Trunking vs. Conduit: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Trunking is a system for housing and protecting electrical cables, while a conduit is a tube through which cables are run for protection and routing.
Key Differences
Trunking typically refers to an enclosed channel, often made of metal or plastic, designed to protect and conceal electrical wires and cables. It is more substantial and can accommodate a larger volume of wires. Conduit, on the other hand, is a type of tubing, usually cylindrical, used to encase and protect individual electrical wires. It is often made of metal, plastic, or fiber and provides a pathway for electrical wiring.

Trunking systems are generally easier to install, offering more flexibility in terms of access as they can be opened for adding or removing wires. This makes them ideal for environments where wiring needs may change over time. Conduit systems are more permanent. Once the wires are enclosed, access is more difficult, making them a better choice for areas where the wiring does not need frequent changes.

Trunking is designed to manage a larger number of wires and cables, making it suitable for complex electrical installations like data centers or large buildings. Conduit is typically used for smaller-scale applications, ideal for single or fewer wires, often seen in residential or light commercial settings.

Trunking provides robust protection for wires and cables, shielding them from external damage and reducing the risk of electrical hazards. Conduit offers more focused protection for individual wires, safeguarding them from external elements and ensuring safety within the enclosed space.

Trunking can be more visually intrusive but is easier to adapt and scale in commercial or industrial settings. Conduit tends to be less noticeable, blending into the structure, and is commonly used in both visible and concealed applications.
