What should be done if the service disconnect is located within a building?

When the service disconnect is located within a building, it is essential that it be readily accessible. This accessibility ensures that, in the event of an emergency or other situation requiring disconnection of power, authorized personnel can quickly reach the service disconnect without obstruction. The National Electrical Code (NEC) emphasizes the importance of accessibility to service equipment, allowing for safe and efficient operations, which is especially critical during emergencies such as fire or electrical faults.

While other considerations come into play for service disconnects—such as proper labeling, visibility, and secure enclosures—readily accessible means that anyone who needs to disconnect power can do so without significant delay or hazard. Accessibility is a fundamental requirement to ensure safety and functionality in electrical installations.
