The maximum number of 90-degree bends allowed between pull points in a conduit system is_____________.

In a conduit system, the number of allowable bends between pull points is significant for ensuring that wires can be easily pulled through without excessive force or risk of damage. The National Electrical Code (NEC) dictates that a maximum of four 90-degree bends is permitted between pull points in a conduit system.

This regulation allows for flexibility in design while maintaining functionality. With four bends, there is still a considerable chance for operators to execute the pull without encountering excessive resistance or complications due to too many curves. Additionally, having this allowance helps accommodate the realities of installation environments, where achieving perfectly straight runs may not be feasible due to structural constraints.

Limiting the number to fewer than four would reduce the versatility of conduit installation and could create scenarios where it would be difficult or impractical to route cables appropriately. In practical application, this guideline ensures that electricians have a feasible and safe means of pulling wire through complex pathways in buildings and structures.
