What is the proper method to install extension cords when suspending them from a ceiling?

Using hooks
String or cord
Tape
Metal clamps

The correct answer is: String or cord

The proper method to install extension cords when suspending them from a ceiling is to use string or cord. This method allows for a secure yet flexible installation, preventing damage to the cords and ensuring that they do not fall or sag excessively. String or cord can adequately support the weight of the extension cord while minimizing the risk of pinching or abrasion that could occur with other methods. When using string or cord, it is important to ensure that the extension cords are not tightly bound or constricted, maintaining a safe distance from sharp edges and providing adequate airflow to prevent overheating. Additionally, using a lighter material like string or cord reduces the risk of compromising the insulation or structural integrity of the electric cords. Other options such as hooks, tape, or metal clamps, while they may seem plausible, can lead to issues like wear and tear on the cords, making them more prone to damage. Fixtures like hooks may not securely hold the cords in place, while tape could fail over time, and metal clamps could lead to physical damage to the cord insulation. Therefore, using string or cord is the most effective and safest method for suspending extension cords from ceilings.
