What is the recommended minimum bending radius for PVC conduit?

The recommended minimum bending radius for PVC conduit is critical for ensuring the integrity of both the conduit and the electrical conductors inside it. The minimum bending radius should be at least three times the diameter of the conduit. This standard helps to prevent damage to the conduit and the wires, which could occur if the conduit is bent too tightly.

By adhering to this minimum radius, you ensure that the conduit remains structurally sound, allowing it to protect the installed wiring effectively. Ensuring that bends are gradual and within the specified radius promotes better performance and longevity of the conduit and the electrical system overall. This guideline is particularly important in maintaining compliance with electrical codes and industry standards, which mandate such specifications for safety and reliability.

The other options, while they may reflect different practices, do not meet the widely accepted standard of three times the diameter, which is why that choice is the most appropriate recommendation for bending PVC conduit.
