What aspect distinguishes utility boxes from accessory boxes?

Utility boxes are primarily designed to serve service connections, which is a key aspect that distinguishes them from accessory boxes. This function involves facilitating the connection of electrical service from the utility provider to the residential or commercial electrical system. Utility boxes are installed where service drops from overhead lines or underground service connections come into a building, ensuring the safe and efficient management of electricity as it enters a building's electrical system.

Accessory boxes, in contrast, are generally used for mounting various electrical devices, such as outlets, switches, and light fixtures, rather than for connecting service lines. While utility boxes may be larger and can indeed hold more components due to their primary role, their defining characteristic is their use in the service connection process rather than their size or the number of devices they hold. This functional distinction is crucial for understanding their respective roles in electrical installations.
