When using non-removable lugs for 350 kcmil conductors, what is the required minimum wire bending space?

When dealing with non-removable lugs for large conductors such as 350 kcmil, the National Electrical Code (NEC) provides specific requirements for wire bending space to ensure safe and efficient installation. The minimum wire bending space is established to prevent damage to the insulation of the conductors and to maintain the integrity of the connection.

For a conductor size of 350 kcmil, the NEC specifies that the minimum wire bending space must be at least 12 inches. This requirement applies to scenarios where conductors are not installed in removable lugs, as they need adequate space to bend without causing stress or damage to the conductor insulation.

Thus, selecting 12 inches as the minimum wire bending space aligns with engineering practices focused on safety and compliance with NEC requirements. Ensuring that proper spacing is maintained allows for effective heat dissipation, decreases the risk of electrical faults, and facilitates smoother installations, ensuring that electrical systems operate efficiently and safely.
