In electrical work, conduiting refers to the process of enclosing electrical wires or cables within a protective tube or pipe, typically made of metal or plastic. This conduit serves as a channel to route and safeguard the wiring from damage and environmental hazards. It's commonly used in exposed areas, unfinished spaces, and outdoor installations.
Here's a more detailed explanation:
Purpose:
Conduits provide several benefits, including:
Protection: They shield wires from physical damage, moisture, corrosion, and other environmental factors.
Organization: Conduits help organize wiring runs, making them easier to maintain and troubleshoot.
Safety: They reduce the risk of electrical hazards, such as shorts and electrical shocks, by containing the wiring.
Code Compliance: Conduits are often required by electrical codes, such as the National Electrical Code (NEC), for specific applications and environments.
Types of Conduits:
Rigid Metal Conduit (RMC): A strong, threaded conduit typically made of steel, used for outdoor and heavy-duty applications, and providing structural support.
Electrical Metallic Tubing (EMT): A thinner, flexible conduit, often used for exposed wiring within buildings.
Flexible Metal Conduit (FMC): A flexible conduit that allows for easier routing in tight spaces.
Rigid Non-Metallic Conduit (RNMC): Made of PVC or other plastics, offering chemical resistance and moisture resistance.
Liquidtight Flexible Non-Metallic Conduit (LNFC): Specifically designed for wet or corrosive environments.
Installation:
Conduits are installed using a variety of fittings, such as elbows, couplings, and connectors, to create a continuous run. They can be installed before or after wiring is pulled through.
Applications:
Conduits are used in various settings, including:
Residential: For wiring in attics, crawlspaces, and outdoor installations.
Commercial: In factories, warehouses, and other industrial facilities.
Industrial: In hazardous locations and environments requiring specific protection.
