How should electrical wires be properly terminated?

Proper termination of electrical wires is crucial for ensuring safe and effective electrical connections. Stripping wires to the correct length and securely connecting them with suitable connectors ensures that the connection is both secure and reliable. This method prevents issues such as poor connectivity, which can lead to overheating, arcing, or even electrical fires.

Using suitable connectors, such as terminal blocks, wire nuts, or connectors designed for the specific application, helps maintain the integrity of the connection in various environments. It also ensures that the wires are not exposed, minimizing the risk of accidental contact or short circuits.

The other options do not meet the essential safety and performance standards required for proper wire termination. For instance, twisting wires together tightly may provide a temporary connection but can lead to corrosion and is not a permanent solution. Leaving wires unconnected violates safety standards as it poses a risk of accidental contact and electric shock. Lastly, using electrical tape on exposed ends is only a temporary measure, failing to provide a secure connection necessary for reliable electrical systems.
