Dado Trunking: The Ultimate Guide

Dado trunking, a versatile and practical solution for managing cables in any space, is a crucial aspect of electrical installations and home improvement projects. Whether you're tackling a residential or commercial project, understanding the ins and outs of dado trunking is essential to ensure a safe, organized, and aesthetically pleasing result.

What is Dado Trunking?

Dado trunking is a type of electrical wiring system that consists of a hollow channel or enclosure that runs along the lower part of a wall, typically at the height of the skirting board. It provides a concealed pathway for electrical cables, ensuring a neat and professional finish while protecting them from damage.

Types of Dado Trunking

Various types of dado trunking cater to different needs and applications:

• Mini Trunking: A compact option suitable for low-voltage cables, such as telephone and data cables.
• Standard Trunking: A medium-sized alternative for handling power cables and larger bundles.
• Maxi Trunking: A robust and spacious choice for high-power cables and complex installations.
• Skirting Trunking: A combined solution that incorporates dado trunking with a skirting board, providing aesthetics and functionality.
• Floor Trunking: A specialized type that runs along the floor instead of the walls, offering a discreet and low-profile option.

Benefits of Using Dado Trunking

Dado trunking offers several advantages compared to traditional wiring methods:

• Concealed Cables: Hides unsightly cables from view, creating a clean and organized appearance.
• Protection from Damage: Encases cables within a protective enclosure, shielding them from potential impacts, dust, and moisture.
• Flexibility: Allows for easy cable access and future upgrades without the need for disruptive rewiring.
• Improved Safety: Ensures cables are safely managed, reducing the risk of electrical hazards.
• Cost-Effective: A cost-effective alternative to traditional conduit or surface-mounted wiring.

How to Install Dado Trunking

Installing dado trunking involves the following steps:

1. Planning and Measurement: Determine the cable routing and measure the required length of trunking.
2. Marking and Cutting: Mark the wall at the appropriate height and use a hacksaw or miter box to cut the trunking to length.
3. Drilling and Mounting: Drill pilot holes and use screws to secure thetrunking to the wall. Ensure the trunking is level and aligned.
4. Inserting Cables: Feed the cables into the trunking using a cable pulling tool or fish wire.
5. Closing and Sealing: Snap the lid onto the trunking and use sealant or adhesive tape to secure the joints for a professional finish.

Effective Strategies for Installing Dado Trunking

• Plan the cable routing carefully to avoid unnecessary bends or crossovers.
• Use a spirit level to ensure the trunking is perfectly horizontal.
• Tighten the screws securely to prevent the trunking from becoming loose.
• Leave extra slack in the cables to allow for future additions or replacements.
• Consider painting the trunking to match the wall color for a seamless aesthetic.
