If conductors are pulled through a device box, the NEC requires what minimum length of the conductors outside the box?

Explanation:
The key idea is that the NEC does not set a required minimum length for conductors that extend outside a device box when they are pulled through. What matters for code compliance is having enough conductor inside the box to make proper terminations and to provide proper strain relief for the conductors entering the devices or splices. There’s no fixed outside length you must leave hanging beyond the box, so no minimum outside length is required. In practice, you trim the conductors to the exact length needed to reach the terminals and to fit the box’s clamps and devices, rather than needing a specific outside extension.
