If a bend radius is too tight, what is a likely consequence?

If a bend radius is too tight, what is a likely consequence?

• A. It improves flexibility.
• B. It reduces voltage drop.
• C. It increases current capacity.
• D. It risks insulation damage and code violations.

Answer: (D)

Placing cables with a bend radius that is too tight subjects the insulation and conductors to excessive bending stress. That can crack or damage the insulation at the bend, allowing moisture or contaminants to enter and weakening insulation resistance. It also increases the risk of arcing or shorted paths between conductors and typically violates installation standards and codes that specify minimum bend radii. So the main consequence is insulation damage and code violations.
