What is a characteristic of flexible conduit?

Flexible conduit is typically made of materials such as metallic or non-metallic materials that allow for flexibility while providing some degree of protection for the wires contained within. The characteristic of being "made of twisted metal" reflects the common construction of certain types of flexible conduit, such as certain metal types, which can include a spiral or braided design that enhances its flexibility and durability.

Flexibility is a key feature of this type of conduit, making it advantageous for installations where the conduit needs to navigate around corners or fit into tight spaces. While it does offer protection to the wires, it may not provide the same level of shielding as rigid conduit options. Flexible conduits are not specifically limited to low voltage applications, which is why the reference to “less protection” is somewhat misleading; they do provide adequate protection for the intended applications. Overall, the characteristic highlights an important aspect of flexible conduits used in communication systems and other electrical installations.
