According to NEC regulations, is it permissible to splice short branch circuit wires with wire nuts?

The correct answer indicates that splicing short branch circuit wires with wire nuts is permissible under applicable conditions set forth by the NEC (National Electrical Code). The NEC allows for the use of wire nuts, provided that the splicing conforms to safety standards and is executed properly. This includes ensuring that the wire nuts are rated for the wires being joined, that they are installed in a suitably insulated and accessible junction box, and that the connections maintain the integrity of the circuit.

Additionally, the NEC outlines specific conditions that must be met when splicing any electrical wires. This includes considerations about the type and size of the wires, the application, and the environment in which the splice is made. As long as these conditions are respected, using wire nuts for splices in branch circuits is acceptable. Thus, the key aspect is compliance with the NEC regulations, which grants allowance when conditions are met rather than outright prohibiting the practice.
