Top 5 Electrical Floor Trunking Mistakes to Avoid During Installation

Installing electrical floor trunking is an essential step in modern infrastructure, particularly for offices, retail spaces, and institutions. When done correctly, it ensures a safe, clean, and organized way to manage cables beneath the floor. However, several common mistakes during installation can compromise both the safety and functionality of your underfloor cable trunking system. To help you avoid these pitfalls, we’ve outlined the top five mistakes and how to prevent them.

One of the most common mistakes is starting installation without a well-thought-out plan. Proper planning involves mapping out where all the underfloor trunking will be placed based on the layout of the space. A poorly planned layout can result in excessive bends, inconvenient access points, or future obstructions.

How to Avoid:

• Assess the electrical needs of the space in advance. 
• Include expansion possibilities in the layout to avoid future rework. 
• Work closely with architects and interior designers to ensure alignment with the overall design.

Choosing substandard or incorrect-sized materials can lead to serious safety issues. Trunking that is too small will overcrowd cables, increasing the risk of overheating, while low-quality trunking may break under heavy floor traffic.

How to Avoid:

• Select durable electrical floor trunking made from high-quality materials like galvanized steel or aluminum.
• Ensure the trunking size matches the anticipated cable load to prevent overcrowding.

Installing underfloor trunking without considering accessibility can make future maintenance a nightmare. If access points are too few or poorly placed, it becomes difficult to modify or repair cables when needed.

How to Avoid:

• Install multiple access points for easy inspection and maintenance.
• Use modular underfloor cable trunking systems to allow for easy modifications.
• Label trunking sections clearly during installation to quickly identify cables and enhance the efficiency of your cable management system.

Even with the right trunking installed, improper cable management can lead to disorganization, signal interference, and safety hazards. Bundling cables together without separation can create electrical interference, affecting the performance of the system.

How to Avoid:

• Separate power and data cables within the trunking to avoid signal interference.
• Use cable ties, organizers, and other cable management solutions to keep the system neat and reduce stress on individual cables.
• Follow standard wiring regulations to ensure compliance and safety.
