Can you supply one building through the interior of another building?

The correct answer indicates that supplying one building through the interior of another building is not permissible. This restriction is in place primarily due to safety and code compliance issues. Interconnecting buildings in this manner can create several potential hazards, which include risks associated with fire safety, electrical faults, and ease of access for emergency services.

The National Electrical Code (NEC) and local Ohio regulations mandate that electrical systems maintain clear distinctions between separate buildings to ensure that in the event of an emergency, each building can be independently managed and isolated. This isolation helps prevent the spread of electrical issues from one structure to another and simplifies maintenance and troubleshooting.

In most situations where buildings are physically connected, any electrical supply should be carefully evaluated to ensure that it adheres to safety regulations and standards, including proper ratings, overcurrent protection, and wiring methods. Thus, maintaining separate electrical services for each building is essential for compliance with safety standards and best practices in electrical design.
