Cable Management
Securing connections
I
n the rapidly evolving world of electrical installations, effective cable management is no longer a mere aſterthought - it’s a fundamental component of system reliability, safety and serviceability. Conduit plays a crucial role in cable management by providing protection, organisation and routing for electrical wiring and cables.
Key functions of conduit include protection – mechanically protecting cables from physical damage, moisture, chemicals and environmental factors. This also reduces the risk of faults, such as short circuits and access to potential live parts. As well as mechanically protecting cables, conduit helps maintain a neat and organised wiring system. This systematic routing of cables prevents clutter and simplifies future maintenance or troubleshooting activities. When selecting the use of a conduit system it is essential that the conduit accessories used are installed correctly to ensure adherence to the relevant electrical standards, which is vital for all types of installations.
Understanding the functionality of conduit accessories
Conduit accessories - such as connectors, couplings, elbows, straps, saddles and junction boxes - play a pivotal role in complementing conduit runs, ensuring secure, safe and efficient routing of electrical wiring.
These components serve several key functions. They provide mechanical continuity - couplings and connectors ensure seamless conduit runs, preserving structural integrity and maintaining the physical protection of cables across transitions and terminations. They also ensure safety and compliance. Grommets and insulating fittings protect conductor insulation from abrasion at entry points, directly contributing to NEC and IEC compliance and reducing the

risk of arc faults or short circuits. Flexibility and accessibility are other key functions; junction boxes and access fittings allow for future system modifications and troubleshooting, significantly reducing downtime during maintenance. Conduit accessories also offer support and strain relief: conduit straps, clamps and hangers help distribute mechanical loads and prevent conduit sagging, thereby maintaining the integrity of the entire cabling infrastructure.
Enhancing installation efficiency Conduit accessories are also essential for improving installation efficiency. For instance, quick-connect couplings and tool-free locking mechanisms can reduce labour hours and increase the speed of deployment - especially critical in large-scale commercial or industrial projects. Additionally, colour-coded or pre- threaded fittings reduce onsite preparation time and improve accuracy in complex installations, such as those found in data centres or mission- critical environments.

Mike Jackson, sales director, with Scolmore Group company, Unicrimp, looks at the critical role that conduit accessories play in cable management systems.
Material and application considerations Different environments demand different materials. For example metal accessories (e.g., galvanized steel or brass) are ideal for high- temperature or industrial environments due to their durability and resistance to corrosion. PVC and nylon fittings offer corrosion resistance in damp or chemically aggressive settings and are lightweight for ease of installation. Explosion-proof and watertight accessories are vital in hazardous areas, ensuring protection against gas ingress, dust and water under pressure. Choosing the correct accessories based on material, ingress protection (IP) rating and fire resistance is crucial for both performance and safety.
Q-Crimp conduit accessories Unicrimp recently added a comprehensive collection of conduit accessories to its Q-Crimp product portfolio. The range of conduit fittings and accessories has been designed to offer durability and ease of installation. Unicrimp’s conduit accessories ensure that installations comply with safety regulations and standards, such as IET Wiring Regulations. Both indoors and outdoors, whether in commercial buildings, large-scale industrial settings or residential homes, conduit accessories are the unsung heroes that keep everything together and ensure safety.
The Unicrimp range comprises more than 90 individual products, with key products including conduit boxes, light gauge saddles, inspection tees, inspection bends and metal hooks. Conduit boxes - also known as BESA boxes - are designed to protect and route electrical cables within building structures. The new range includes 1 Way, 2 Way, 3 Way and 4 Way Conduit Boxes, available in a variety of Angled, Tangent, ‘U’, ‘Y’ and ‘H’ shape configurations. Light gauge saddles are designed to wrap securely around conduits, providing precise support for the wiring system. Featuring a BZP (bright zinc plated) coating, these saddles are resistant to rust and oxidation, ensuring long- term durability.
