When splicing two #14 gauge wires, what type of splice should be used?

• A. Tape-and-wrap method
• B. Butt splice
• C. Wire connector/nut
• D. Solder joint with flux

Answer: (C)

Splicing two #14 conductors should be done with a listed wire connector because it provides a secure, insulated, code-approved connection for branch-circuit wiring. A wirenut sized for #14 grips the wires firmly and keeps the joint enclosed and protected inside a box, making it the most reliable and standard method for this situation. Tape-and-wrap isn’t an approved or dependable way to join conductors in modern electrical installations. A butt splice can be used in other applications, but it isn’t the typical, easiest option for a standard building wiring splice inside a junction box. Solder joints with flux may create a solid connection, but soldering inside a box introduces inspection and insulation concerns and is not the preferred method in everyday wiring; wire nuts are the simplest, safest, and most widely accepted choice for joining #14 conductors.
