How much minimum wire bending space is required for 350 kcmil conductors?

The minimum wire bending space required for 350 kcmil conductors is 5 inches. This requirement is established by the National Electrical Code (NEC), which outlines spacing to ensure that conductors can bend without inducing damage or excessive stress. Adequate bending space is crucial for maintaining the integrity of the conductor as well as ensuring safety during installation and operation.

Bending space is essential because it allows the conductor to be routed properly, reduces the likelihood of kinking, and ensures that the electrical insulation is not compromised by tight bends. Calculating and providing the correct amount of bending space is a key part of any electrical installation, especially when working with larger conductors like 350 kcmil, which require more space for proper bending radii. This is why the specified 5 inches is critical in practice.

The other options do not meet the NEC requirement for this conductor size, which is why they are not suitable answers.
