Trunking vs. Conduit — What's the Difference?
By Tayyaba Rehman — Updated on October 6, 2023
Trunking is a system for enclosing cables in buildings, while Conduit refers to tubes that protect and route electrical wiring. Both aid in organizing and protecting wires.

Key Differences
Trunking is primarily an enclosure system that houses and organizes cables, often seen in office environments or data centers. Its main focus is to keep multiple cables tidy and easily accessible. Conduit, on the other hand, is a tube or tunnel-like structure, typically made of metal or plastic, designed to protect and route electrical wires.
While both Trunking and Conduit serve the purpose of housing cables or wires, their application differs. Trunking systems are generally surface-mounted and might be visible, providing ease of access to cables for maintenance or reconfiguration. Conduits, conversely, are often embedded within walls, floors, or ceilings, making the wires they contain less accessible but more protected.
From a material perspective, Trunking systems can be made of various materials, including metal, plastic, or wood. They often come with removable covers to access the cables inside. Conduit is typically made of rigid or flexible metal, PVC, or other durable materials that ensure the protection of the wires inside from external damages.
Aesthetic considerations also differ between Trunking and Conduit. While Trunking is designed for easy accessibility and can be seen in modern office environments, it might not always be the most aesthetically pleasing. Conduit systems, being concealed within structures, offer a more polished look, keeping wires entirely out of sight.
Lastly, the term Trunking also finds use in telecommunications to refer to a method where multiple signals are bundled together. Conduit remains specific to its definition, referring to the protective tubing for electrical or communication cables.
