About Electrical Wiring

Learning to buy the written electrical cables is as important as installing them with proper connections. You have to know what type of wires to use to carry out electrical repairs and remodelling. Start by learning the fundamentals of wiring materials and if you’re considering taking up any electrical project.

When researching wiring issues and selecting wiring for new installations and remodelling projects, knowing basic wiring terms and recognising the most common types of wire and cable can come in handy. Installing wiring is a bit different from other DIY projects. In this case, you have to be more scrupulous about choosing the wires and also while installing them. Read this article to find out more about them. Knowledge of the wiring systems will help you make the right choices while you are making the purchase.

A guide to electrical wiring for your home

Nobody can teach you all aspects of electrical wiring in just one article. It’s something that people take years to learn completely. But it all starts with the first step. So, let this article be your first step to learning about electrical wiring systems. Below are a few areas that you will have to focus on as a beginner. But keep in mind that when you start learning, you will realise how vast each of these topics can be. In this article, you will also find some really useful tips that you can follow while shopping for installation wires online.

Electrical cable colour codes

Both the outer sheathing of packaged electrical cables and the individual conduction wires inside cables or within conduit are colour coded. Understanding the colour coding scheme will assist you in determining the wiring and maintaining continuity within an electrical system. You can check the colour of the wire and can easily determine the size of the wires within the cable and the cable’s amperage rating. For example, 15-amp circuits require white-sheathed NM cable, while 20-amp circuits require yellow NM cable. Individual conducting wires signify their normal use rather than their size or rating. Black and red wires, for example, are for current-carrying or “hot” connections, while white wires are “neutral” conductors. These white wires are grounding ones of green-insulated and bare copper materials.

Non-metallic sheathed cable

Non-metallic, or NM, cable—also known by the brand name “Romex”—is used for the majority of interior wiring. NM cable is made up of three or more wires wrapped within a flexible plastic jacket or sheathing. Many interior circuits, such as those for sockets, switches, light fixtures, and appliances, are wired in this way. Learn how to select the best kind of NM cable for your next electrical project by understanding the fundamentals of NM cable.

Electrical wiring labelling

Markings are stamped or printed on the insulation or exterior sheathing of electrical wires and cable. This will give you an idea about the wire size, material, the type of insulation, and the number inside the cable. It will also help you determine any specific ratings or characteristics of the wire. Although looking at the colour of wire or cable at the store will help you narrow down your choices, reading the labels on the cables is the best way to ensure you get the right material for your project.

Installing the wires

In many countries, it is illegal for people without an electrical license to do the wiring. So, you have to check with your local laws before you take up the job of wiring yourself. Even if it is okay in your country to do the wiring yourself, you have to have the proper knowledge to do that. You have to know about what size of wires to use and where, you should know about the colour codes, and, above all, you should know about different types of different connections and circuits. If you are running wires outside a building, it should have thicker weatherproof insulation as well.

Tips on how to buy Electrical Wiring Materials

At first, buying installation wires for a DIY project might seem like a really simple thing to do. However, only when you are on the market to buy them will you understand how challenging it can be. There are so many different types of cables out there, each designed for a specific purpose. Like any other electrical equipment, using the wrong wire can turn out to be an expensive mistake. Here are some things to keep in mind while shopping for them online.

  • Size – Size is one of the important things to consider while buying electrical wiring material. For cables, the size of the wire determines the current rating. The current rating of the cable will be directionally proportional to the cross-sectional area of the conductor. Not using a conductor with the proper current rating will result in fire or the cable failing.
  • Length – This depends on how and where you want to run the cable. To get the cable length right the first time, you have to do a little planning. In complex wiring systems, you will have to have a wiring diagram to help you determine how long you want the wires to be.
  • Insulation type – There are a variety of different types of cable insulations. This depends on where the cable is supposed to be used. For example, wires designed for outdoor use will have thicker insulation, while wires that go inside conduits will have thinner insulation.
  • Cost – Electrical cables are not cheap. The key reason why these cables are expensive is the copper conductor in the cable. So, even the cheapest cable on the market will cost you a significant amount of money. However, there will be some level of price differences between brands. But always make sure that the wires you are choosing meet the minimum safety requirement for your use.

If you are a DIYer, you will need many more things apart from electrical wiring materials. These include things like screwdrivers, hammers, pliers, electrical plugs, cables, connectors, flooring materials, carpets, tiles, and more.

Question & Answer

How much does electrical wiring cost?

Not all electrical wires are created equal. In fact, the cost of cables depends on the size, length, insulation thickness and material, and brand. The cost increases exponentially with the size of the conductor. Usually, the size of the conductor refers to the thickness of the copper conductor inside the cable and not the entire cable itself. The more weather protection a cable has, the more it will cost. In order to estimate the cost of the wiring materials, you will have to figure out what type of cable you want and its length.

When should electrical wiring be replaced?

Electrical wiring should be replaced every fifteen years, according to most experts. However, this doesn’t mean that the wiring system will fall apart right at the fifteen-year mark. In some cases, you might start getting problems with the system even before that. And in other cases, the wiring might be good to go on for a couple of more years. So, the best way to determine whether or not you need to replace the wiring is to test the system for its integrity. There are various methods to do this, which are beyond the scope of this article.

Where to buy electrical wiring online in the UAE?

Safety should be the primary concern while buying electrical wiring materials. That means the material should be fireproof, and the insulation should be thick enough to prevent accidental short circuits.
