A wide variety of types of electrical fittings options are available to you, such as hexagon.The term "electrical conduit" refers to durable tubing or other types of enclosure used to protect and provide a route for individual electrical wiring conductors. Conduit is typically required where wiring is exposed or where it might be subject to damage.

A conduit can be made of metal or plastic and may be rigid or flexible. All conduit is installed with compatible fittings couplings, elbows, connectors and electrical boxes, usually made of the same or similar material.

There are seven different types of conduit used commonly in residential and light commercial wiring. Rigid metal conduit, or RMC, is heavy-duty galvanized steel tubing that is installed with threaded fittings.

It is typically used outdoors to provide protection from damage and can also provide structural support for electrical cables, panels, and other equipment. RMC is sold in and foot lengths and has threads on both ends. Intermediate metal conduit, or IMC, is a thinner, lighter-weight version of rigid metal conduit and is approved for use in all of the same applications as RMC.

EMT is also called "thin-wall" conduit because it is thin and lightweight, especially compared to RMC. EMT is rigid but can be bent with a simple tool called a conduit bender. EMT is installed with couplings and fittings that are secured with setscrew or compression-type fasteners.

It is commonly used for exposed indoor wiring runs in residential and light commercial construction. If installed outdoors in exposed locations, it must be assembled with special watertight fittings.

Electrical nonmetallic tubing ENT is flexible corrugated plastic tubing that is moisture-resistant and flame-retardant. It is easy to bend and installs with snap-lock or glued plastic fittings. Unlike EMT, non-metallic tubing cannot installed in exposed locations, so it is commonly used inside walls. In addition to installation in standard wood- or metal-frame walls, ENT can be installed inside concrete block structures and can be covered with concrete.

Due to the blue color of one common brand of this conduit, ENT is nicknamed "smurf tube ," after the Smurfs cartoon characters. Flexible metal conduit FMC is also called "Greenfield," after the name of its inventor. It has a spiral construction that makes it flexible so it can snake through walls and other structures. Standard FMC is used in dry indoor locations, often for short runs between a wall box and a motor or fixed appliance, such as a garbage disposer.

Electrical conduit

Liquid-tight flexible metal conduit LFMC is a special type of flexible metal conduit that has a plastic coating and is used with sealed fittings to make it watertight.

It is commonly used with outdoor equipment, such as air conditioner units. Rigid polyvinyl chloride PVC is similar to plastic plumbing pipe and is installed with plastic fittings that are glued in place.

It can be bent after being heated in a portable heater box. Because the conduit tubing and fittings are glued together, the conduit assemblies can be watertight, making PVC suitable for direct burial in the ground for many applications.

The type of fitting you need depends on the type of conduit and the desired application. Use this buying guide to help you determine the right fittings for your project. For more information about choosing the correct conduit, consult our Conduit Buying Guide. Before You Start Before beginning any electrical project, refer to your local electrical codes and acquire any necessary permits.

Local electrical codes may influence which types of conduit and fittings you can use for specific projects and how they are installed. For more information, consult with your local inspector. Conduit Fitting Types There are a number of fitting shapes and parts that help you route your conduit in the most ideal pathway. Each type fulfills a different purpose:. Conduit Bodies This type of fitting is used to gain access to the interior of a raceway for wire pulling, inspection, and maintenance.

They can also be used to facilitate a change in direction or allow more bends to be made in a section of conduit. Couplers Couplers are used to join two lengths of non-flexible conduit together. Metallic couplers are available in both set screw and compression styles. Rigid PVC conduit is belled expanded on one end to allow the non-belled end of another length to be added without the need of a coupler.

Whether using a coupler or the factory-belled end, always use PVC primer and cement to join lengths of conduit. Connectors Connectors are used to attach conduit to an electrical box or enclosure. They are inserted into the round opening knockout and held in place with a locknut. Some connectors are designed to be quickly, easily snapped into the opening without a locknut, thus saving installation time.

Metallic connectors are available in several types, each for a specific type of conduit. Always use a connector that is listed for the type of conduit you will use. Insulating bushings are used to protect the wires from the sharp interior edge of the fitting. This is especially important when pulling wire into an electrical box or enclosure.

Bushings are threaded and placed over the locknut after it is tightened. When working with metallic electrical boxes and enclosures, always use an insulating grounding bushing. Reducing Washers Reducing washers are used with a locknut to reduce the size of the knockout opening to accommodate a smaller diameter conduit.

