For trade sizes up to 2 inches, conduit bends should be at least how many times the conduit diameter?

• A. 4x
• B. 6x
• C. 8x
• D. 10x

Answer: (B)

A bend should be made with a radius that’s large enough to avoid compressing the conductor insulation and to give a smooth path for pulling wires. When a conduit is bent too tightly, the inner surface of the bend is crushed and wires can snag or be damaged, making future pulls difficult or unsafe. For trade sizes up to 2 inches, the minimum centerline bend radius is six times the conduit diameter. This provides a gentle, workable curve that protects conductors and allows easy installation while still keeping the routing compact. Choosing a smaller radius (like four times the diameter) would be too tight for this size range, increasing the risk of damage and pulling trouble. A radius of eight or ten times the diameter would be more conservative and may be unnecessary for conduits up to 2 inches.
