The leads also are usually very slim making them perfect for routing behind walls and in thin gaps. If you still can feed it through a thin gap you can always cut of the mains plug and fit a new one at the bottom. A downside of doing this way is that if you ever change your TV you might not be able to use the cable you have installed. The cables can be spliced if this is the case and you can buy specialist connectors for doing this, also adapters exist for this purpose. If you do you need to make sure that you have protected the cable with the right sized fuse as different cables have different amp carrying capacities. Most new TV’s have detachable power leads so a longer one can just be connected. These are usually either a figure 8 mains cable, a cloverleaf cable or a IEC kettle lead. Sometimes your TV will come with a transformer that connects to the TV. This is still usually fine as most of the time the transformer will accept one of the cable types mentioned above and the transformer can usually be slotted in behind the wall mounted TV.
Whenever you see wall mounted TV’s in shops or on the TV, you never see any attaching dangling cables or the effort that went into hiding them. If you’re buying a new TV, even if you do not intend to use it for live TV through a TV aerial or satellite dish and only intend to watch streamed on demand content. You will still at least need to get a power cable up to the TV. This blog discusses some of the ways of doing this. This could be routed in the wall or installing within trunking. If you want to know more about concealing TV wires I recommend our previous blog on how to do so. Where installing mains cabling this should be within the safe zones, which mean that cables should either be installed horizontally or vertically to entry/ exit points. Where routing cables in walls, consider installing the mains cable into a trunking/ conduit to allow you to pull cables to the TV at a later date without having to disturb the plaster.

Another option for TV power when on the wall is to install a fused spur unit behind the TV position. This may too mean having to employ an electrician to do this for you if you’re not competent/ confident working with electrics. I strongly advise not doing so if you’re not. I have to admit that this is my preferred option where possible. This is because in the UK you’re not limited to the amount of fused spurs you can install on a ring main,obviously providing that this doesn’t overload the circuit. So you won’t need to alter the existing ring main, you can just spur off of it. The biggest thing of all the consider also is whether your TV can actually accept a detachable cable. If it has a molded mains lead then you will not be able to do it this way. The C7 is a 2 pin power connector in the shape of a figure 8, some equipment uses keyed or polarised versions but the standard figure 8 connector will fit these. Angled Figure 8 Power Cables are also available where space is at a premium such as mounting TVs flat on a wall.
Make sure that the cables are being protected with an appropriately sized fuse. This is especially important when connecting into fused spur units. The C15 connector is similar to a C13 but has an extra notch in the connector, C15 Power Cables are referred to as hot connector as they havea higher temparture rating.Another thing that I commonly do for customers and clients is to just provide and install a longer power lead for the TV than the one that comes with the TV. More often that not when installing TV’s on walls you have to think of other factors like getting aerial cables and HDMI’s up to the TV at the same time as the power. If the customer doesn’t want the expense of extra electrical related work often I will just provide a longer power cable that will come out at the same place as the HDMI’s etc so that it still looks very neat.
Consider installing other cables which may be required at a later date at the same time, even if you don’t need them immediately. If you are chasing holes in walls, I recommend pulling a coax, a HDMI and data cable just to future proof where possible. If you have a soundbar or equipment to be installed with the TV, make sure you account and install the adequate cabling for this also! Sometimes referred to as a kettle lead, IEC C13 Power Cables have a 3 pin IEC C13 connector and are commonly found on PC base units, projectors, monitors and TVs. Angled IEC Power Cables are also available for making tight 90 degree turns where space is limited. IEC Power Leads can be extended using a C13 to C14 Extension Cable. I use all of the methods described in this blog, but I admit I much prefer the professional methods of installing a mains plug or fused spur. Obviously the customers budget needs to allow this and it can be a bit more work than would otherwise be necessary to do this. Future proof the electrical cabling where possible. You can’t be sure that a new TV that you connect in the future will be compatible
