Above-ground applications can make use of both flexible and stiff conduit. When utilizing flexible conduit, the materials should be fixed every 12 to 16 inches to prevent the conduit from drooping and causing the electrical wire within to become entangled. Stiffer rigid copper or aluminum tubing is required for more permanent installations such as outdoor lighting. The openings in the tubing should be no smaller than 1-1/4 inches by 3-8-3/4 inches to allow for future expansion of the cable.
Conduit is primarily used to carry one conductor (or multiple conductors with the same potential) of an electrical system from a distribution center or substation to the various outlets needed to provide power to different parts of a building. Conduits are available in sizes from 1/4 inch to 4 inches in diameter. The type of material used to create the conduit affects how it will react to environmental conditions. For example, plastic conduit will typically melt when exposed to heat while metal conduit will usually not require any special treatment to protect it from damage caused by weather conditions or physical stress on the system.
The conduits should be installed so that they remain in tension as they carry load. This means that they should not be allowed to dangle but rather be secured to a surface using a suitable method such as wiring screws or cable ties.
A flexible metal conduit is a type of pipe that is used to house electrical cables and other cabling. This type of conduit is commonly used in locations where metal strength is necessary but flexibility is also required. For example, this type of conduit is used in buildings where wall space is limited such as apartments or offices. The use of flexible metal conduit provides these advantages over rigid metal pipes because more than one cable can be housed within the conduit. This allows for increased wiring efficiency and for changes to be made easily as needed.
Flexible metal conduit is manufactured from aluminum or steel with an insulation coating on the inside surface. The length of the conduit varies depending on the application but most often it will be between 30 and 100 feet long. Conduit fittings are available for making connections to cables which enter the conduit at the exterior. These fittings can be opened or closed joints called couplings. Each end of the conduit contains two openings called elbows. One elbow is 90 degrees while the other elbow is 45 degrees. Both angles can be changed by inserting a third piece of conduit into the fitting. Cable terminations are provided at each end of the conduit and usually include screws which attach to the interior surface lining of the conduit.
The thickness of the insulation coating on the inside surface of the conduit affects the voltage rating of the system. The thicker the insulation, the greater the voltage tolerance.
PVC conduits are also employed in situations where electric wires must run beneath the earth or in an open environment exposed to air, dust, and water. Electrical metal conduits are ideal for applications in the basement or garage, where wire often runs down the surface of the wall. They can also be used when working with equipment that could cause damage to electrical wiring (such as a deep fryer). Electrical metal conduit is designed to support up to one inch of copper conductors within it. The conductor size depends on the application; usually between 14 and 16 AWG for household circuits and larger sizes for industrial applications.
Conduit is required in most cases where there will be any kind of movement of people or vehicles. This includes roads, sidewalks, driveways, and parking lots. If you plan to have many different types of equipment operating on a single circuit, metal conduit is the best choice because it can be easily separated into individual branches if needed.
PVC conduit is commonly used in residential construction because it's lightweight and can be easily handled during home repairs or remodeling projects. It's also suitable for outdoor use due to its resistance to weather conditions. However, indoor/outdoor use of PVC conduit requires special care because it's not rated to support electrical conductors. Also, because it's flexible, you should avoid using nails or screws to fasten it together when installing under flooring.
A tube used to cover and route electrical wires in a building or structure is known as an electrical conduit. The majority of conduit is stiff, although flexible conduit is employed for some applications. Conduit is typically erected by electricians at the location of electrical equipment installation. They may also have to cut conduit to length. Stiffer conduit is usually installed during construction of a building, while thinner-gauge wire can be routed through flexi-pipe if necessary.
Electrical conduit provides a safe way to enclose and protect electrical wiring while allowing it to be moved easily if needed. It also helps prevent damage to the wiring when vehicles drive over it. Conduit is available in various sizes, shapes, and materials to meet the needs of different applications. For example, utility companies use large quantities of metal pipe in their power distribution networks because it is easy to handle and does not break down when exposed to heat from electricity transmission lines.
You will often see metal conduit painted white or gray. This is required by law in some states where it is not clear where electricity flows. If you touch any part of the conduit while it is live, you will get shocked because your body will act as a ground for the electricity.
Conduit is used in all types of buildings, but it is especially useful for high-rise structures such as apartments, hotels, and offices.
