When pulling multiple cables through a junction box, what is the minimum length of wire that must be left for splicing?

Leaving a minimum length of 6 inches of wire for splicing when pulling multiple cables through a junction box is a standard practice in electrical installations. This length provides enough wire to make safe and effective connections between wires without putting undue strain on the conductors.

Having at least 6 inches of wire allows for flexibility during the splicing process, making it easier to manipulate the wires and ensuring that there is sufficient length to work with, particularly when securing wire nuts or other connectors. This extra length also helps to prevent the conductors from being pulled too tight, which can lead to damage or disconnection.

In summary, the requirement for leaving 6 inches of wire ensures safety and facilitates proper connections when splicing wires within a junction box, aligning with industry standards.
