What is the minimum length of free conductor required at each outlet, junction, or switch point?

The minimum length of free conductor required at each outlet, junction, or switch point is set to ensure that there is enough wire available for proper connections and any potential future modifications or repairs. A length of 6 inches is generally sufficient for making secure connections, as it allows for sufficient flexibility in handling the wires without stressing the connections.

Having 6 inches of conductor available also helps to minimize the risk of wires being pulled on excessively, which could compromise the connections or the integrity of the electrical system. This requirement is established to enhance safety and maintain the reliability of electrical installations. Adhering to this guideline is essential for ensuring that proper practices are followed during installation, enabling clear and accessible workspaces for potential troubleshooting or upgrades without the need for excessive wire re-routing.
