What is the proper way to splice wires?

Using wire connectors and wrapping them with electrical tape is the correct method for splicing wires because it provides a secure and safe connection. Wire connectors are specifically designed to mechanically join wires together and ensure good electrical contact. They prevent the wires from touching each other directly, which could lead to short circuits or other electrical hazards.

Wrapping the splice with electrical tape provides additional insulation and protection against moisture and physical damage. This method ensures that the connection is not only reliable but also compliant with electrical safety standards. It minimizes the risk of accidental disconnections or exposure to conductive surfaces, which can cause electrical shock or fire hazards.

In contrast, other methods such as twisting wires together and using duct tape do not provide a secure or insulative connection. Leaving wires exposed poses significant safety risks, and using solder without proper insulation could lead to connections that are susceptible to corrosion and physical instability over time. Therefore, the combination of wire connectors and electrical tape is the safest and most effective approach for splicing wires.
