What is the minimum bend radius for an electrical wire bundle?

The minimum bend radius for an electrical wire bundle is important to ensure the integrity and longevity of the wires. When dealing with electrical wiring, bending them too tightly can damage the insulation or the conductors themselves, leading to potential failures or safety hazards.

In this case, a minimum bend radius of 10 times the outside diameter of the bundle is established as a standard practice. This guideline helps to distribute stress over a larger area and reduces the risk of kinks or pinching that might occur if the wires are bent more sharply. Maintaining this radius aids in preventing fatigue and electrical shorts, ensuring that the electrical system remains both functional and safe.

The other options suggest different bend radius factors which, while they may seem reasonable, do not adhere to the commonly accepted industry standard. Using a bend radius smaller than 10 times the diameter could increase the risk of damage to the wires and is not recommended for aircraft wiring safety practices.
