduit (FMC) is spiral-wound metal that bends easily, making it ideal for tight spaces, machinery and retrofits. Liquidtight flexible metal conduit (LFMC) adds a plastic coating for damp or outdoor areas. 

Bonding and grounding considerations 

Because FMC uses metal coils, grounding is critical. NEC requires proper fittings to ensure continuity and reduce shock risk.

Choosing the Right Conduit 

Environment, load and inspector expectations 

The jobsite tells you what to pick. Moisture, heat and physical stress all affect selection. Inspectors look for code-compliant installs, so planning ahead saves time and rework. 

Planning bends, pulls and box fill 

Think ahead about how many bends are allowed in one run and whether wires can be pulled without damage. Overfilled boxes or too many bends can cause failed inspections and tough troubleshooting later.

Learn Conduit Types and Uses 

Hands-on electrical training 

Through training in wind energy, robotics and automation, industrial maintenance or electronics, Universal Technical Institute helps students build skills cutting, bending and fitting conduit in lab settings. You won’t just read about conduit — you can install it using real tools. 

Building career-ready skills in about a year or less 

In a year or less, you can train for entry-level roles in industries that rely on electrical systems every day.130 From routing conduit to troubleshooting circuits, you can practice skills employers expect. 

Electrical Training To Learn Different Types of Electrical Conduit 

To repair electrical systems, you need to know the right conduit types and uses and be able to install them safely. With hands-on training at UTI, you can practice using EMT vs. PVC conduit and flexible metal conduit before stepping out into the real world.
