Which type of fittings are necessary to compensate for deflection in raceways?

Compensating for deflection in raceways is essential because, as temperatures change, materials can expand and contract. Expansion and deflection fittings are specifically designed to accommodate this movement, ensuring that the raceway structure remains intact and functional without creating undue stress or risk of damage to the electrical conductors inside.

These fittings allow for both lateral and axial movement, which effectively accommodates the natural fluctuations that occur with temperature changes. The use of expansion and deflection fittings contributes to maintaining the integrity and safety of the electrical system, preventing potential issues such as cable strain or failure.

Other types of fittings, while they may serve specific purposes, do not possess the same capability to address thermal expansion and directional deflection effectively.
