Which of the following is NOT a requirement for service-entrance conductors according to the NEC?

• A. Must be properly supported
• B. Must be lightweight
• C. Must comply with voltage drop requirements
• D. Must be sized based on the load

Answer: (B)

Service-entrance conductors are essential components in electrical installations, as they connect the main service panel to the external power supply. According to the National Electrical Code (NEC), these conductors must meet various requirements to ensure safety and efficacy in electrical systems. The requirement for service-entrance conductors to be properly supported emphasizes the importance of securing them in a manner that prevents sagging or damage. This support is critical to avoid wear and tear or any electrical hazards that could arise from loose wiring. The NEC also indicates that service-entrance conductors must comply with voltage drop requirements. This means that the conductor must be selected and installed in a way that minimizes energy loss and maintains adequate voltage levels throughout the electrical system. Moreover, conductors must be sized based on the load they are expected to carry. Proper sizing is crucial for safety and functionality, as undersized conductors can lead to overheating and potentially cause electrical fires. In contrast, the stipulation that service-entrance conductors must be lightweight is not a requirement outlined by the NEC. Conductors can vary in weight based on their materials, insulation, and construction, and their performance is not inherently linked to being lightweight. What matters more are the conductors' ability to safely