They are also used to reinforce concentric knockout rings where the conduit is subject to movement and could loosen or break the concentric rings. Always use reducing washers in pairs one on each side of the opening and fasten securely. Use appropriate straps to attach conduit to walls, ceiling, and framing members.A complete selection of conduit bodies, outlet boxes, device boxes, cable glands and other fittings for any environment.

If the air is filled with flammable vapors, dusts and other dangers, selecting the correct fitting is a must. Even in an ordinary location, the right fittings make the job easier while ensuring a safe, durable electrical system.

This is not the place to cut corners. Whether you are wiring a plant or an offshore oil platform, we have the top quality electrical fittings you need. The top quality electrical fittings you rely on in infrastructure and other industrial applications. When specifying electrical products for harsh environments choosing the right materials to ensure adequate corrosion resistance is crucial.

Wiring for modern homes is quite standard, and most homes built after the mids have similar types of wiring. Any new electrical installation requires new wiring that conforms to local building codes. It helps to understand a few basic terms used to describe wiring. In the case of household wiring, the conductor itself is usually copper or aluminum or copper-sheathed aluminum and is either a solid metal conductor or stranded wire.

Most wires in a home are insulated, meaning they are wrapped in a nonconductive plastic coating. One notable exception is ground wires, which are typically solid copper and are either insulated with green sheathing or uninsulated bare. The most common type of wiring in modern homes is in the form of nonmetallic NM cablewhich consists of two or more individual wires wrapped inside a protective plastic sheathing.

types of electrical fittings

As an alternative to NM cable, individual wires can be installed inside of a rigid or flexible metal or plastic tubing called conduit. Conduit is typically used where the wiring will be exposed and not hidden inside walls, floors, or ceilings. These larger wires in your home are carrying circuit voltage, and they can be very dangerous to touch. There are also several wires in your home that carry much lesser amounts of "low-voltage" current. These are less dangerous, and with some, the voltage carried is so low that there is virtually no chance of shock.

However, until you know exactly what kind of wires you are dealing with, it's best to treat them all as dangerous. Most NM cables have a flattened tubular shape and run invisibly through the walls and floor cavities of your home. Almost all of the wiring in outlets and light fixtures a modern home is NM cable.

Common Types of Electrical Wire Used in the Home

It is commonly used for supplying outdoor fixtures, such as lampposts. Like standard NM cable, UF contains insulated hot and neutral wires, plus a bare ground wire. But while sheathing on NM cable is a separate plastic wrap, UF cable sheathing is solid plastic that surrounds each wire. UF cable is normally sold with gray outer sheathing. UF cable is also used for major circuit wiring, and it carries a dangerous amount of voltage as long as the circuits are turned on.

Unlike NM cable, in which two or more individual insulated conductors are bundled inside a plastic sheathing, THHN and THWN wires are single conductors, each with its color-coded insulation. Instead of being protected by NM cable sheathing, these wires are protected by tubular metal or plastic conduit. Conduit is often used in unfinished areas, such as basements and garages, and for short exposed runs inside the home, such as wiring connections for garbage disposers and hot water heaters.

The letters indicate specific properties of the wire insulation:. Low-voltage wiring is used for circuits typically requiring 50 volts or less. Several common types are landscape lighting wire, sprinkler system connections, bell wire for doorbellsspeaker system wires, and thermostat wires. Wire sizes range from about 22 gauge to 12 gauge. Low-voltage wires typically are insulated and may be contained in cable sheathing or combined in twisted pairs, similar to lamp cord wire.

It must be used only for low-voltage applications. These are typically very small wires that are much different from standard circuit wiring. Serious shocks rarely occur with low-voltage wires, but it is still always best to turn off devices before working with them. Telephone cable may contain four or eight wires.

Category 5 Cat 5 cable, the most common type of household data wiring, contains eight wires wrapped together in four pairs. It can be used for both phone and data transmission and offers greater capacity and quality than standard phone wire.

Although data wiring does carry a small amount of voltage, anything under 30 volts is generally regarded as safe a household circuit carries about volts of power. However, there is always a danger of data wiring coming into contact with household wiring, so you should treat it with caution and avoid touching bare wires.

Coaxial cable is beginning to grow less common, thanks to the use of other forms of data wiring, such as HDMI, for television data transmission.
