How should electrical devices be connected to avoid hazards?

Connecting electrical devices securely and ensuring that all connections are insulated is crucial for preventing hazards such as electrical shock, short circuits, and fires. When connections are secure, the risk of loose contacts is minimized, which can lead to overheating and arcing—both of which pose significant safety threats. Additionally, using insulation not only protects the wires but also helps prevent accidental contact with live parts, further enhancing safety.

In contrast, choices that suggest loose connections or delay connections until the last minute compromise safety by increasing the likelihood of inadvertent disconnections or arcing. Similarly, relying solely on visible connections can lead to oversight of hidden potential hazards, as some connections might be under insulation and not readily visible. Therefore, ensuring that all electrical connections are secure and properly insulated is the best practice to avoid hazardous situations.
