What characteristic of flexible conduit allows it to be effective in installations?

The effectiveness of flexible conduit in installations primarily stems from its ability to adapt to tight corners and obstructions. This adaptability allows it to navigate challenging spaces that a rigid conduit might struggle with, thereby reducing the need for additional fittings or labor-intensive adjustments. Flexibility is essential in environments where space constraints exist, and the ability to maneuver around existing structures facilitates quicker and more efficient installations.

The other characteristics do not contribute positively to the effectiveness of flexible conduit in the same way. Fixed bending capabilities would limit the conduit’s usefulness in diverse installation scenarios, heavy construction material might make installation cumbersome and less versatile, and increased friction from bends would actually hinder the efficient passage of wires. Therefore, the ability to curve and bend without compromise is what makes flexible conduit highly effective in complex setups.
