Which fitting is essential for connecting two sections of conduit at an angle?

The elbow fitting is essential for connecting two sections of conduit at an angle because it is specifically designed to allow for directional changes in conduit runs. This fitting enables the seamless transition of conduits that need to change direction, such as a 90-degree turn or other angles, facilitating the routing of electrical wiring through complex layouts.

Elbow fittings come in various angles, allowing for flexibility in installation to meet specific design requirements. This is particularly important in both residential and commercial electrical systems where space constraints and architectural features may demand that conduits follow unconventional paths.

In contrast, straight connectors are designed for joining two straight sections of conduit in a linear fashion, while lock nuts and bushings serve different functions related to securing conduit fittings and protecting wires from sharp edges. Condulets are junction boxes used to house electrical connections and do not function as conduit angle connectors. Therefore, the elbow fitting is the appropriate choice for achieving the necessary angle connection between conduit sections.
