At what height should service supports be mounted?

• A. 10 feet
• B. 15 feet
• C. 20 feet
• D. 25 feet

Answer: (B)

The correct height for mounting service supports is 15 feet. This specification is important for maintaining safe clearances, particularly in areas where there may be vehicle traffic or pedestrian movement. The 15-foot height ensures that service wires are high enough to avoid contact with vehicles, including trucks and buses, which reduces the risk of accidents and enhances overall safety.

Additionally, this height is consistent with safety codes and standards set by utility commissions and electrical safety regulations. By adhering to these specifications, utility providers can ensure reliable and uninterrupted service while minimizing the potential for electrical hazards.

While the other heights presented might be appropriate in certain contexts or for specific applications, they do not meet the general safety standards required for service supports in typical residential and commercial applications.
