Conduit cable, which you might also see listed as trunking cable, insulated cables, or armoured cable, refers to a length of wire or cabling intended to be run through a protective plastic or metal sheath. This protective channel is often called wire conduit or cable trunking. It may be rigid or flexible, depending on the needs of the installation.
Conduit or trunking is normally used for cable management systems where current needs to be carried between multiple devices and terminals. It’s especially useful in any potentially hazardous areas, whether the perceived hazard is environmental or physical. Ambient or weather-related conditions (e.g. moisture, extreme temperatures, etc) may be good reasons to choose conduit, trunking, and protective cable sleeving.
If conductors and cables need to be run across areas where they present a tripping or snagging hazard, floor trunking may offer some degree of protection for the physical wiring itself. However, conduit and trunking are most often used where cables will be elevated or hidden. For cabling running across an open floor surface, it can be more practical to use dedicated cable protectors and cable covers for safety.
Conduit and trunking are more often used where a raised/wall-mounted, embedded or partly concealed wiring run needs further protection. It also helps to clean up the overall appearance of your wiring as a handy cable management solution. Everyday examples include wiring runs going across ceilings, outdoor cabling, underground cable runs, or wires being chased into and around walls.
In these sorts of scenarios, using sheathed cables with trunking or conduit protection is a great way to guard against knocks, cuts, general damage/degradation, and environmental conditions. They also help protect anyone living or working in the vicinity from accidental exposure to current and voltage.
In this expert guide, we’ll cover the basics of cable conduit, including what types are available to buy online in the UK. We’ll also talk briefly about how to cut and install trunked cable indoors, on walls, and outside. To begin with, we’ll outline the relationship, similarities and differences between cable trunking and cable conduit.
