While NM cable can be run inside a conduit, this is seldom done. They are similar to the wires you see when you strip the outer sheathing off of NM cable. Conduit always terminates at some type of electrical box or at fixed equipment that also serves as a box. Special connectors are used to secure conduits to boxes and to join lengths of conduits together to form long straight runs or bends.
The boxes, connectors, and conduits form a wire enclosure system called a raceway. A raceway is an enclosed conduit that forms a physical pathway for the electrical wiring to follow.
In this way, the metal raceway acts in place of the grounding wire that is found in non-metallic cable. This is also the main reason why only metal boxes may be used with metal conduit. This type of grounding system was more common in older construction than it is today, and many electricians today include an insulated ground wire in a metal conduit as preferred means of grounding the circuit. For a metal raceway to serve as a grounding system, all parts of the raceway must be electrically connected, with no interruptions.
If a remodeler unwittingly installs a plastic box in the raceway, or if any connection comes loose, the ground path will be broken, leaving the circuit ungrounded. Actively scan device characteristics for identification. Use precise geolocation data. Select personalised content.

Types of Electrical Conduits Electrical conduits may be rigid or flexible and may be made out of various materials like metal, aluminum, PVC or steel.
The Form 7 has an exclusive snap tight and wedgenut cover attachment to provide clear, unhindered cover opening. Mogul ex. Appleton BLBm has a large body size that facilitates pulling of large and heavy conductors and are used as cast covers for providing additional wiring area. Form 8 ex. Crouse LB38 The Form 8 ex. Form 9 ex. They also provide openings for splices and connect and change the direction in which the conduit runs. Its key benefit is that it provides access to conductors for maintenance.
Conduit bodies are used for various purposes in the electrical wiring system and the key reason is to offer protection to wiring from both natural and man-made elements. Conduit allows you to organize wires, protect your family, and meet local electrical codes. Conduits will make your home look cleaner as fewer wires will be exposed and help you when you have to fix any of the wires in case of a short circuit. Another benefit of using conduits within your home is that it makes replacing or fixing the wires easier.
More than three types of conduits are available in the market, but FMC, PVC, and plastic conduit are the most popular ones. Conduits are made with several materials that successfully provide sufficient protection to exposed wires within any structure or building.
Different types of conduits, therefore, are used for various requirements and different areas. Among the types of conduits on the market, the Flexible Metal Conduit FMC is well-known for protecting wires in dry and exposed areas within a building. If you want to protect exposed, short wirings in a tight area, such as water heaters, FMCs will be the right choice for this purpose.
The rigid PVC conduit or plastic conduit is also commonly used within most structures around us. PVC stands for Polyvinyl Chloride, and the conduits made from this material are similar to a regular plumbing pipe made of plastic. These types of conduits are easily bent by using heat and can be glued together to form connections. If you need a conduit for a larger area, these plastic conduits are the best option. They can be joined together quickly and can be bent to protect wires regardless of the electrical system.
Alongside having minimum weight, it is very rigid and sturdy, and thus, it requires a special tool called the conduit bender to be bent into the shape it needs to be. Since the EMTs are made using steel or aluminum, they are beneficial for safeguarding wires for electrical applications.
In addition, these conduits can conduct the electricity passing through them, thus providing an extra boost. EMTs are most commonly used to protect wires indoors, such as the lighting within our homes.
