Common Mistakes in Cable Containment

What is Cable Containment and Why Does it Matter?

Cable containment is the process of safely routing and supporting cables using systems specifically designed to protect and organise electrical installations. Common cable containment solutions include cable trays, cable baskets, cable ladders, trunking and channel support systems. These products keep cables securely in place, helping prevent damage, minimise disruption and create a safer, more organised and professional-looking installation.

8 Common Cable Containment Mistakes 

Choosing the Wrong System for Your Project

One of the most common mistakes is selecting a containment system that doesn’t suit the application. For example, cable baskets may be ideal for lightweight data cabling, but using them for larger industrial cables can place excessive strain on the system, potentially leading to sagging or failure. Always consider cable type, weight, installation environment and load requirements to ensure you choose the most appropriate containment solution for your project.

Heavy-duty industrial power cables will often require cable ladders or trays with greater load-bearing capacity, but if you’re not certain, consult with a professional about the best containment solution.

Underestimating Expansion Capacity

Many installations are designed only for current cable requirements, leaving little room for future additions. As systems expand, overcrowded containment can make maintenance more difficult and increase the likelihood of replacing entire sections.

Allowing spare capacity from the outset provides flexibility for future upgrades without major disruption or additional installation costs.

Overloading Cable Trays and Baskets

It may seem like an efficient way to reduce the amount of cable containment required, but exceeding the load capacity of cable trays and baskets can cause sagging, damage and premature system failure. Always calculate cable loads accurately and choose containment systems designed to support both current requirements and future expansion.

Failing to Plan Cable Routes Beforehand

Cable containment systems are generally straightforward to install, but failing to plan cable routes beforehand can lead to unnecessary costs, wasted materials and inefficient layouts. It can also make future maintenance and system expansions more difficult. Plan your cable routes to maximise available space, minimise unnecessary bends and allow sufficient capacity for future upgrades.

Not Separating Power and Data Cables  

Another common mistake is failing to separate power and data cables. While it may seem like a way to save time during installation, running them together can cause electromagnetic interference, affecting network performance and signal quality. Using dedicated containment systems or suitable dividers helps minimise interference while creating a safer, more organised installation.

Ignoring Environmental Conditions

Environmental conditions play an important role in selecting the right cable containment system. Ignoring factors such as moisture, heat or corrosive environments can result in a system that isn’t suitable for the application, leading to reduced performance and a shorter lifespan. Choose cable containment products made from materials and finishes designed to withstand the conditions they’ll be exposed to.

Not Using Correct Fixings and Accessories

Whether it’s an oversight, an attempt to reduce costs or underestimating cable loads, not using the correct fixings and accessories is a common, yet avoidable mistake. Inadequate support may reduce load capacity or compromise system stability over time. Always use compatible accessories recommended for the specific containment system to achieve a secure and reliable installation.

Blocking Airflow Around Cabling 

Packing cables too tightly or completely filling containment systems can restrict airflow, making it more difficult for heat to dissipate. Excessive heat can build up over time and reduce cable performance and contribute to premature cable deterioration. Maintaining appropriate spacing between cables helps improve ventilation. It also enables easier access for inspections and future modifications.

The Effects of Cable Containment Mistakes

Mistakes during planning or installation can have lasting consequences throughout the life of an electrical system, including:

• Increased maintenance costs due to a lack of accessibility
• A complete overhaul, resulting in spending more on an installation
• An increased chance of cable damage due to poor system organisation 
• Poor signal strength due to electromagnetic interference
• Higher long-term project costs due to avoidable repairs
