The proper way to attach an overhead electrical extension cord on a construction site is to use a method that avoids damaging the wire covering. This is essential for maintaining the safety and integrity of the electrical cord, as any damage to the insulation can lead to electrical hazards, including shocks and fires.

While staples might seem like a straightforward option for securing the extension cord, they can easily pierce or compress the insulation, leading to potential hazards. Similarly, nylon wire ties and string do not provide adequate support and may also risk damaging the cord if not handled carefully. In contrast, using a securing method that does not harm the wire covering, such as using adjustable clips or hooks designed to be gentle on cables, ensures that the cord remains intact and safe while still being secured in place. It's important to prioritize safety practices on site, especially when it comes to handling electrical equipment.
