The minimum amount of free wire that must be left in a workbox is

Explanation:
Having enough slack on conductors inside a workbox is essential for safe, workable terminations. Six inches of free conductor is the standard minimum because it gives enough room to make splices, add pigtails if needed, and connect devices without pulling on terminals or stressing insulation. This length keeps wiring flexible enough for future service or changes while avoiding clutter and tension that can cause failures. Four inches is too short for reliable splices and clean terminations, while eight or ten inches adds unnecessary bulk without added safety in typical installations. Six inches strikes the right balance for safe, serviceable wiring.
