One thing that all electrical projects have in common is electrical wiring. Knowing what sort of wire or cable you need is critical when installing new wiring. Knowing the different forms of electrical wiring will help you learn more about the circuits that already exist in your home. When looking at the junction box, for example, it will be easier to figure out which wire goes where. Any new wiring must adhere to local building rules as well as the Australian standards. Electrical wiring entails connecting wires and cables from various appliances, switches, lights, receptacles, and other devices to the main distribution board.
Which cable is used for house wiring?
Fire is a leading source of human death and property loss, hence fire safety is a top priority for most reputable wire and cable manufacturers. You should study a little about wiring and cables to better grasp this. Organic polymeric compounds are used to insulate cables. These are halogenated compounds comprising the elements chlorine, bromine, and fluorine. When heat is applied to the wires, the insulation begins to degrade, creating dense toxic smoke that causes suffocation and eye impairment. To combat this problem, cable producers have developed a variety of fire-resistant cables. FR (Fire Retardant) cables, FRLS (Fire Retardant Low Smoke) cables, LSZH (Low Smoke Zero Halogen) cables, and FS (Fire Survival) cables are the four types. In the home, these types of wiring are always recommended.
Manufacturers of wire and cable have also become more conscientious about adhering to national and international standards.
Wires and cables are everywhere, no matter where you go. Indeed, if we look about, we can see that we are surrounded by electrical products, wires, and cables in the shape of cell phones, computers, chargers, televisions, speakers, lamps, and other such items. As a result, these flexible power cables and wires have become a necessary component of our daily lives.
Non Metallic Sheathed Cable
The NM cable, is the most prevalent type of residential electrical wiring. Three or more independent conductors are bundled together in a sheathing, which is a flexible plastic jacket, in NM cables.
Appliances, fixtures, switches, and outlets are commonly wired using this type of cable in dry, interior home wiring. Today's NM cables are color-coded, which means the wire gauge is indicated by the colour of the cable's outer jacket. The following are the most frequent NM cables seen in modern homes:
Armored Cable
Local ordinances are more stringent than national codes when it comes to home electrical wiring. As a result, some localities may prohibit the usage of NM cables, instead opting for protected or AC wires.
AC wiring, also known as BX, dates from the early 1900s and features a flexible metallic covering that protects the conductors inside. Air conditioning is not permitted in business or residential structures with more than three stories.
Underground Feeder Cable
The UF (underground feeder) cable is a type of NM cable that is designed for moist areas and direct ground burial. The UF cable is required when running lines underground or to outdoor installations. Using PVC conduit underground and pushing wires through is another alternative that electricians use.
This cable has insulated hot and neutral wires, as well as a bare ground wire, and is typically used to serve outdoor fixtures. Unlike the NM cable, the UF cable has a grey outer wrapping and a solid plastic sheathing around each wire. This sort of cable can also be utilised for large circuit wiring.
Low Voltage Wire
Circuits that utilise less than 50 volts are wired with low-voltage wiring. For objects that do not use a lot of electricity, such as doorbells, thermostats, sprinkler systems, or landscape lighting, this type of wiring is the best option.
Low-voltage wiring is available in gauges ranging from 12 to 22 and is either insulated or coated in cable sheathing. Even while low-voltage wires rarely cause shocks, it is still a good idea to turn off your gadgets before working with them.
THHN/ THWN Wire
THHN and THWN are two of the most prevalent types of insulated wires. These are single conductors, unlike the NM cable, and each has its own color-coded insulation. They're also shielded by a plastic or metal tubular conduit.
Ground wires are green or yellow-green; hot wires are black, orange, or red; neutral wires are white or brown; and hot wires are black, orange, or red. In terms of insulation, the letters denote the following characteristics:
W stands for Rated for Wet Locations; N stands for Nylon-coated, for added protection; T stands for Thermoplastic; H stands for Heat-resistant, while HH signifies highly heat-resistant; W stands for Rated for Wet Locations; N stands for Nylon-coated, for added protection. These wires should only be used for short exposed runs, such as wiring connections for water heaters or garbage disposals, in basements or garages, and inside the house. These are circuit wires, and they should never be handled when the circuits are turned on.
Phone and Data Wire
Low-voltage lines are used in both phone and internet wiring.Your telephone and data line could contain anything from four to eight wires. The most efficient form for phone and data transmission has eight wires wrapped together in four pairs. Cable also has a higher capacity and quality than conventional phone wire.
