What is the primary purpose of flexible conduit?

• A. It provides physical protection and flexibility for wiring runs
• B. It increases current-carrying capacity
• C. It serves as a heat sink
• D. It reduces insulation resistance

Answer: (A)

Flexible conduit exists to give a protective, bendable path for electrical wires. It primarily guards conductors from physical damage and abrasion and makes installations easier where straight runs aren’t possible, because the conduit can bend and flex to follow walls, around corners, or through tight spaces. This protection and flexibility are its job; it does not raise how much current the wires can carry—the ampacity is set by the conductor size, insulation, and temperature, not by the conduit. It also isn’t designed to act as a heat sink, nor does it reduce insulation resistance.
