Electrical Conduit Bodies

Conduit bodies are enclosure fittings used in electrical conduit systems to provide access for pulling, splicing, or routing wires, while also allowing for changes in direction. They come in various shapes, such as LB, T, C, and L configurations, to accommodate different conduit layouts. Conduit bodies are typically made from aluminum, cast iron, or PVC, depending on the environment and application, and often have removable covers to facilitate easy maintenance or inspection of conductors. They also provide additional space for wire bending and help to simplify complex conduit runs. Shop confidently with LiveWire Supply, where fast, flexible shipping is available for every order.

When should I use an LB conduit body versus a T or C configuration?

Use an LB conduit body when you need to make a 90-degree turn in the conduit system, typically when transitioning from a vertical to a horizontal run or vice versa, while maintaining access to the conductors for pulling or maintenance. A T conduit body is used when you need to split the conduit run into three directions, such as when one conduit path branches off from a main run. A C conduit body is used to provide straight-through access for pulling conductors in a straight conduit run, typically to facilitate wire pulling over long distances or to provide an inspection point. The choice depends on the direction changes and branching needs of your conduit layout.

What are the fill limitations for conduit bodies, and how do I calculate them?

Fill limitations for conduit bodies are specified to ensure there is adequate space for the conductors without causing damage during installation or compromising the system’s safety. According to the National Electrical Code (NEC), the fill calculation for conduit bodies is based on the internal volume, which must be marked on the conduit body. You can calculate the fill by comparing the total volume of the conductors to the listed cubic inch capacity of the conduit body. Each conductor size has an equivalent volume allowance in cubic inches, as specified in NEC Chapter 9, Table 5. Ensure the combined volume of all conductors does not exceed the conduit body’s rated capacity to remain code compliant.

Do conduit bodies affect the pulling tension of long wire runs?

Yes, conduit bodies can affect the pulling tension of long wire runs. When wires pass through a conduit body, especially in configurations like LBs or Ts that change direction, additional friction and resistance are introduced, which increases the pulling tension. This can make wire pulling more difficult, especially over long distances or with multiple bends in the conduit system. To minimize pulling tension, you can use lubrication, choose conduit bodies with smoother interiors, or strategically place pull boxes or larger conduit bodies to provide more space and reduce strain. Careful planning of conduit runs and conductor pulls is essential to avoid damaging the wires or exceeding allowable pulling tensions.

Are there limits on how many bends can be made before or after a conduit body in a run?

Yes, there are limits on the total number of bends in a conduit run, including those before or after a conduit body. According to the National Electrical Code (NEC), the total cumulative angle of bends between pull points, such as boxes or conduit bodies, must not exceed 360 degrees. This includes any combination of 90-degree, 45-degree, or smaller bends. The 360-degree limit is in place to make wire pulling manageable and to prevent excessive stress or damage to the conductors. If your run includes multiple bends, you may need to add additional pull points, such as junction boxes or conduit bodies, to stay within this limitation.

Can conduit bodies be used for splicing wires?

Yes, conduit bodies can be used for splicing wires, but only if they are specifically marked as suitable for splicing. The National Electrical Code (NEC) requires that conduit bodies used for splicing have an adequate internal volume to safely accommodate the splices without overcrowding. The volume capacity must be clearly marked on the conduit body, and the splices must be made in a way that maintains electrical safety and code compliance. If a conduit body is not rated for splicing, it should only be used for pulling or routing conductors, not for making splices. Always verify the conduit body’s rating and ensure that the installation meets NEC requirements.
