Product Information

Unfortunately, there’s no single rule for how to install it correctly - knowing how to install cable trunking and mini trunking is about understanding which type of product you’re buying, and what you need it to do.

Before completing the project, test all the cables to ensure they function correctly. This step is crucial to avoid future issues. 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. The first step in installing slotted finger trunking is to measure and plan the installation area. Identify where the trunking will be placed and measure the length accurately. Mark the spots where the trunking will be fixed, ensuring they are level and well-aligned.

Conduit is typically the cheaper and more basic approach to wiring protection. It’s widely used wherever smaller cable bundles or individual wires are being run between two terminals, from point A to point B. If they simply need to be protected, tidied up, and/or hidden from view, conduit is often the easiest option. Thanks for the video link. That was most helpful. I've had a go at making a diagram. I made a strip like you and then folded it. When folded the top will run from D to E and the bottom G to C to F to H. The dotted lines show where the strip is folded. Of course, the strip doesn't look like the diagram (as it is straight) but, hopefully, what I've done is how you want to construct your trunking. Galvanised trunking is a popular choice for organising and protecting electrical cables in various settings. Its durability and corrosion resistance make it an ideal solution for both residential and commercial installations. Slotted finger trunking is primarily designed for indoor use. If you need to install it outdoors, choose a weather-resistant version.

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. Remember to leave space (between D-Line lengths) to accommodate accessory required. For smooth-fit accessories, including connectors for all sizes, use the accessory as the template. Pencil mark the surface and the length, to indicate precisely where the trunking needs to be reach. After installing the lengths, and inserting the cables, the smooth-fit accessory will retro-fit into the space(s) you left. To calculate the size of the cut-out in the cable tray in this situation you divide the distance between sets by the width of the cable tray ie. 1500 ÷ 600 = 2.5, then divide the amount of off-set by 2.5, ie. 350mm ÷ 2.5 = 140mm. To get the most accurate results, while the set will be close, it is always best to do the first set then calculate where to do your parallel set cut by positioning the tray. Your way: You still have to make the spacer, you still have to cut holes in it to match the holes in the enclosure, you've MORE work to do to fix it since many materials will sag and open up a gap (IP4x gone) if not fixed as close intervals, and then you have to fix two short pieces of trunking on an uneven wall that's a PITA to fix things to (no, you really can't drill drill a hole and pop a plastic plug in) and make sure you get them aligned.

Introduction 

Electrical wiring outside is classed as a special area, under part P of the building works. We would not advise any electrical DIY works be conducted in a special location unless done by a professional. If the work is done badly you could injure or kill yourself or others. Choosing the right skirting trunking is a crucial decision that impacts your installation's efficiency, safety, and aesthetics. By considering factors such as cable capacity, material durability, cable segregation, and installation ease, you can ensure a seamless fit between the trunking and your project requirements. Remember, skirting trunking isn't just a practical solution; it's a design element that enhances the space's overall appeal. So, take the time to assess and make an informed choice for a successful installation. Choose skirting trunking with accessible covers or hinged designs for easy cable modifications or maintenance. Start by measuring the wall length where you intend to install the skirting trunking. Mark the areas where the trunking will be positioned using a pencil. i am trying to learn how to accurately measure and cut cable tray and trunking to be able to fabricate my own angles.

Yes you can. So long as you use a bonding coat, you can plaster directly over Trunking, keeping cables hidden and out of reach. Whether it’s Trunking or conduit you’re looking to plaster over, you should always make sure they’re deep enough in the walls to be covered by a full coat of plaster. The other common calculation you need is when you have to work out the amount of set required to make a parallel off-set eg when you have to set a cable tray or gutter around a pillar or set to an off-set wall. As such, consider that often the cost of replacement wire of the right length can be cheaper (and safer) than buying a kit to join armoured cables. Step 7: Lay the cable There are nine key stages involved in running the cable, which we will cover in more detail below. It’s worth highlighting at this stage that this is very complicated work and if you’re not familiar with electrics there is a real risk of harming yourself or others. First, work out a 90 degree right angle at the point of the Trunking you want to cut. Then find the middle point of that and mark it on your Trunking. Draw a triangle between the top point of the angle and the 45 degree points either side.

How can I run an armoured cable to my shed?

What I would do is use a spreadsheet program like Excel by Microsoft to make up the right formulas. Then you can easily plug in new values when you want. I'll show mine below. Alternatively, a specialist can look at this scope of work when building a new outbuilding. Our outbuilding cost guide goes into this in more detail. How can I run an armoured cable to my shed? If you're considering installing galvanised trunking, this step-by-step guide will walk you through the process and help you achieve a successful installation. Choosing the right size of slotted finger trunking depends on the number and size of cables you need to manage. Measure the cables' diameter and add some extra space for future additions. Depending on the trunking type, cable conduit size, cross-sectional area, amounts of cable and install location, you may need several additional tools to complete the installation. These can range from screwdrivers and drills to saws, putties and sealants, stud finders (wall scanners), and various others besides.
