Electrical conduits are tubes that bring electrical wires into the house and connect them to the general electrical system. Conduits are required everywhere a wire is exposed and at risk of being damaged, making them necessary both indoors and outdoors. Each conduit can typically accommodate two or more individual insulated wires. The conduit ends are linked to one another and to the rest of the home by various fittings and connectors.
In modern house building, there are seven major electrical conduit types that homeowners and electricians should be aware of.
Metal electrical tubing (EMT)
For interior exposed installations such as unfinished garages, Air conditioning Installation Perth, basements, or attics, EMT is the most commonly used conduit. Typically, the tubes are composed of galvanised steel or aluminium. They are hard, but with the use of a particular tool, they may be bent into the desired shape. EMT conduits are also known as thin-wall tubing because they are lighter and thinner than other tubing types. The usual tubing sizes are 1 inch and 112. They require waterproof fittings to produce a watertight seal because they run across interior walls.
Metal conduit that is rigid (RMC)
The RMC is made of strong galvanised steel and has threaded fittings. It is most commonly utilised outdoors and can offer structural support and stability to electrical boxes and panels. This is usually the most expensive tubing kind and has a minimum length of 10 feet, but it is simply the most durable for outdoor applications. It can also be buried for other purposes.
Intermediate metal conduit (IMC) For residential projects, IMC is typically used to replace the more durable and costlier RMC. It is lighter and thinner than the RMC, yet it provides comparable wire shielding. To save money, construction workers may use IMCs instead of RMCs for larger projects.
Metal flexible conduit (FMC)
The FMC, which is made of helical metal tubing, is easy to bend and is typically utilised in indoor applications. It is commonly used to link furnaces, lighting, and attic vents and can be threaded through walls. It works well in tight areas where other conduits cannot. FMCs can only be utilised in dry environments.
Flexible liquid-tight metal conduit (LFMC)
The LFMC is made of FMC tubing that has been coated with a waterproof plastic coating. Because of the added plastic coating, it is excellent for moist regions and LFMCs for water heaters and air conditioners. For specialised uses, it can also withstand being buried.
Electrical nonmetallic tubing (ENT) is a waterproof, flame-retardant corrugated tubing constructed of plastic. It is malleable in the hand, allowing it to fit into tight spaces. Because of its protective properties, it is suited for a variety of indoor and outdoor uses, including installation inside concrete structures. It is usually blue, which is why it is also known as a smurfing tube.
PVC rigid
This type of plastic tubing is typically found in corrosive conditions. It can be heated within a specific box to make it more malleable, and it is attached to its waterproof fittings to form a watertight seal. PVC is ideal for fast burying during construction and is simple to install. Although the tube is excellent for both damp and dry conditions, UV rays from the sun will destroy it over time.
Installing the proper electrical conduit helps improve home safety and prevent health risks. For prices on electrical conduits during construction or renovations, contact a qualified electrical service.
