Which of the following is true about service disconnects according to NEC Article 230?

The correct choice highlights that each service must have its own means of disconnect. According to NEC Article 230, having a dedicated disconnect for each service ensures that there is a clear and accessible method for safely disconnecting power from that service. This requirement is crucial for maintenance, emergency response, and ensuring the safety of those working on electrical systems.

This emphasis on individual disconnects enhances safety by allowing for quick isolation of electrical services without impacting other systems. It also aligns with the code’s overall goal of promoting safety and reducing hazards where electrical work is conducted. Ensuring that each service has its own means of disconnect helps to maintain compliance with code requirements and provides peace of mind during maintenance and emergency situations.
