In what situation is trunking used and not conduit?

Trunking is typically used in situations where there is a need to manage and protect multiple cables in a tidy manner, such as in commercial or industrial environments where numerous electrical or data cables are routed along walls or ceilings. Unlike conduit, which encases individual wires for protection, trunking allows for easier access to cables for maintenance and modifications, making it ideal for installations that may require frequent changes. Additionally, trunking often offers a more aesthetically pleasing solution for visible cabling compared to conduit systems.
