Electrician's Licensing Practice Exam

What type of service is simpler for running electricity across roadways?

1. Underground Service

2. Overhead Service

3. Hybrid Service

4. None of the above

The correct answer is: Overhead Service

Overhead service is often considered simpler for running electricity across roadways due to its construction and installation methods. Typically, overhead service utilizes poles and overhead lines, which can be easier and more cost-effective to install and maintain than underground systems. In areas where road crossings are required, overhead lines can span across roads without the need for extensive excavation or the complicated trenching required for underground service. This can minimize disruption to the existing infrastructure and reduce labor costs. Additionally, overhead systems can be accessed more easily for maintenance, allowing for quicker repairs or adjustments without the need for extensive digging. While hybrid service incorporates both underground and overhead elements, it may not be as straightforward or efficient for simply crossing roadways. Underground service, while very secure and less visible, often involves significant excavation and can be more complex and costly when dealing with roadways. These factors make overhead service the preferred choice for running electricity across roads in many situations.
