What is the minimum wire bending space required for 350 kcmil conductors at a lay-in type lug connection?

For a lay-in type lug connection, the National Electrical Code (NEC) specifies that the bending space required for conductors must be sufficient to avoid damaging the conductors during installation. The minimum wire bending space is determined based on the size and type of the conductors involved.

In the case of 350 kcmil conductors, the NEC guidelines indicate that at least 5 inches of bending space is required. This distance allows for the proper installation of the conductors while ensuring that they are not excessively bent or twisted, which could potentially lead to insulation damage or reduce the conductor's performance.

The choice reflecting 5 inches as the minimum wire bending space meets the safety and operational requirements for such conductors, making it the appropriate selection in this scenario.
