What precaution must be taken with conduits at joints or terminations?

• A. Should be welded
• B. Should be secured with screws
• C. Should be sealed
• D. Must have smooth transitions

Answer: (D)

Ensuring that conduits have smooth transitions at joints or terminations is crucial for several reasons related to both functionality and safety. Smooth transitions prevent damage to the wiring inside the conduit, as jagged edges or abrupt changes in direction can create wear and tear on insulation and conductors. Additionally, smooth transitions reduce the possibility of entrapment of moisture and other contaminates, which can lead to corrosion over time. Properly fitting conduits with smooth joints also maintain the structural integrity of the installation and can help reduce electromagnetic interference, which is essential for maintaining signal integrity in low-voltage and data applications. Thus, this precaution is fundamental for both the reliability of the electrical system and the longevity of the installation.
