Can NEC permit splicing of short branch wires with wire nuts to reach the breaker?

• A. Yes
• B. No
• C. Only with approved splice
• D. Not specified

Answer: (A)

Splicing branch conductors with an approved connector is allowed when you do it inside an accessible, listed junction or device box. A short piece of branch wiring can be joined with a wirenut to extend the run toward the breaker, as long as all splices are contained in a box, the box is accessible after installation, and the box fill is sufficient for the conductors and splices inside. Use the proper type of connectors for the conductors (copper-to-copper, or copper-to-aluminum with antioxidant and Al-Cu rated connectors, and follow torque requirements). In short, yes—you can splice short branch wires to reach the breaker, provided the splice is made inside a compliant box and meets all box-fill and accessibility requirements.
