- Typical Applications: Outdoor installations, underground runs, and areas requiring maximum physical protection.
Intermediate Metal Conduit (IMC)
- Description: Similar to RMC but with a thinner wall, making it lighter and easier to work with.
- Advantages: Offers good protection at a lower cost than RMC.
- Disadvantages: Less durable than RMC.
- Typical Applications: Indoor and outdoor installations where RMC is overkill but EMT is insufficient.
Electrical Metallic Tubing (EMT)
- Description: Thin-walled conduit, often referred to as "thin-wall."
- Advantages: Lightweight, inexpensive, and easy to cut and bend.
- Disadvantages: Not suitable for environments with significant physical stress or moisture exposure.
- Typical Applications: Indoor installations in dry locations.
Flexible Metal Conduit (FMC)
- Description: Helically wound, flexible metal conduit.
- Advantages: Allows for bends and changes in direction without the need for elbows.
- Disadvantages: Less protective than rigid conduits.
- Typical Applications: Connecting motors, lights, and other equipment where flexibility is required.
Liquidtight Flexible Metal Conduit (LFMC)
- Description: FMC with a liquidtight, non-metallic covering.
- Advantages: Provides flexibility and protection against moisture and corrosive substances.
- Disadvantages: More expensive than standard FMC.
- Typical Applications: Outdoor installations and damp or wet locations.
Non-Metallic Conduit (PVC)
- Description: Rigid or flexible conduit made of polyvinyl chloride (PVC).
- Advantages: Lightweight, corrosion-resistant, and easy to cut and join.
- Disadvantages: Less resistant to physical damage and not suitable for high-temperature environments.
- Typical Applications: Underground installations, corrosive environments, and residential wiring.
Essential Tools for Conduit Runs
A well-equipped toolbox is crucial for successful conduit run installation.
- Conduit Bender: (Manual or hydraulic) Used to create precise bends in conduit.
- Conduit Cutter: For cleanly cutting conduit to the desired length. A hacksaw can also be used.
- Reamer: To remove burrs and sharp edges from the cut end of the conduit.
- Fish Tape: Used to pull wires through the conduit run.
- Tape Measure: For accurate measurements.
- Level: Ensures conduit runs are straight and level.
- Markers: For marking cutting and bending points.
- Screwdrivers and Wrenches: For tightening fittings and connectors.
- Pliers: For various tasks, such as gripping and cutting wire.
- Safety Glasses and Gloves: Essential for personal protection.
Planning Your Conduit Run: A Step-by-Step Guide
Proper planning is essential for a smooth and efficient conduit installation.
- Map the Route: Determine the optimal path for the conduit run, considering obstacles and accessibility.
- Calculate Conduit Length: Measure the length of each conduit section, including bends and offsets.
- Choose the Right Conduit Type: Select the appropriate conduit type based on the environment and application.
- Determine Support Spacing: Follow code requirements for conduit support spacing to prevent sagging and ensure stability. Refer to local electrical codes.
- Plan for Pull Points (If Necessary): For long runs, incorporate pull boxes or access points to facilitate wire pulling.
- Prepare Materials: Gather all necessary conduit, fittings, connectors, and supports.
Mastering Conduit Bending Techniques
Bending conduit accurately is a crucial skill for any electrician.
Understanding Bending Angles
- Common Bends: 90-degree bends, offsets, saddles.
- Using a Bender: Proper technique to create accurate bends with minimal deformation.
- Calculating Bend Allowance: Accounting for material stretch during bending.
Step-by-Step Bending Instructions
- (Example: 90-degree bend):
- Mark the desired bend location on the conduit.
- Position the conduit in the bender with the mark aligned with the bending arrow.
- Apply consistent pressure and gradually bend the conduit to the desired angle.
- Verify the angle with a protractor or level.
Tips for Successful Bending
- Practice makes perfect: Use scrap conduit to hone your bending skills.
- Use the right tools: Choose the appropriate bender for the conduit type and size.
- Bend gradually: Avoid excessive force, which can damage the conduit.
- Double-check your measurements: Accuracy is essential for proper fit.
