Which statement correctly describes the function of a conduit sleeve?

• A. It extends or protects conduit through walls or floors and provides a clean transition.
• B. It seals the end of a conduit to prevent air leakage.
• C. It replaces the need for conduit bodies.
• D. It grounds the conduit.

Answer: (A)

The main idea is that a conduit sleeve is there to let conduit pass through barriers like walls or floors safely and cleanly. It extends or protects the conduit at the edge where it meets the barrier, giving a smooth opening that reduces abrasion, keeps the conduit aligned, and helps maintain the integrity of the enclosure as wires pass through. This protective, transitional role is what makes it the best description. It isn’t meant to seal the end of a conduit to prevent air leakage, which is handled by end seals or plugs. It doesn’t replace conduit bodies, which provide access for pulling and bending around obstacles. And it doesn’t ground the conduit, since grounding involves bonding conductors to the metal enclosure.
