How should wire splices be made in a junction box?

• A. By twisting wires together without connectors
• B. Using wire nuts or other approved connectors
• C. With electrical tape only
• D. By soldering wires together

Answer: (B)

Wire splices in a junction box should be made using wire nuts or other approved connectors to ensure safety and reliability. These connectors provide a secure and insulated junction that minimizes the risk of short circuits and electrical fires. Wire nuts, for instance, twist onto the exposed wire ends, creating a robust mechanical and electrical connection while also insulating the joint against moisture and dust. Using proper connectors is crucial because they are specifically designed to handle electrical loads, preventing issues such as overheating or loose connections over time. Additionally, these connectors help maintain the integrity of the electrical system, allowing for easy future troubleshooting and modifications if needed. Other methods such as twisting wires together without connectors, using only electrical tape, or soldering them lack the necessary safety and reliability standards required for electrical work. Twisting wires without connectors may lead to weak connections that can loosen and cause arcing or short circuits. Electrical tape alone is insufficient as it does not create a strong mechanical connection. Soldering can provide a solid joint but typically requires additional insulation and is not as effective for quick splices in a junction box format. Thus, using recognized and approved connectors is the safest and most effective practice for creating wire splices in junction boxes.
