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

The requirement for a minimum length of free conductor at each outlet, junction, and switch point for splices is important for ensuring that there is enough conductor length to make secure connections without straining the conductors. A length of 6 inches is the standard in many electrical codes because it provides sufficient length to work with when making splices or connections. This length allows electricians to bend or maneuver the wires as necessary for proper installation and can accommodate any slight adjustments needed during work. Having too little conductor could lead to difficulties in making secure connections, which is crucial for both safety and functionality in electrical systems.
