Electrical Cable Supplier Provides various kinds of wire mostly made of aluminum or copper. The conductive materials are then protected by wires that supply electricity to different parts of your house.
If you’re making changes to your wiring, deciding on the correct wire or cable can be half the task. However, when looking at the old wiring in your house by identifying the wire’s type will tell you much about the circuit it is connected to (for instance, when you access a junction box and are trying to figure out the wires that go where). The wiring for modern homes is fairly standard, and the majority of houses built post-1960 have similar wiring. New electrical installations require the installation of new wiring that is compliant with the local building codes.
Below, you can learn about the various kinds of electrical wires used in homes to determine the most suitable solution for carrying out electrical projects safely and correctly.
The NM cable
Cable often identified as “Romex” in reference to a popular brand name Nonmetallic (NM) cables are a form of circuit wiring that is designed to be used in interior dry areas. It is the most commonly used kind of wiring used in modern houses. It is made up of at least two wires that are wrapped in a plastic sheath. NM cable typically contains at least one of the “hot” (current-carrying) wires as well as a neutral wire and the ground wire.
They have insulated the colours white (usually neutral) and black (usually hot) to make them suitable for installation. The majority of NM cables are tube shaped that is flattened and runs invisibly through the ceiling, walls and floor cavities of your house.
UF Cable
An underground Feeder (UF) can be described as a form of non-metallic cable that is designed for wet environments as well as direct burial in the ground. It is used most often to supply outdoor lighting, like lampposts. As with the standard NM cable UF includes insulated neutral and hot wires as well as an insulated copper ground wire. However, while the sheathing of NM cable is a distinct polymer wrap UF the sheathing for cable is made of solid plastic and is wrapped around every wire. This kind of electrical wire is also more costly than NM wire due to its long-lasting insulation. UF cables are typically sold with grey outer sheathing.
UF cable can also be utilized to connect major circuits It also carries an extremely high voltage for as long as the circuits are powered.
THHN/THWN Wire
THHN and THWN are codes for the two most popular types of insulated wires utilized in conduits. Contrary to NM cable, where there are two or more individual insulation-free conductors (copper or aluminum) wrapped in the plastic sheathing, THHN, as well as THWN, are both single conductors, each having its own coloured insulation. Instead of being secured with NM cable sheathing, they will be shielded by tubular plastic or metal conduit.
Conduit is typically employed in unfinished areas like garages and basements and also for shorter exposed runs within the home for wiring connections for garbage disposals as well as water heaters. They typically come with similar costs in comparison to NM wire (plus the cost of the conduit). The letters represent specific characteristics of the insulation of the wire:
Low-Voltage Wire
Low-voltage wiring is utilized for circuits that usually require 50 voltages or less. A few common kinds are landscape lighting wires as well as sprinkler system connections, bell wiring (for doorbells) as well as speaker system wires and thermostat wires. The sizes of wires vary from 22 gauges up to 12 gauges. These wires are made from aluminum or copper. Low-voltage wires are typically covered in insulation and are often contained in cable sheathing or with twisted pairs like lamp cord wire. It is only used for low-voltage purposes. They are usually very small wires, which are distinct from regular circuit wiring. Their prices are usually lower than the other wires used in homes.
Extreme shocks are rare in low-voltage wiring, however, it’s always advisable to shut off any devices prior to using them.
When replacing wiring in your house or installing new electrical wires it is essential to select the correct kind. Be sure to select an electrical cable specifically designed for the purpose you want to use it for.
