What is included in the interior of the service entrance cabinet?

The service entrance cabinet is a crucial component in an electrical system as it serves as the entry point for electricity into a building. It contains several essential electrical components that ensure effective power distribution and safety.

Included in the interior of the service entrance cabinet are items such as breakers, fuses, buses, and connections for grounding and bonding. These components work together to handle incoming electrical supply safely and reliably. The breakers or fuses protect the building’s wiring and connected appliances by interrupting the electrical flow in case of overloads or faults.

In contrast, wiring alone does not encapsulate the full breadth of what is housed within the cabinet, nor do grounding rods, which are external to the service entrance and focus primarily on safety. Therefore, the correct answer reflects the comprehensive nature of the cabinet, which is designed to contain all essential electrical components necessary for proper functionality and safety in a residential or commercial electrical system.
