Answer 1

The minimum height of span wires above residential driveways when operating on a system with 150 volts or less to ground may vary depending on specific regulations and safety standards.

Step-by-step explanation:

In order to determine the minimum height of span wires above residential driveways when operating on a system with 150 volts or less to ground, we need to refer to specific regulations and safety standards that may vary depending on the country or region.

However, as an example, in the United States, the National Electrical Safety Code (NESC) specifies a minimum clearance of 18 feet for residential driveways when operating on a system with 750 volts or less to ground. It is important to consult the specific regulations applicable to your location for an accurate answer.
