What is the minimum number of circuits required for convenience receptacles and lighting on temporary construction sites?

The minimum number of circuits required for convenience receptacles and lighting on temporary construction sites is two. This requirement is established primarily to ensure the safety and reliability of electrical systems in such settings.

Having two separate circuits allows for a dedicated circuit for lighting and another for receptacles. This segregation is crucial as it helps prevent overloading a single circuit, which can lead to tripping breakers or overheating, and ultimately, increases the risk of electrical fires. Additionally, it facilitates ongoing work even if one circuit experiences issues; the other may still maintain power for essential functions.

This practice is in accordance with the National Electrical Code (NEC) guidelines, which are designed ensuring safety and efficiency in construction environments. By implementing two circuits, it ensures that workers have access to both electrical power for tools and adequate lighting for safe operations, thereby enhancing the overall safety on site.
