Question: 1 / 475

What is a common problem with service drops related to their positioning?

Wires located underground

Wires too close to doors or windows

Wires that are positioned too close to doors or windows create a safety hazard as they pose a risk of physical damage or accidental contact. When service drops (the overhead power lines connecting the utility pole to the building) are not adequately distanced from entry points, they can be subjected to unintentional impact from activities such as opening a door or window, which could lead to dangerous situations including electrical shock or short circuits.

Maintaining sufficient clearance from such areas is essential not only for the safety of individuals entering and exiting a building but also to ensure the integrity and reliability of the electrical service. Proper positioning helps to prevent wear and tear on the insulation of the wires, thereby reducing the risk of electrical faults.
