Best Wire for House Wiring & How to Choose One
There are some elements that are crucial to optimize electricity connections in your home. Some of the electrical equipment in your house would be really difficult to use without electrical power. The two crucial parts that are essential to electricity are wires and cables. These wires and cables make sure there is a constant supply of electricity to keep things running properly.
The best quality electric wires for house selection is essential for a variety of reasons. When it comes to electrical cables and wires, you have to keep in mind that safety comes first. Wires can be made of different shapes and are constructed of a variety of different materials. Any electrical system depends on wires and cables, and if they do not work properly, they can cause tragic consequences. In order to get around this problem, we are going to provide you with some advice on how to choose the right wires and cables for your home.
Wire Insulation’s Colour:
For the three phases, choose insulation in the colours red, yellow, and blue. Earth wire is made of green while the neutral wire is made of black. Three-phase best electric wires for homes often come in:
Phase 1 : RED.
Phase 2 : YELLOW.
Phase 3 : Blue.
Earth : Green.
Neutral : BLACK.
When there are numerous wires going together, coloured insulation can help you distinguish between them. The wired network can maintain organisation by using designated cables for various applications.
Wire Insulation Must Be Checked:
Select a three-layered electric wire for house wiring. The first layer of the three layers provides water resistance, the second layer provides heat or high-temperature resistance, and the third layer provides fire retardant properties. Additionally, the insulation should be capable of withstanding a temperature of plus 100 °C without melting. The safe and secure operation of your home’s electrical system depends on this component.
A Megger tester is used to assess insulation resistance. This is a portable device that resembles an ohmmeter in many ways and has a built-in generator for creating a DC voltage. The voltage, which is typically at least 500V, causes a current to flow across the insulation’s surface.
Select The Correct Cable Size:
The decision of cable size is influenced by three variables. Voltage control comes first. Second, current carrying capability and short circuit rating. Before selecting a cable size, consider these factors! Voltage regulation and short circuit rating are frequently ignored. This oversight may put your property in danger and harm the cable itself.
The most typical sizes used in residential construction are 12 and 14 gauge. By using the incorrect gauge of wire, heat resistance is created, which can soon become a fire hazard. Notably, each cable is made to support a particular level of voltage that is suited for a particular purpose. If you use a wire that is of the wrong size, it can end up melting because of the high current flow.
Choose The Material Of High Quality:
In general, copper and aluminium are used to make electrical wires and cables. However, you should only choose copper cables when choosing wires for your property. Additionally, select multi-stranded wires rather than single-stranded wires. In addition, the ISI mark, which denotes excellent quality, must be present on the electrical wire. The high-quality cables will be durable and safe, allowing you to both save money and safeguard your property.
You should always choose branded electrical products because they provide the highest level of safety and quality. It is advised to choose the appropriate type of wire for the appropriate area because you will be spending a sizable sum of money installing an electrical wire system for your home. For instance, different types of wires and cables are needed for exterior lines versus underground wiring.
Determine the Electrical Load:
Understanding the electrical load is crucial for ensuring both safety and efficient power distribution. To determine the electrical load, list all the electrical appliances and devices in your home, including lights, fans, air conditioners, refrigerators, TVs, computers, kitchen appliances, and any other devices that require electricity. Next, check the wattage rating of each appliance to understand the capacity required for each circuit.
Check Local Electrical Codes:
Familiarize yourself with local electrical codes and regulations. These codes outline the minimum requirements for wire size, insulation, grounding, and installation methods in house wiring. Adhering to these standards ensures safety and compliance. To fully understand the requirements, consult your local electrician.
Consider Special Requirements:
When selecting electric wires for your home, it’s important to identify special wiring needs for different areas. Kitchens and bathrooms, for example, require wires with higher insulation and moisture resistance due to exposure to water. Outdoor areas may need UV-resistant and weatherproof wiring. Understanding these specific needs ensures safety and durability in your home’s electrical system. For more tips on how to choose electric wire for a house, consider consulting local codes and professional advice.
Types of Electrical Wires for Home Wiring
-
Non-Metallic Sheathed Cable:
Non-Metallic Sheathed Cable (NM cable) is widely used for indoor residential wiring, offering an easy-to-install solution for connecting outlets, switches, and light fixtures. It contains insulated conductors and a ground wire, all enclosed in a flexible, non-metallic sheath. Its benefits include cost-effectiveness, flexibility, and suitability for most general-purpose wiring needs in dry, protected areas.
-
Armored Cable:
Armored cable, also known as BX or AC cable, features a metal casing that provides extra protection for the wires inside, making it ideal for use in walls, exposed areas, or outdoor locations. It’s commonly used where added durability and resistance to physical damage are needed. This cable is especially useful in commercial and industrial settings but can also be applied in residential projects requiring enhanced wire protection.

Underground Feeder (UF) cable is designed for direct burial without the need for additional conduit, making it ideal for outdoor wiring projects such as garden lighting or connecting outbuildings. It features heavy-duty insulation that resists moisture, UV radiation, and other environmental factors. This cable is commonly used where the wiring must be buried directly in the ground.
-
Individual Wires in Conduit:
Individual wires, such as THHN or THWN, are often used in conduit for flexible wiring solutions. They are ideal for areas where wiring needs to be routed through tight spaces or exposed to varying environmental conditions. Using conduit protects these wires from physical damage, moisture, and other external factors, ensuring a safe and durable installation.
-
Low-Voltage Wiring:
Low-voltage wiring is used for systems like home automation, security cameras, doorbells, and landscape lighting, requiring less power than standard electrical wiring. Its benefits include enhanced safety due to lower electrical risk, energy efficiency, and the ability to support advanced technological systems within a home. Low-voltage wiring is also easier to install and maintain, making it a popular choice for modern homes.
-
Coaxial Cable:
Coaxial cable is primarily used in home wiring for transmitting high-frequency signals, such as those for cable TV, internet, and digital audio connections. Its design, featuring a central conductor surrounded by insulation and a shielding layer, minimizes signal interference and ensures reliable data transmission. The benefits include superior signal quality, durability, and ease of installation.
